PROBLEM TO BE SOLVED: To solve such problems that an engine mount is difficult to turn around X-axis and Y-axis, and the structure of the engine mount is complicated if the engine mount is turned around Z-axis. SOLUTION: Elastic members among a plurality of elastic members which are closest to a rear wheel comprise elastic members 131L and 131R with uniform elastic characteristics in the longitudinal direction. Remaining elastic members 133L, 133R, 135L and 135R comprise elastic members with non-uniform elastic characteristics which are hard in the vertical direction and soft in the longitudinal direction. If the elastic members with the characteristics soft in the longitudinal direction are used, the effect of the horizontal movement of the rear wheel in the right-and-left direction is weakened, and transmitted to a vehicle body frame. If the elastic members with the characteristics hard in the vertical direction are used, the behavior of the rear wheel to the vertical oscillation and the rotation in the right-and-left direction can be transmitted immediately to the vehicle body frame. Thus, the traveling property of a motorcycle during the high-speed traveling can be improved thereby.
