<p>PROBLEM TO BE SOLVED: To reduce size and to prevent a lowering of durability of a friction plate, in the structure of coupling a hub member, such as a clutch, to a sun gear. SOLUTION: A hub member 116 and a sun gear 121 are intercoupled through a connecting shell 160. The teeth of the outer peripheral part of the connecting shell 160 are engaged with the inner peripheral surface spline, and the connecting shell 160 and the hub member 116 are integrally rotatable. A stopper protruded in a way that cuts formed in the spline 136 are squeezed is formed on the hub member 116, and the connecting shell 160 is nipped between the stopper and a snap ring and is axially positioned. Since there is no fear of a weld strain occurring, the engaging position in an axial direction of the connecting shell 160 is overlapped with friction plates 137 and 138. And meanwhile, even when a backlash occurs to a sun gear, inclination due thereto is prevented from transmission to the hub member.</p> |
