PROBLEM TO BE SOLVED: To reconcile toe angle change in the toe-in direction required for stability in a large bound time of the outside rear wheel in the turning direction with a small toe-in angle required for turning round property in the other time. SOLUTION: A bumper rubber 10 restricts a contraction stroke of a shock absorber 9 like (b) in the large bound time of a knuckle 4 of the outside rear wheel in the turning direction, so that upward oscillation (rising of elastic bush 6a) of a lower link 6 following the bound is noticeably constrained. Thus, the knuckle 4 is turned in the B direction about the center O of wheel rotation, and the elastic bushes 6a and 7b in the lower part of the knuckle 4 are displaced to the back side of a vehicle as shown in the solid line of (a). The lower links 6 and 7 are thus turned from broken lines to solid lines, the elastic bush 6a in the front part of the knuckle 4 moves inward in the car width direction, the elastic bush 7a in the rear part of the knuckle moves outward in the car width direction, and the toe angle of the knuckle 4 is changed in the toe-in direction as shown by C. |
