The holder mounted on the frame includes an operation button ejectable via a push spring, a bar member bent in a substantially U-shape and having one end fixed to the operation button and the other end ejectable to the outside of the holder, and a recessed portion into which a protruded portion formed in the lever is movably fitted. The lever rotatably attached to the holder includes the protruded portion fittable into the recessed portion and a recessed groove into which the bar member is fittable and which has a step. The wire is provided so that one end is fixed to the lever to thereby move the wire up and down. The braking member to which the other end of the wire is fixed is provided so that brake shoes are brought into contact with the wheels in accordance with the up and down movement of the wire.SELECTED DRAWING: Figure 1
