PURPOSE: To prevent a coil spring supported on the outer circumference of a shock absorber and a side frame from interfering with each other, without bending the side frame inside, or changing the sectional form of the side frame.
CONSTITUTION: In a knuckle 3 supporting a wheel Wf, the knuckle main body 3 is connected to a body through a lower arm 9, and in addition the knuckle arm 3 is connected to the body through an upper arm 5. Between the knuckle arm 3 and a body frame 25, a shock absorber 14 connecting the lower arm 9 to the body is provided. The height of the lower end of a coil spring 22 provided on the outer circumference of the shock absorber 14 is set so as to settle on the higher position than the height L of the upper face of the side frame 25, even at full rebounding when the shock absorber 14 expands at maximum.
