As shown in this publication, the AW suspension arm has one end connected to a wheel support member that supports the wheel,
The other end is connected to two locations: a vehicle body side member closer to the wheel support center and a vehicle body side member farther from the wheel support center. The suspension arm is rotatably supported by two connecting portions of the vehicle body side member, so that the suspension arm can rotate up and down about the connecting portions. The two connecting portions between the suspension arm and the vehicle body side member are constituted by rubber bushing portions, and reduce vibrations (shimmy level) transmitted to the steering wheel.
