Abstract (en)
A first main body is rotated by a motor. A second main body is revolved by the rotational force of the first main body. A hexagonal wall portion (64) is formed on the inner peripheral surface of the second main body. In a disc (24) fitted on the outer periphery of the boss (11) of the first main body are formed three elastic pressure members (21) so as to be arranged radially outwardly from the central axis of the disc (24). Each of the elastic pressure members (21) comprises a rubber elastic member (31), a contacting member (41) and a holding chamber (51). Each of the holding chambers (51) is enclosed by the disc (24) except for one portion opened at the outer peripheral wall of the first main body. The rubber elastic members (31) are held in the holding chambers (51). The contacting members (41) are housed in the holding chambers (51) and the distal portion of each of the contacting members is exposed at the open portion of each of the holding chambers (51). The exposed distal portions of the contacting members (41, 42, 43) are abutted against the hexagonal wall portion (64).
