<P>PROBLEM TO BE SOLVED: To smoothly rotate a rotor by reducing rotational resistance, impact, or the like which the rotor receives while the power of a drive source is stably and precisely transmitted to the rotor. <P>SOLUTION: The rolling mechanism transmits the power of a driving source 20 to a rotor 40 so that the rotor 40 is rotated, with a play in a circumferential direction provided to the rotor 40 at the time of standstill. The rotor 40 is provided with an annular engagement part 41 across the entire circumference, and a roller member 62 is rotatably supported by an immovable part around the annular engagement part 41 almost parallel to the rotor 40. The roller member 62 is provided to be pressurized against the outer peripheral part of the annular engagement part 41 by the energizing force of an energizing member 63, so as to divert a pressurizing direction p thereof from the central axis of the rotor 40. <P>COPYRIGHT: (C)2013,JPO&INPIT |
