Abstract
PURPOSE: To enable rapid and secure transmission operation by arranging a pair of right and left guide plates of a chain guide oscillatably supported on a base member in the inclined manner so that the interval between their inner faces is widened upward.
CONSTITUTION: A chain guide 4 of a front derailer is oscillatably supported relative to a base member 2 fixed to a frame, and its pair of guide plates 4b and 4c is arranged in the inclined manner so that the interval between its inner face is widened upward. Thus, when a chain is switched from a left sprocket S1 to a right sprocket S2, it acts so that the chain goes up onto the left guide plate 4b, while it goes up onto the right guide plate 4c in the reverse case. As the chain guide 4 is oscillatably supported to the base member through a single pin 5, transmission operation is made light. Thus, transmission operation can be done rapidly and securely.
