PROBLEM TO BE SOLVED: To reduce a possibility that a friction fastening element is brought into a fastened state by centrifugal hydraulic pressure.SOLUTION: A flywheel regeneration mechanism 10 transmits rotation which is transmitted between a drive source 1 and a continuously variable transmission 3 via a power transmission route to a flywheel 2 by a clutch CL3 which is interposed between a gear 111 being a rotating body at the power transmission route side and a gear 125 being a rotating body at the flywheel 2 side, and can store the rotation. The clutch CL3 is a hydraulic friction fastening element having a first friction plate 118 which rotates integrally with the gear 111, a friction plate 145 which rotates integrally with the gear 125, and a piston 150 which is pushed by hydraulic pressure supplied to a hydraulic chamber R, moves to a rotating axis X1, and relatively non-rotatably fastens the friction plate 118 and the friction plate 145 by pressing them to the rotating axis X1 direction. The hydraulic chamber R is arranged at the gear 125 being the rotating body which is lower in the highest rotational speed out of the gear 111 and the gear 125.SELECTED DRAWING: Figure 2
【課題】遠心油圧により摩擦締結要素が締結状態になる可能性を低減する。【解決手段】駆動源1と無段変速機3との間の動力伝達経路で伝達される回転を、動力伝達経路側の回転体である歯車111と、フライホイール2側の回転体である歯車125との間に介在させたクラッチCL3により、フライホイール2に伝達して蓄積可能としたフライホイール回生機構10であって、クラッチCL3は、歯車111と一体回転する摩擦板118と、歯車125と一体回転する摩擦板145と、油圧室Rに供給された油圧により押されて回転軸X1方向に移動して、摩擦板118と摩擦板145とを、回転軸X1方向に押圧して相対回転不能に締結するピストン150と、を有する油圧式の摩擦締結要素であり、油圧室Rを、歯車111と歯車125のうち、最高回転速度が低い方の回転体である歯車125に設けた構成とした。【選択図】図2
