A steering damper (10) for reducing the inertia of steering that is attached in a low position relative to the steering shaft. The upper portion of a steering shaft (14) is fitted in the center of the rear of a top bridge (11) as a fitting part and a lower screw part (23d) of a shaft is tightened in the fitting part and is integrated with the fitting part. The shaft (23) is provided with a shaft main part (23b) having a small diameter extending in an axial direction of the steering shaft (14), when the shaft main part (23b) is made to pierce a turning shaft in the steering damper. A steering nut (24) is attached to an upper screw part (23a) at the upper end and the upper screw part (23a) is tightened. The steering damper (10) and the top bridge (11) are fixed to the upper portion of the steering shaft (14) by jointly fastening. Hereby, a steering nut (24) heretofore provided under the steering damper can be omitted and a position in which the steering damper (10) is attached can be lowered by the quantity. A rear portion of the liquid-operated steering damper is designed to fit into a space in the fuel tank so that it does not interfere with the front end of a fuel tank. The steering damper (10) does not interfere with the capacity of the fuel tank. <IMAGE>
