Vehicle suspension system

A vehicle suspension system, which restricts a maximum bump amount of a vehicle body, and connects a swing member rotatably supporting a wheel and swinging up and down to the vehicle body via a suspension spring, the vehicle suspension system comprises:

• a bump stopper provided on one of the swing member and the vehicle body, the bump stopper comprising:
• an axis;
• a substantially cylindrical tip end which abuts an abutment surface provided on the other one of the swing member and the vehicle body;
• and
• an apex formed at the tip end of the bump stopper,
• wherein abutment is initiated, in a circumferential direction of the tip end, in a state wherein the abutment surface inclines relative to the axis of the bump stopper, and
• wherein the apex at the tip end of the bump stopper first abuts the abutment surface and is located at an intermediate portion of the bump stopper in a direction of a wall thickness (t) of the bump stopper.
