Abstract: A front derailleur for a bicycle includes a chain guide reciprocably supported to a fixing member through a pair of linkage members. The chain guide has a pair of inner and outer plates opposite to each other and a coiled return spring interposed between the chain guide and either the fixing member or the linkage member. The return spring biases the chain guide in the direction of backward movement. A cap is provided to cover the spring to protect it from debris. The cap includes an elastically deformable cylindrical fitting portion to be fitted onto the coiled portion of the return spring. The cylindrical fitting portion has an axially extending slit which enables the cap to be fitted on the outer periphery of the coiled portion through expansion of the slit. The cap includes structure for positioning the cap such that the slit is adjacent to the inner plate of the chain guide.

Abstract: A chain guide in a front derailleur has an inner guide plate and an outer guide plate, the outer guide plate having a chain biasing region coming into contact with and biasing a driving chain when the chain is switched from a larger diameter front chain gear to a smaller diameter front chain gear and a chain moving region which is positioned below the biasing region and through which the chain moves when the chain is switched to the smaller diameter front gear. The chain moving region includes a swollen portion swelling outwardly with respect to the front chain gears, thereby eliminating sound generation without sacrificing speed change efficiency.

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.

Abstract: A derailleur for a bicycle, which is provided with a linkage mechanism comprising a base member, a pair of linkage members and a movable member having a chain guide, in which one of the four members constituting the linkage mechanism is provided with a mounting base entering into a space in the linkage mechanism. A tightening member having at the upper end thereof a control, is mounted to the base in the relation that the tightening member extends lengthwise vertically, so that a jig inserted into the space tightens the tightening member to thereby tightly grip the control wire.
