SOLUTION: The upper piston rod 3 of a damper 8 disposed at a rear body is attached to the rear part of the body, and its lower piston rod 5 is attached to the supporting frame of a wheel. If a vehicle is started or accelerated, since designated depressing force is applied on the rear part of the body, the piston 2 of the damper 8 is pushed down together with the piston rod 3 and a shell case 1 is moved downward. At this time, although oil 6 on the upper side of a piston valve 4 tends to flow below the valve 4, the flow is regulated by the hole 4' of the valve 4, and damping force is produced. Thereby, the depressing force produced at the rear part of the body is adsorbed and the rear part of the body is prevented from falling, and rectilinear stability is excellently maintained.
