<p><P>PROBLEM TO BE SOLVED: To provide a sliding structure of a rotor and an oscillator which allow easy assembly with an improvement in productivity. <P>SOLUTION: In the sliding structure of a rotor and an oscillator of a power transmission device having a rotor which is rotatably assembled inside an oscillator and causes rotational movement with an oscillating motion in the oscillator, a protrusion is provided on the outer periphery of the rotor. When the rotor is assembled inside rolling elements, the protrusion abuts against the rolling elements to restrain the axial movement of the rolling elements without abutting against a retainer. The axial movement of the rolling elements is restrained by a member abutting against the retainer on the opposite side of the protrusion in the axial direction. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
