To enable an operator to easily connect a universal joint to an output shaft of an engine. A drive shaft is connected to an output shaft of an engine which is mounted on a vehicle body by way of a universal joint, and a wheel is connected to a distal end side of the drive shaft. Projection portions which project outwardly are formed on a yoke of the universal joint which is connected to the output shaft by way of splines. A swing arm is rockably supported on the vehicle body using one shaft, and the universal joint is arranged above the shaft. A boot is mounted between a distal end of the swing arm and a peripheral portion of the output shaft.
