To increase the axle load of a drive shaft via the driving force of the drive shaft when a vehicle is started by arranging an upper front torque rod and a lower rear torque rod inclinatorily forward, and arranging a lower front torque rod and an upper rear torque rod inclinatorily backward.
An upper front rod 5 is inclinatorily arranged forward and downward, and an upper rear rod 8 is inclinatorily arranged backward and downward. A lower front rod 15 is inclinatorily arranged forward and upward, and a lower front rod 15 is inclinatorily arranged backward and upward. If a rear front shaft 14 is used as a drive shaft, the driving force is received by a vehicle frame A via the upper front and rear rods 5, 8 and the lower front and rear rods 15, 18 when a vehicle is started, and the moment around the intersection between the extension line of the upper front rod 5 and the extension line of the lower front rod 15 is applied to the rear front shaft 14 as the reaction force. When the upper front rod 5 is inclined forward and the lower front rod 15 is inclined backward, the extension lines of them can cross each other in the front, the pressing force to the road surface by this moment is increased, and the axle load is increased.
