Claims

[Scope of utility model registration request]

a drive arm that is rotated at a constant speed by a drive from a drive source; an internal sun gear that does not rotate and is coaxially arranged with the drive arm; and an internal sun gear that is rotatably supported by the drive arm and that is rotatably supported by the drive arm. a cam follower that rotates at the same radial position as the pitch circle of the planetary gear in synchronization with the planetary gear; and a cam groove in which the cam follower is slidably fitted in the rotational radial direction; An indexing drive device comprising a driven arm arranged coaxially with the rotation axis of the arm, and an output shaft to which rotation of the driven arm is transmitted.
