ABSTRACT:
A derailleur for a bicycle is disclosed which is so constructed that a first support is attached swingably through a first pivot shaft to a movable member which moves axially relative to a multistage sprocket assembly of the bicycle with respect to a base member and a second support is supported swingably to the first support through a second pivot shaft. A guide pulley is supported rotatably to the free end of the first support, and a tension pulley is supported rotatably to the free end of the second support. A rotary member is provided around the first pivot shaft, and a tension spring is interposed between the rotary member and the movable member. The tension spring rotates the rotary member in the direction of applying tension to a driving chain. An interlocking mechanism is interposed between the second support and the rotary member which allows an elastic force of the spring to act on the second support.
