ABSTRACT:
An angular position adjusting device including a planetary gear mechanism intervening between a fixed member and a movable member rotatably arranged relative to the fixed member in such a way that the relative gear engagement position between an inner gear and an outer gear of said planetary gear mechanism is changeable when any one of the inner gear and outer gear is eccentrically rotated by an eccentrically rotatable member. The planetary gear mechanism is in engagement with one of the fixed member and the movable member and a torque limiting coupling means intervenes between the planetary gear mechanism and the other of the fixed member and the movable member. A motor for rotating the eccentrically rotatable member may be mounted on any one of the movable and fixed members. With a compact size a high gear reduction ratio and a high shock damping are realized.
