At this time, the sickle portion 34 approaches from the outdoor portion of the engaging portion 52 toward the first flat surface portion 63 in the stepped portion 61 of the receiving portion 42.

  FIG. 7 shows a cross-sectional view of the sickle storage portion 33 and the external shoji constituent portion 40 in a state where the sickle portion 34 is engaged with the receiving portion 42. When the sickle portion 34 is rotated so as to protrude to the outdoor side, the side surface portion 54 constituting the engaging portion 52 of the sickle portion 34 comes into sliding contact with the engaging surface portion 62 of the receiving portion 42. With the rotation of the sickle portion 34, the side surface portion 54 has a sliding contact position with respect to the engaging surface portion 62 along the longitudinal direction of the engaging surface portion 62, from the first flat surface portion 63 through the inclined surface portion 64, to the second flat surface portion. Move down to 65.

  When the sliding contact position of the side surface portion 54 is applied to the inclined surface portion 64, the sickle portion 34 receives a force toward the outer peripheral side of the shoji 3 by the tapered shape of the inclined surface portion 64. The receiving part 42 receives a force from the sickle part 34 toward the inner peripheral side of the shoji 3 as a reaction force. With these forces, the inner shoji 2 and the outer shoji 3 are each drawn toward the closing direction.

  The drawing of the inner and outer children 2 and 3 by the sickle portion 34 and the receiving portion 42 will be further described. In FIG. 8, the cross-sectional view showing the relationship between the sickle part 34 and the receiving part 42 is shown. FIG. 8A shows a state in which the side surface portion 54 of the sickle portion 34 is in sliding contact with the first flat surface portion 63 of the engagement surface portion 62 of the receiving portion 42. As described above, the side surface portion 54 of the sickle portion 34 is in sliding contact with the engagement surface portion 62 of the receiving portion 42, so that the outer shoji 3 cannot move toward the outer peripheral side, that is, cannot move in the opening direction. The shoji 2 and the external shoji 3 can be locked.

  FIG. 8B shows a state in which the side surface portion 54 of the sickle portion 34 is in sliding contact with the inclined surface portion 64 of the engagement surface portion 62 of the receiving portion 42. When the side surface portion 54 of the sickle portion 34 is in sliding contact with the inclined surface portion 64 from the first flat surface portion 63 side toward the second flat surface portion 65 side, the sickle portion 34 is moved to the outer peripheral side of the shoji 3 by the tapered inclined surface portion 64. The receiving part 42 receives a force toward the inner peripheral side of the external shoji 3 as a reaction force.

  Since the sickle portion 34 is fixed to the inner summoning cage 23 of the inner shoji 2, the inner summoning cage 23 tries to move toward the inner peripheral side of the inner shunt 2 by the force received from the receiving portion 42. That is, a force is applied in the direction in which the inner impeller 2 is closed. On the other hand, since the receiving part 42 is fixed to the outer summoning cage 24 of the external obstacle 3, the outer summoning cage 24 tries to move to the inner peripheral side of the external obstacle 3 by the force received from the sickle part 34. That is, a force in the direction in which the external shoji 3 is closed is applied.

  FIG. 8C shows a state in which the side surface portion 54 of the sickle portion 34 is in sliding contact with the second flat surface portion 65 of the engagement surface portion 62 of the receiving portion 42. Finally, the engaging portion 52 of the sickle portion 34 is engaged with the second flat surface portion 65, whereby the inner and outer obstacles 2 and 3 are closed between the side surface portion 54 and the engaging surface portion 62. The state where force is applied to is maintained.

  Thus, in the receiving part 42, the inclined surface part 64 is formed on the engaging surface part 62 of the stepped part 61, and the sickle part 34 is removed along the sliding contact direction when the sickle part 34 is rotated by the locking operation. When the inclined surface portion 64 is inclined in the direction of pressing toward the outer peripheral side of the shoji 3, it is possible to draw the inner shoji 2 and the outer shoji 3 as the sickle portion 34 is engaged with the receiving portion 42 and locked. It is possible to prevent a gap from being generated between them.

  Although the embodiment of the present invention has been described above, the application of the present invention is not limited to this embodiment, and can be applied in various ways within the scope of its technical idea.
