<p>PURPOSE:To absorb two-stage impact, and prevent a gear sound by interposing a shock absorbing member, which allows relative rotation by being elastically deformed according to rotational torque and absorbs the impact, in the circumferential direction between a driven gear and a gear piece to mesh with a hub sleeve. CONSTITUTION:A clutch hub 2 is arranged on a rotary shaft 1, and a hub sleeve 3 slidably engaged in the shaft direction with the clutch hub 2 is arranged, and a synchronizer ring 4 which meshes with the hub sleeve 3 and has a taper cone part 42 is arranged. A driven gear 5 is arranged on the rotary shaft 1, and a gear piece 6 having a taper cone part 63 which meshes with the hub sleeve 3 and engages with the taper cone part 42 is arranged on the driven gear 5 so as to be relatively rotatable. An elastic member 7 is arranged between first and second projecting parts 51 and 61 between the driven gear 5 and the gear piece 6, and is elastically deformed according to acting rotational torque. In this way, twostage impact is prevented, and a gear sound is prevented.</p> |
