Three-wheeled vehicle provided with swinging mechanism

The vehicle has a shock absorber with a swinging shaft for crosswise swinging a body frame for right and left two rear wheels. A damper rubber (112) is located between a pressing unit and a case on the side of the frame when the frame swings around the shaft. The rubber produces a reaction force to return the frame to an original position in which the unit and the case is attached to through pin separated from the shaft.
