Embodiment 1 A first embodiment of the present invention will be described with reference to FIGS. <Structure of Embodiment 1> The camera accessory holder according to the first embodiment of the present invention is of a type to be attached to an accessory shoe (hot shoe) of a camera, and is of a type using a telescopic rod 2 as an arm.

As shown in FIG. 1, the camera accessory holder according to the first embodiment includes a telescopic rod 2 and an accessory holder mounting foot 1 as a mounting part mounted on a base end of the telescopic rod 2. , Telescopic rod 2
And a clip 3 as a holding unit attached to the tip of the camera.

The telescopic rod 2 is composed of a plurality of mutually nested cylinders. Therefore, the cylinders can move in and out of each other and can rotate freely. However, since a stopper (not shown) is provided in the extending direction of each cylinder, there is no possibility that each cylinder will be separated. The cylinders constituting the telescopic rod 2 are locked at any telescopic and rotational positions by friction generated between them. Further, by receiving a force greater than this frictional force from the outside, they move forward and backward and rotate. The frictional force is set to be sufficiently larger than the weight of the accessory held by the camera accessory holder. Therefore, the telescopic rod 2 does not expand or contract unexpectedly against the weight of the accessory.

With the first joint constructed as described above, the clip 3 can be tilted integrally with the elbow 5 in the direction of arrow C with respect to the telescopic rod 2 and the arrow D with respect to the elbow 5. It can rotate 360 degrees in the direction. That is, the second joint has degrees of freedom in two orthogonal directions (C and D directions). Further, as described above, the distal end portion of the telescopic rod 2 is rotatable 360 degrees in the twisting direction (the direction of arrow E) with respect to the base end portion. Therefore, the clip 3 can take any posture with respect to the accessory holder mounting foot 1. That is, the second
Has a degree of freedom in three directions (C, D, and E directions) with respect to the base end of the telescopic rod 2.

Since each movable portion of the second joint has friction against its rotation (tilt), it does not rotate (tilt) unless an external force exceeding this frictional force is applied. The frictional force is set to be sufficiently larger than the weight of the accessory held by the camera accessory holder. Therefore, each movable part of the second joint does not rotate (tilt) unintentionally, losing the weight of the accessory.
