Patent number: 8840481Abstract: A power transmitting part for transmitting power has an annular main body section and a transmitting section. The transmitting section has a first protruding section extending outward in a radial direction from the main body section and a second protruding section extending toward a first side in an axial direction from a circumferential-direction-facing edge portion of the first protruding section.Type: GrantFiled: July 22, 2009Date of Patent: September 23, 2014Assignee: EXEDY CorporationInventors: Kozo Yamamoto, Keisuke Fujioka, Tomoki Hada, Kazuhiko Kawaguchi

Patent number: 8568243Abstract: A first flywheel assembly a first flywheel, a second flywheel, a first spring set, a first spring seat, and a second spring set. The first spring set is arranged between the first flywheel and the second flywheel in a pre-compressed state. The first spring seat is a member that supports an end portion of the first spring set and is pushed in a radially outward direction against the first flywheel. The second spring set is a member having a lower stiffness than a stiffness of the first spring set and is arranged between the second flywheel and the first spring set in a pre-compressed state such that it acts in series with the first spring set.Type: GrantFiled: August 6, 2009Date of Patent: October 29, 2013Assignee: EXEDY CorporationInventors: Kozo Yamamoto, Keisuke Fujioka, Tomoki Hada

Patent number: 8376864Abstract: A damper mechanism has a first rotating body, a second rotating body, at least one first elastic member, and at least one second elastic member. The second rotating body is disposed rotatably with respect to the first rotating body. The first elastic member is disposed so as to link elastically the first rotating body and the second rotating body in the rotation direction, and to operate only on the positive side of the torsional characteristics. The second elastic member is disposed so as to link elastically the first rotating body and the second rotating body in the rotation direction, and operate only on the negative side of the torsional characteristics.Type: GrantFiled: February 23, 2010Date of Patent: February 19, 2013Assignee: EXEDY CorporationInventors: Kozo Yamamoto, Keisuke Fujioka, Tomoki Hada

Patent number: 8066574Abstract: A damper mechanism 4 has a clutch plate 21 and a retaining plate 22 disposed aligned in the axial direction, a hub flange 6 disposed relatively rotatably in the axial direction between the plates 21 and 22, and a second coil spring 8 for elastically linking the plates 21 and 22 to the hub flange 6 in the rotational direction. The plates 21 and 22 have a pair of first main body components 28, and a plurality of linking components 31 that are disposed in the rotational direction between first protrusions 49 and second protrusions 57 and that link the pair of first main body components 28. The plurality of linking components 31 is disposed such that adjacent pitches are different.Type: GrantFiled: September 28, 2007Date of Patent: November 29, 2011Assignee: EXEDY CorporationInventors: Tomoki Hada, Hiroshi Uehara
