嵩張ることもない。In this way, the second fixed leg 22 of each leg 20 is
The tripod device 1 can be easily switched to a movable type or a fixed type by a simple work of further sliding up and down with respect to the movable leg 23 and locking and unlocking with the leg lock lever 14. Therefore, since a single tripod device can be used for both fixed and movable shooting, it is not necessary to carry a video camera, a tripod device 1, and a pedestal for a tripod as in the conventional case.
It is not bulky.

Since 1 is made of a steel ball, the tripod device 1 can be reliably moved. Further, the bearing portion 3 of the holder 30
Since the felt 32 in which the lubricating oil is immersed is fitted into the through hole 30b penetrating the hole 0a, the ball roller 31 can always be smoothly rotated.

Further, although the felt in which the lubricating oil is immersed is used as the lubricating means provided in the holder, the lubricating means is not limited to the felt in which the lubricating oil is immersed, and may be grease (semi-solid oil lubricant) or the like. Further, according to the above-mentioned embodiment, the rod having the platform mounted thereon is provided so as to be able to move up and down with respect to the columnar column having the base mounted thereon, but the rod can be directly moved up and down with respect to the base. It goes without saying that the above embodiment can be applied to a tripod device of the type provided in FIG.

て使用することができる。As described above, according to the present invention, the rod on which the platform is mounted is provided so as to be able to move up and down with respect to the cylindrical support, and the base is mounted on the upper part of the support. ,
At least three legs, each of which is configured to be expandable and contractible by a tubular fixed leg and a movable leg accommodated in the fixed leg, are pivotally supported via respective base end portions, and these three legs are attached to the support column. In a tripod device which is foldable through a sliding staying and each stay having both ends pivotally supported between the staying and each leg, a second fixing is provided on an outer peripheral portion of a moving leg of each leg. A leg is provided slidably, a leg lock lever for locking the second fixed leg with respect to the movable leg is provided on the second fixed leg, and a stone ridge is provided on the outer peripheral portion of the tip end of the second fixed leg. On the other hand, since the roller is rotatably provided at the tip end of the movable leg via the holder, the roller of the movable leg of each leg is hidden in the second fixed leg and the second fixed leg is pierced by the stone. The tripod device can be used in a fixed state and the second fixed leg can be used. Move the tripod device by exposing the rollers of the moving legs by a simple operation such as to slide can be used.
