Abstract

A suspension structure of a utility vehicle includes: a shock absorber; a knuckle; and an upper arm and a lower arm which connects the knuckle to a vehicle body frame of the utility vehicle, wherein a recessed portion which is recessed downward is formed on the upper arm, and a lower end of the shock absorber is supported by the recessed portion.

Claims

1. A suspension structure of a utility vehicle comprising:

a shock absorber;

a knuckle; and

an upper arm and a lower arm which connects the knuckle to a vehicle body frame of the utility vehicle, wherein

a recessed portion which is recessed downward is formed on the upper arm, and

a lower end of the shock absorber is supported by the recessed portion.

2. The suspension structure according to claim 1, wherein a bottom surface of the recessed portion is positioned substantially at the same height in a vertical direction as a support surface of the knuckle on which the knuckle supports the upper arm, or below the support surface.

3. The suspension structure according to claim 1, wherein an upper end of the shock absorber extends in a vehicle width direction, and is supported by a portion of a bonnet frame in a vicinity of a center portion of the bonnet frame in the vehicle width direction, the bonnet frame being positioned in a vicinity of a bonnet.

4. The suspension structure according to claim 1, wherein a stopper which regulates a displacement angle between the lower arm and the knuckle is formed on the knuckle.

5. The suspension structure according to claim 1, wherein the lower arm has a bent portion that bends upward at an intermediate portion of the lower arm in the vehicle width direction.

6. A suspension structure of a utility vehicle comprising:

a shock absorber;

a knuckle; and

an upper arm and a lower arm which connects the knuckle to a vehicle body frame of the utility vehicle, wherein

a stopper which regulates a displacement angle between the lower arm and the knuckle is formed on the knuckle.
