<P>PROBLEM TO BE SOLVED: To hold a movable-side beveled gear in a proper engaging position without increasing an energization force of an energization member, in a constitution in which the movable-side beveled gear is energized to the axial direction by the energization member and engaged with a fixed-side beveled gear. <P>SOLUTION: This power transmission mechanism is constituted so that tapered faces 337, 317 which abut on each other while opposing each other in the circumferential direction are formed at a slide shaft 331 of an output-side beveled gear 33 which receives a thrust load from an input-side beveled gear 52 and a cylinder 311 of an output shaft 31 which is penetrated with the slide shaft 331 so as to be movable in the axial direction, and when the tapered face 317 receives rotation torque from the tapered face 337, a thrust drag F2 is generated and the output-side beveled gear 33 is progressed by wedging action. The thrust load which the output-side beveled gear 33 receives offsets the thrust drag F2, and thus the engaging position of the output-side beveled gear 33 to the input-side beveled gear 52 at clutch connection is held. <P>COPYRIGHT: (C)2012,JPO&INPIT |
