One end of an arm 11 is pivotally attached to the longitudinal center of the equalizer bar 9 via a pin 12 so as to be able to swing up and down, and the other end of the arm 11 is located at a position closer to the front of the rear axle 7F of the vehicle body 1. The fixed side 15a of the suspension cylinder 15 is pivotally connected to a bracket 13 provided in the arm 11 by a ball joint 14, and the fixed side 15a of the suspension cylinder 15 is connected to a ball joint 16 at a position near one end of the arm 11.
The movable side 15b is pivotally connected by a ball joint 18 to a bracket 17 provided at a rearward position from the front axle 7F of the vehicle body 1, and the suspension cylinder 15 and the arm 11 are connected by a ball joint 18. are connected at approximately 90 degrees and the ball joint 14
The ball joint 18 is located at approximately the same distance from the equalizer bar center 9a in the front-rear direction.
