Patent number: 4951789Abstract: In a clutch assembly, a driven member is driven by a driving member through an engaging or clutch member which is mounted on the driven member movably between a position to be engaged with the driving member and a position to be released from the driving member. The engaging or clutch member is thrust toward the engaged position by a first thrusting force. A releasing member is movable between an active position to abut at one end thereof against the engaging or clutch member and an inactive position to be apart from the engaging member, and is thrust toward the abutting end by a second thrusting force. When the releasing member abuts against the engaging member, the releasing member is first moved in the opposite direction to the second thrusting force direction by a driving force of the driving member to reach a stop position, and then the engaging member is moved in the direction to be disengaged from the driving member by the driving force of the driving member.Type: GrantFiled: October 24, 1988Date of Patent: August 28, 1990Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shigeki Murata, Jirou Kajino, Hitoshi Minabe
