As described above, according to the present invention,
Since the camera head is configured to be detachable from the arm, the operability when assembling and folding the arm and post is improved.

Further, since the arm is prevented from being folded unless the camera head is removed, the danger of folding operation is eliminated and the operation can be carried out with peace of mind.

Furthermore, since the camera head is stored in a dedicated storage portion during storage, handling during transportation is very easy, and since the camera head is protected by a cushioning material, it is damaged by vibration or the like. No worries.
