  Therefore, according to the first aspect of the present invention, when the clip is attached to the boss portion of the automobile interior material, the engaging claws on the both side walls facing each other at the boss portion are exposed outward as in the prior art. Even if it is not forcibly inserted while spreading, it can be installed simply by engaging the pair of engaging arms with the engaging holes of the boss by rotating the base while hooking the hook of the base on the tip of the boss. This makes it easier to carry out the mounting work.

  In the invention according to claim 2, when the pair of engaging arms are engaged with the engaging holes of the boss portion, the lock claw formed on the tip edge of the one engaging arm is the boss portion. Since it catches on the hole edge of the engagement hole, there is no fear that the base of the clip will accidentally come off from the boss.

  In the invention according to claim 3, when the clip is attached to the boss portion of the automobile interior material, the engaging claws on both side walls facing each other close to each other at the boss portion are spread outward as in the prior art. Even if it is not forcibly inserted, it can be installed simply by engaging the engaging arm into the engaging hole of the boss part, rotating the base and hooking the lock claw of the base on the tip of the boss part. As a result, the mounting operation is easy.

  In the invention according to claim 4, when the engaging arm is finally engaged with the engaging hole of the boss portion, the step portion formed at the tip of the engaging arm is the boss portion. Since it bites into the hole edge of the engaging hole, there is no fear that the base of the clip will accidentally come off from the boss.

  In the present invention, a pair of engaging arms can be obtained by simply hooking the hook piece on the tip of the boss part or rotating the base body toward the boss part side while engaging the engaging arm in the engaging hole of the boss part. The clip is snapped onto the boss portion of the automobile interior material by engaging with the engagement hole of the boss portion or when the lock claw is hooked on the tip of the boss portion.

  Hereinafter, the present invention will be described in detail on the basis of preferred embodiments shown in the drawings. The mounting structure according to the first embodiment is similar to the conventional structure of an automobile interior material G such as a resin garnish as shown in FIG. A boss B is integrally projected on the back surface, and the boss B is engaged with a mounting hole H formed on the vehicle body panel P side via a clip C. Although it was developed for the purpose of being attached to P, it is characterized in that the following configuration is adopted.

  Therefore, first, the clip C will be described. The clip C is an integrally molded product of a synthetic resin, and as shown in FIG. 2, unlike the conventional case, is provided with a base 1 having a J-shape. The locking shoulder 2 that locks into the mounting hole H of the vehicle body panel P is formed as much as possible, and an elastic piece 4 extending in the direction of the enlarged tip 3 of the base body 1 is integrally provided upright on the inner surface side of the locking shoulder 2. A pair of engagement arms 5a and 5b that engage with engagement holes 22 formed in a boss portion B, which will be described later, are formed on the inner surface side front end portion of the piece 4 in a horizontally parallel state, and the rear end of the base 1 The hooking piece 6 that is hooked on the rear surface of the tip end of the boss B is formed in a standing state.

  As for the pair of engaging arms 5a and 5b, the upper one is formed into a long thin shape and the lower one is formed into a short thick shape so that the upper and lower engaging arms 5a. The interval of 5b is a width dimension that can be elastically engaged with the upper and lower edges that define the engagement hole 22 of the boss B, but in particular, for the tip edge of the upper engagement arm 5a, It is assumed that a relatively small lock claw 7 that is hooked from the back side is formed on the edge of the engagement hole 22 of the boss portion B. In the figure, reference numeral 8 denotes an inclined wall for preventing erroneous mounting, which protrudes from the lower surface of the inner surface of the substrate 1 to the bottom surface.

  Further, the boss B of the automobile interior material G has a plate shape, and has wide guide walls 21 extending only on the side where the J-shaped base 1 is mounted on both side edges. The base body 1 of the clip C is mounted between the guide walls 21, and an engagement hole 22 for engaging the pair of engagement arms 5 a and 5 b is opened in the central portion thereof, and the above-mentioned is provided at the lower end edge. A tapered surface portion 23 similar to the inclined wall 8 for preventing erroneous mounting is formed. It should be noted that the lower inner surface of the engagement hole 22 is positively provided with a slope 24 that slopes downward toward the side on which the base 1 is mounted.

  Therefore, in the case where the automobile interior material G is actually attached to the vehicle body panel P under the mounting structure of the first embodiment, first, the inclined wall 8 and the tapered surface portion 23 are aligned in the direction. 3, the upper part of the base body 1 itself is rotated to the boss part B side while the hook piece 6 formed on the rear end part of the base body 1 of the clip C is hooked on the back surface of the front end part of the boss part B. Then, as shown in FIG. 4, the pair of engaging arms 5a and 5b are engaged with the engaging holes 22 of the boss portion B, so that the clip C snap-fits to the boss portion B of the automobile interior material G. It is installed.

  Therefore, in the first embodiment, when the clip C is attached to the boss portion B of the automobile interior material G, the engaging claws on both side walls facing each other close to the boss portion B as in the past are outward. Since it is not necessary to forcibly insert it while pushing it wide, the mounting operation becomes easier, and under such a mounted state, as shown in the figure, the lock claw 7 formed on the upper engaging arm 5a has a boss portion B. Thus, the clip C itself is not accidentally detached from the boss portion B because it is firmly hooked to the edge of the engagement hole 22 from the back side.

  When the pair of engaging arms 5a and 5b are engaged with the engaging hole 22 of the boss B, as described above, the lower inner surface of the engaging hole 22 is on the side where the base body 1 is mounted. Since the inclined surface 24 inclined downward is provided, particularly when the lower engaging arm 5b is inserted into the engaging hole 22, it is smoothly engaged.

  Then, after that, if the clip C is inserted into the mounting hole H of the vehicle body panel P in such a mounted state, the base body 1 having the J-shape of the clip C bends inward as shown in FIG. Since the engagement shoulder 2 formed on the outer surface of the attachment hole H is elastically locked to the hole edge of the attachment hole H, the automobile interior material G can be attached to the vehicle body panel P side by one touch. Become.

  Next, the mounting structure according to the second embodiment will be described. The second embodiment basically follows the first embodiment as described above, but the difference is that FIG. As shown in FIG. 7, the pair of engaging arms 5a and 5b formed at the tip of the elastic piece 4 has a short thick wall on the upper side and a long side on the lower side. This is in the point that the lock claw 7 is formed on the tip edge of the lower engaging arm 5b.

  Therefore, even when the clip C is attached to the boss portion B even under the mounting structure of the second embodiment, similarly, the inclined wall 8 and the tapered surface portion 23 are aligned in the direction as shown in FIG. As shown in FIG. 7, the hook 1 formed on the rear end of the base 1 of the clip C is hooked on the back of the front end of the boss B, and the upper portion of the base 1 itself is rotated to the boss B side. As shown in FIG. 4, the pair of engaging arms 5a and 5b engage with the engaging hole 22 of the boss portion B, so that the clip C is attached to the boss portion B of the automobile interior material G in a snap-fit manner. The Rukoto.

  Therefore, even in the second embodiment, when the clip C is attached to the boss portion B of the automobile interior material G, the engaging claws on both side walls facing each other close to the boss portion B as in the conventional case are outwardly moved. It is not necessary to forcibly insert it while spreading it, so that the mounting operation becomes easier and under this mounting state, as shown in the figure, this time the lock claw formed on the lower engaging arm 5b. 7 is firmly hooked from the back side to the edge of the engagement hole 22 of the boss part B, so that the clip C itself is not accidentally detached from the boss part B. Since the other configurations / effects are the same as those of the first embodiment, the description thereof is omitted here.

  Further, the mounting structure according to the third embodiment will be described. The third embodiment is basically the same as the first embodiment described above. As shown in FIG. 9, one engagement arm 9 extending obliquely upward is formed at the distal end portion of the elastic piece 4 erected on the inner surface side of the base 1 of the clip C, and the distal end inner surface of the engagement arm 9 is formed. The stepped portion 10 that bites into the hole edge of the engagement hole 22 of the boss portion B is formed on the other hand, while the relatively small lock claw 11 that is caught on the rear surface of the tip edge of the boss portion B is formed on the lower end edge of the base 1. It is in the point. In this case, the inclined wall 8 is not provided.

  Therefore, in the case where the clip C is mounted on the boss B under the mounting structure of the third embodiment, as shown in FIG. When the lower portion of the base body 1 itself is rotated to the boss portion B side while engaging the engagement arm 9 into the engagement hole 22 of the boss portion B, the lock claw 11 is moved to the tip edge of the boss portion B as shown in FIG. Since it is automatically hooked on the back surface, the clip C is attached to the boss portion B of the automobile interior material G in a snap-fit manner.

  Therefore, even in the third embodiment, when the clip C is attached to the boss B of the automobile interior material G, the engaging claws on both side walls facing each other close to the boss B as in the past are moved outward. It is not necessary to forcibly insert it while spreading it, so that the mounting operation becomes easy. Under such a mounting state, the stepped portion 10 of the engaging arm 9 finally becomes the boss portion as shown in the figure. Since the hole edge of the engagement hole 22 of B is firmly bitten, the clip C itself is not accidentally detached from the boss portion B. In the case of the third embodiment as well, the other configurations and functions and effects are all the same as those of the first embodiment described above, so the description thereof is omitted here.

  Finally, the mounting structure according to the fourth embodiment will be described. The fourth embodiment is the same as the third embodiment described above, but the differences are shown in FIGS. As described above, the lock arm 12 that is hooked from the lower surface of the one engagement arm 9 to the edge of the engagement hole 22 of the boss B is integrally extended.

  Therefore, even when the clip C is attached to the boss B even under the mounting structure of the fourth embodiment, as shown in FIG. When the lower portion of the base body 1 itself is rotated to the boss portion B side while being engaged with the engagement hole 22 of the boss portion B with 12, the lock claw 11 is moved to the rear surface of the tip edge of the boss portion B as shown in FIG. Thus, the clip C is attached to the boss B of the automobile interior material G in a snap-fit manner.

  Therefore, even in the fourth embodiment, when the clip C is mounted on the boss B of the automobile interior material G, the engaging claws on both side walls facing each other close to the boss B are moved outward as in the prior art. It is not necessary to forcibly insert it while pushing it wide, so that the mounting operation becomes easier, and in such a mounted state, as shown in the figure, in addition to the biting of the stepped portion 10 of the engaging arm 9, Since the arm 12 is firmly hooked from the back side to the hole edge of the engagement hole 22 of the boss portion B, it is possible to more effectively prevent the clip C itself from being accidentally detached from the boss portion B. In the case of the fourth embodiment as well, all other configurations and functions and effects are the same as those of the first embodiment described above, and therefore the description thereof is omitted here.

  Since the attachment structure according to the present invention can easily attach the clip to the boss portion of the automobile interior material with a small force, it is advantageous when attaching an automobile resin garnish or the like to the vehicle body.
