取は部は後側に向けられている。As shown in FIGS. 1 to 5, the vehicle body side mounting portion 11a and the strut side mounting portion 11b of the swing arm 11 have rubber bushes 12 interposed as shown in FIG. 1 or FIG. The bracket 13 and the strut 14 on the vehicle body side are bolted to each other and attached so as to be rotatable. The vehicle body side mounting portion has a large bifurcated shape, the strut side mounting portion has a small bifurcated shape, and the swing arm 11 is substantially H-shaped. The vehicle body side mounting portion is directed to the front side in the front-rear direction of the vehicle, and the strut chamfer is directed to the rear side.

とができ、操安性を良くする。When the strut type suspension is assembled in this way, when a lateral load is applied to the wheel 16 attached to the spindle 15, the rotation center of the vehicle body side attachment portion 11a of the swing arm 11 rotates by an angle α from the center line EE. And moves to the center line FF, the center of rotation of the strut side mounting portion 11b of the swing arm 11 rotates by an angle -β from the center line GG, and the center line H-H moves in the opposite direction. On the 16th side, the center line I-I rotates by the angle θ = α-β and moves to the center line J-J. From this, the toe angle can be changed to the toe-in side, improving maneuverability.

強固になる。(Effects of the Invention) As described above, the present invention makes the vehicle-body-side mounting portion into a large bifurcation,
A substantially H-shaped swing arm with a strut-side mounting portion formed into a small bifurcated shape is provided. The body-side mounting portion of this swing arm is directed to the front side in the vehicle front-rear direction, and the strut-side mounting portion is directed to the rear side. The root portion and the spindle are formed in a substantially L shape, the strut is positioned in a small forked portion of the strut side mounting portion of the swing arm, and the spindle is extended from the strut across the swing arm in the vehicle width direction of the vehicle. With this configuration, when the lateral load is applied, the center of rotation of the swing arm body-side mounting portion and the strut-side mounting portion will move in the opposite direction to the conventional one. Changes to the toe-in side, and maneuverability can be improved. Further, the moving direction of the rotation center of the vehicle body side mounting portion and the moving direction of the rotation center of the strut side mounting portion can be moved in opposite directions, and it is possible to adjust toe-in or toe-out as necessary. Optimal steering characteristics can be set, and maneuverability is improved. Therefore, the rubber bush can be softened, and road noise and the like can be reduced. In addition, since the swing arm's mounting part on the vehicle body has a large bifurcation, there is no twisting of the swing arm with respect to the vehicle body even when lateral load is applied, and the strut side mounting part has a small bifurcation, so that the strut and swing arm are firmly connected. Become.
