A shift lever device for use with a bicycle comprises a bracket having a pair of spaced walls, a stepped slide shaft slidably mounted on the bracket and formed with a plurality of stepwise reduced cylindrical sections of different diameter, a push-button mounted to one end of the slide shaft, a coil spring interposed between the push-button and one of the pair of walls for urging the slide shaft in one direction, and a lever pivotally mounted on a support shaft supported by the bracket. A base portion of the lever is interposed between the pair of spaced walls and provided with a contact surface which is operatively contactable with a selected one of the plurality of stepwise reduced cylindrical sections of the stepped slide shaft.
