A second member is rotated with respect to a first member more smoothly than in conventional structures. The present invention has a worm 50, and a main driving side worm wheel 40 and a driven side worm wheel 60 which are disposed across the worm 50. Both end portions of the worm 50 in an axial direction are axially supported by bearing parts. In a direction substantially orthogonal to an axial center of the worm 50, respective teeth of the main driving side worm wheel 40 and the driven side worm wheel 60 contact both sides of the worm in the direction substantially orthogonal to the axial center with a backlash, and are supported thereby. When the second member is relatively rotated with respect to the first member, the worm 50 rotates relatively with respect to the main driving side worm wheel 40. The driven side worm wheel 60 rotates by a rotational force of the worm 50, and a rotational force of the driven side worm wheel 60 is regenerated in the worm 50. Whirling vibrations of the worm 50 are suppressed, and relative rotation is performed smoothly.
