摘要：
PROBLEM TO BE SOLVED: To enable a thrust bearing to be avoided from being released from an engaging and supporting part even under a state in which teeth portions of a driving side clutch body and a driven side clutch body are not engaged to each other and their top portions are abutted to each other.SOLUTION: A thrust bearing 80 is placed at an abutting location between a pressing piston 101 and a driven side clutch body 86, the driven side clutch body 86 is formed with an engaging and supporting part 86D positioned at an inner peripheral side of the thrust bearing 80 so as to restrict a positional motion of the thrust bearing 80 in its radial direction and project toward the driving side clutch body 87, a length from the abutting part of the thrust bearing 80 against the pressing piston 101 to the protruding end part of the engaging and supporting part 86D is set to be longer than an engaging margin L1 in a direction along an axis center between the teeth part 87A of the driving side clutch body 87 and the teeth part 86A of the driven side clutch body 86.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2016,JPO&INPIT【課題】駆動側クラッチ体と従動側クラッチ体との歯部同士が噛み合わずに頂部同士が当接した状態であっても、スラストベアリングが係止支持部から外れることを回避できるようにする。【解決手段】押圧ピストン101と従動側クラッチ体86との当接箇所にスラストベアリング80を介装し、従動側クラッチ体86に、スラストベアリング80の径方向での位置移動を規制するようにスラストベアリング80の内周側に位置して駆動側クラッチ体87側へ突出する係止支持部86Dを形成し、スラストベアリング80の押圧ピストン101との当接箇所から係止支持部86Dの突出端部までの長さを、駆動側クラッチ体87の歯部87Aと従動側クラッチ体86の歯部86Aとの軸心に沿う方向での係合代L1よりも長く設定した。【選択図】図7
