摘要： A power unit is provided that reduces the frictional resistance between a clutch and a rotary shaft while at the same time prevents an increase in the size thereof. The power unit includes an oil catch member (39) having an inner circumferential surface (39a) positioned radially outward of a rotary shaft (21) relative to an outer circumferential surface (21a) of the rotary shaft (21) and spaced apart from the outer circumferential surface (21a). At least a portion of the oil catch member (39) is disposed between a bearing (34) and a first clutch member (25). An oil reservoir space (45) for storing oil is formed between the inner circumferential surface (39a) of the oil catch member (39) and the outer circumferential surface (21a) of the rotary shaft (21), the oil reservoir space (45) being in communication with a clearance gap (37) between the outer circumferential surface (21a) of the rotary shaft (21) and an inner circumferential surface (36a) of a bore (36) of the first clutch member (25).
