Abstract
A fixing structure is provided for a motorcycle including a swing arm by which an axle having at either end thereof a drive wheel and a torque damping mechanism fixed thereto respectively is rotatably supported substantially at the central part thereof. The fixing structure fixes a driven sprocket to a transversely inner part of an outside constituting member of the torque damping mechanism. The fixing structure includes a plurality of fixing lugs projectingly formed at predetermined intervals on the outer circumference of the outside constituting member, and a plurality of fixing lugs projectingly formed with a predetermined width on the inner circumference of the driven sprocket to be fixedly fastened in a detachable manner with the fixing lugs of the outside constituting member, respectively. The inside diameter of each of the fixing lugs of the driven sprocket is larger than the outside diameter of the outside constituting member itself; the inside diameter of the driven sprocket itself is larger than the outside diameter of each of the fixing lugs of the outside constituting member; and the predetermined width is set smaller than the predetermined intervals.
