<p>The invention relates to a speed change operating device for bicycles, which houses a shift positioning mechanism and can set a suitable amount of overshift for each of shift positions. The speed change operating device comprises a support, an operating body which is supported to be capable of operatively rotating about an axis of the support and drawing or taking up an end of a cable, an engagement body provided on one of the support and the operating body, and a positioning member (7) provided on the other of the support and the operating body and having a plurality of engaging portions (72a-72c). Upon rotating operation of the operating body, the engagement body is successively fitted into the plurality of engaging portions (72a-72c) of the positioning member (7) in an elastic manner to perform positioning action. The positioning member (7) is divided into a plurality of members (7a, 7b) comprising respective groups, into which the plurality of engaging portions (72a-72c) are divided. A first member (7a) can effect play of a predetermined angle relative to a member, on which the positioning member (7) is provided, about an axis of the support, and a second member (7b) can effect play of a predetermined angle relative to the first member (7a) or the support in an axial direction of the support.</p> |
