摘要： PROBLEM TO BE SOLVED: To provide a rear derailleur with a structure where a tension sprocket wheel does not come close to the ground too much even if a chain is wound on a large chain wheel, and to provide the rear derailleur having a wide range of applications in a wheel size, on/from which a wheel can be easily mounted/dismounted.
SOLUTION: A guide arm 23 and a tension arm 24 swing around a guide arm swing axis 232 and a tension arm swing axis 243 respectively. The arms 23 and 24 swing independently of each other and a distance between a guide sprocket wheel 231 and a tension sprocket wheel 241 changes in accordance with a speed change state.

摘要： PROBLEM TO BE SOLVED: To provide a bicycle rear derailleur in which a chain guide and a movable member are hardly brought into contact with a chain stay. SOLUTION: A bicycle rear derailleur 27 comprises a bracket 31, a base member 32, a torsional coil spring 55, a chain guide 33, a movable member 34, a link mechanism 35, and a first oscillation regulating mechanism 36. The bracket is fitted to a rear claw portion 30. The base member is freely oscillated to the bracket. The torsional coil spring urges the base member clockwise when viewed from the outside with respect to a fitting member. The chain guide guides the chain to a plurality of sprockets. The movable member is connected in an oscillating manner with the chain guide urged clockwise. The link mechanism connects the movable member to the base member. The first oscillation regulating mechanism is disposed between the bracket and the base member, and regulates the counterclockwise oscillating position opposite to the clockwise rotation of the base member.

摘要： PROBLEM TO BE SOLVED: To provide a small-sized electric derailleur never influenced by mud or dust in an electric shift control device for bicycle transmission device by rotating a link connecting member by a motor in an electric shift control device for bicycle transmission device, and relatively moving a movable member relative to a base member according to this rotation. SOLUTION: When a pivot 150 is rotated counterclockwise by a motor, a working arm 204 is rotated counterclockwise to pull one end 214 of a spring 218 upward. When no resistance is added to the motion of a movable member 158 at this time, the working arm 204 remains sitting on bearers 211A, 211B, and the spring 218 is raised on a spacer 188 by the upward movement of a link member 108. On the other hand, when a resistance is added to the motion of the movable member 158 as when a rider is not pedaling, the one end 214 of the spring 218 is rotated around the spacer 188 to increase the tension of the coil spring 218. Accordingly, the coil spring 218 stores the energy for shift motion.

摘要： PURPOSE: To provide a rear derailer for bicycles with sheet-metal structure without lowering the function, and facilitate manufacture of it. CONSTITUTION: A bracket 6 is energized around a first axis in relation to an adapter to give tensile force to a chain. When a shift lever unit is controlled to drive and operate a rear derailer, a plate body 26 is parallelly shifted in the direction parallel to the first axis, since the bracket 6, a first link 22, a second link 23, and the plate body 26 form a four-joint parallel link mechanism. The plate body 26 is energized around a second axis parallel to the first axis in oder for outer and inner plates 43, 45 to be supported on the plate body itself, and to give tensile force to the chain. Since a guide pulley and a tension pulley 57 which are to be engaged with the chain, are arranged on the plates 43, 45, the chain can be parallelly moved to change the engagement with a rear sprocket.
