Patent number: 9719561Abstract: A damper device includes a first member, a second member, an elastic member and a supporting member. The first member has two wall members separated from each other. The supporting member includes projections (preventing portion) that make contact with one of two wall portions (wall members) so as to prevent the supporting member and an elastic member from being inclined (falling, rotationally moving) in the axial direction.Type: GrantFiled: January 24, 2014Date of Patent: August 1, 2017Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Satoshi Nakagaito, Tomohiro Saeki, Yusaku Nishio, Hiroshi Kawazoe, Miki Torii

Patent number: 8795093Abstract: A torque fluctuation absorbing apparatus includes a first side plate, a second side plate, a lining plate disposed between the side plates, a connecting member that connects the side plates at a position that is radially inward relative to the lining plate, a pressure plate disposed between the second side plate and the lining plate, and an elastic member that biases the pressure plate toward the lining plate. The lining plate is slidably sandwiched between the first side plate and the pressure plate, and the first and second side plate each includes a reinforcing portion that includes a portion that is axially curved at a location that is radially outward relative to the connecting member.Type: GrantFiled: May 25, 2012Date of Patent: August 5, 2014Assignee: Aisin Seiki Kabushiki KaishaInventors: Tomohiro Saeki, Hiroshi Kawazoe, Hiroaki Suezaki, Yusaku Nishio, Tsutomu Sekine
