Patent number: 8105193Abstract: A bicycle rear derailleur is basically provided with a base member, a movable member and a moving mechanism. The movable member pivotally supports a chain guide. The moving mechanism is coupled between the base member and the movable member so that the movable member is movable relative to the base member. The chain guide includes a first guide plate, a second guide plate, a guide pulley rotatably disposed between the first and second guide plates and a tension pulley rotatably disposed between the first and second guide plates. The first and second guide plates are releasably coupled together by a tool-less connection.Type: GrantFiled: October 10, 2008Date of Patent: January 31, 2012Assignee: Shimano Inc.Inventors: Shinya Oseto, Hajime Nagasawa, Satoru Kunisawa

Publication number: 20070021246Abstract: A bicycle rear derailleur includes a bracket, a base member, a chain guide, a coupling mechanism and a support shaft. The bracket is arranged and configured for mounting to a bicycle frame. The bracket has a first mounting portion and a second mounting portion. The first mounting portion is formed with an open recess configured to at least partially receive a wheel axle. The base member is coupled to the second mounting portion of the bracket. The coupling mechanism is coupled between the base member and the chain guide so that the chain guide moves relative to the base member. The support shaft is configured to mount the base member to the bicycle frame at a location spaced apart from the open recess.Type: ApplicationFiled: July 19, 2005Publication date: January 25, 2007Applicant: Shimano Inc.Inventors: Satoshi Shahana, Hajime Nagasawa
