摘要： A derailleur for a bicycle is provided which includes a deformable linkage mechanism and is adapted to deform the linkage mechanism through a control wire for changing the bicycle speed. A saver arm is supported to the linkage mechanism to be forwardly and backwardly swingably. The control wire is fixed to the saver arm, and a saver spring is interposed between the saver arm and the linkage machanism, the saver arm includes a spring urging portion which deflects the saver spring when the saver arm swings forwardly and backwardly and applies to the saver arm a spring reaction to restore a saver arm in the direction opposite to the swinging direction thereof.

摘要： The device includes a positioning mechanism which is provided with a first end engaging portion for setting the low speed change stage, a second end engaging portion for setting the high speed change stage, and at least one intermediate engaging portion for setting the middle speed change stage. The device also includes an engaging member engageable with one of the engaging portions. In operation, a derailleur is actuated by the forward operation of a lever body of the speed control device to pull a control wire, and backward operation of the lever body loosens the control wire. The positioning member is provided with a displacement engaging portion which is in continuation of the intermediate engaging portion and is displaced in the direction of forward operation of the lever body with respect to the intermediate engaging portion. As a result, a chain guide of the derailleur can be positioned within a stable region with respect to each sprocket of a multistage sprocket assembly when the lever body is operated forwardly and backwardly.

摘要： A drive chain for use in a bicycle having a change-speed apparatus for example. In order to improve the engageability of the chain both in the chain running direction and in the chain deflecting direction for a change speed operation, the chain is constructed generally as a offset type having a series of alternately interconnected first plates and second plates. The improvement in the engageability in the two directions is provided by forming a middle portion of each first plate to be flush with or extend outwardly relative to a wide first connecting portion and also by forming a middle portion of each second plate to extend outwardly relative to the first connecting portion.
