Abstract: A coupling structure for vehicle chassis members couples a ball joint member and an axle housing used for a vehicle to each other. The structure includes a socket that has a substantially columnar external shape, is provided in the ball joint member, and has a socket bolt groove throughout a circumference in an outer circumferential surface of the socket. The structure also includes a collar that has a substantially cylindrical shape and is disposed so as to surround an outer circumferential surface of the socket. The axle housing has a coupling hole having a substantially columnar internal shape into which the socket is inserted. The ball joint member and the axle housing are coupled to each other by disposing the socket in the coupling hole while the socket is surrounded by the collar.

Abstract: In a sub-frame module that is used to attach a set of left and right wheels in pair to a vehicle body, a sub-frame attached to the vehicle body and left and right hub carriers, to which the left and right wheels in pair are attached, are connected by left and right link arms to be capable of swinging. A stabilizer is laid across the left and right rear link arms, and a holder that holds the stabilizer is supported by an vehicle body side member that is provided in a bush attached to the vehicle body. The holder is fixed to the vehicle body by attaching the vehicle body side member to the vehicle body.

Abstract: A suspension device has longitudinal force compliance steer properties to steer a rear wheel to toe-in or toe-out according to increase in longitudinal force applied to wheel treads of a rear wheel. The suspension device includes: a hub bearing housing; suspension links having both edges pivotally attached to a vehicle body and a hub bearing respectively, to support the hub bearing housing; a suspension spring generating reaction force corresponding to relative displacement amount in the longitudinal direction of the hub bearing housing as to the vehicle body; a damper generating damping force corresponding to relative speed in the longitudinal direction of the hub bearing housing as to the vehicle body; and a toe change generating unit generating toe change in a direction where toe change due to longitudinal force compliance properties is temporarily cancelled out or suppressed at an early stage of turning of the vehicle.
