Patent number: 10539195Abstract: An engine clutch device includes first and second alternately stacked frictional power transmitting members and a clutch pressure member for axially bringing the frictional power transmitting members into pressure contact. The clutch device includes an oil supply portion adjacent to a distal end of power transmission shaft. The clutch device has an oil supply structure including a clutch lifter member with a flange portion axially facing the distal end of power transmission shaft, to axially shift the clutch pressure member to release the pressure contact of the frictional power transmitting members. The flange portion has a bowl-shaped portion extending axially to surround the one end portion of the power transmission shaft. The bowl-shaped portion including the flange portion functions to guide oil axially inward along the power transmission shaft and serves to provide an improved oil supply effect to the frictional power transmitting members.Type: GrantFiled: December 21, 2017Date of Patent: January 21, 2020Assignee: HONDA MOTOR CO., LTD.Inventors: Akira Tokito, Toshitaka Akita, Yoichiro Takahashi, Taichi Honda, Hitoshi Saito
