Patent number: 7600625Abstract: A centrifugal clutch includes a clutch weight in a plane perpendicular to a rotation axis of an input member for enabling friction fitting to an inside of a clutch housing. The clutch weight is turnably supported by a drive plate. A grooved portion is provided on a clutch weight in a position that is opposite to a drive plate. At least one end of grooved portion is closed and is formed in a turning direction of the clutch. A damping rubber supported by the drive plate abuts against an inside face of the grooved portion. The damping rubber is held in the grooved portion in a compressed state by being compressed between the drive plate and the clutch weight. The centrifugal clutch so configured effectively inhibits vibration of a clutch weight when the clutch is let in, and minimizes both the parts required and man-hours for assembly.Type: GrantFiled: October 24, 2006Date of Patent: October 13, 2009Assignee: Honda Motor Co., Ltd.Inventors: Hideo Ishikawa, Michio Asumi, Hirokazu Komuro, Go Morita
