<p>A bicycle shift operating device (20) includes a mounting member (30), a shift operating member (32), a take-up member (34) and a retaining mechanism (36). The mounting member (30) includes a clamping portion (40) and a cover (42). The shift operating member (32) is rotatably coupled to the mounting member (30) to move in opposite rotation directions.
The take-up member (34) is arranged to selectively pull and release a shift control cable (21) in response to rotation of the shift operating member (32). The retaining mechanism (36) is arranged to retain the take-up member (34) in a plurality of positions. Preferably, a rotational angle limiting structure includes a first limiting portion (51c) formed on the clamping portion (40) and a second limiting portion (33e) formed on the shift operating member (32) that selectively engages the first limiting portion (51c) to limit rotational movement of the shift operating member (32). Preferably, the cover (42) has a bush (42b) integrally formed with the cover (42) as a one-piece, unitary member.</p> |
