To lubricate a friction material properly and improve controllability of a frictional engagement device.SOLUTION: A first frictional material support part (41A) is provided with a first oil passage (81) allowing an oil reservoir part (56) and a frictional material arrangement area (P) to communicate with each other. A second oil passage (82) which allows the oil reservoir part (56) and a space other than the friction material arrangement area (P) to communicate with each other is provided in at least one of a first support member (41) and a first pressing member (45). A second opening (82a) which is open to the oil reservoir part (56) side in the second oil passage (82) is disposed spaced apart from a first opening (81a), which is open to the oil reservoir part (56) side in the first oil passage (81), to the inner side in a radial direction (R).SELECTED DRAWING: Figure 4

    【課題】摩擦材の潤滑を適切に行いつつ、摩擦係合装置の制御性を向上させる。【解決手段】第1摩擦材支持部(41A)に、油溜め部(56)と摩擦材配置領域(P)とを連通する第1油路(81)が設けられ、第1支持部材(41)及び第1押圧部材(45)の少なくとも一方に、油溜め部(56)と摩擦材配置領域(P)以外の空間とを連通する第2油路(82)が設けられている。第2油路(82)における油溜め部(56)側に開口する第2開口部(82a)が、第1油路(81)における油溜め部(56)側に開口する第1開口部(81a)に対して径方向(R)の内側に離間して配置されている。【選択図】図4
