2. Description of the Related Art For example, in a parallel link strut type independent suspension mechanism used in a vehicle rear suspension device shown in FIG. 6, when a wheel bounces or rebounds as shown in FIG. 2, the center X of the wheel A is a radius rod B.
3, the parallel link composed of the front and rear transverse links C rotates forward and backward around the connecting portion P as shown in FIG.

Further, a rearward force is applied to the wheel A at the time of braking and when the wheel bumps over the protrusion, whereby the transverse link C pivots rearward about the connecting portion P as shown in FIG. Further, the lateral force (cornering force) that the wheel A receives during cornering acts slightly behind the wheel center X as shown in FIG.

When the wheels toe change due to the rotational movement of these transverses or the cornering force received by the wheels, the vehicle behaves inadvertently. Therefore, it is necessary to minimize this toe change. If the axis along the swinging direction of each connecting portion is the rotation axis y, the following requirements are required for at least those connecting portions. That is, rigidity in the left-right direction of the vehicle (direction orthogonal to the rotation axis y) is required to resist the cornering force. Further, even if the transverse link C rotates in the front-rear direction of the vehicle (axial direction of the rotation axis y), the parallelogram formed by the chassis E, the link C, and the wheel A is retained. When,
The rigidity is required so that the transverse link does not rotate more than necessary due to the load applied during braking or the like. It should be noted that this requirement is the same for a suspension device that causes compliance toe in due to braking force, cornering force, etc., even if the specific numerical values differ.

Therefore, conventionally, a rubber bush is interposed between these connecting portions so as to satisfy the above requirements. Specifically, the material itself of the rubber bush is adjusted to make the rigidity and flexibility compatible with each other, or the rigidity and flexibility of the rubber bush used for the front and rear transverse links are changed. Alternatively, a metal interring is interposed in the rubber bush.
However, since the material of the rubber bush itself is also a rubber material, there is a limit in increasing the rigidity of the rotating shaft in the direction orthogonal to the rotating shaft.

According to this pillow ball bush, since a member having flexibility in the direction orthogonal to the rotating shaft is not interposed, there is an advantage that rigidity in that direction can be extremely increased. The flexibility and rigidity of the pillow ball bush in the direction of the axis of the rotating shaft is determined by adjusting the caulking force of the caulking metal fitting.

However, in the conventional pillow ball bush, the flexibility and the rigidity of the rotating shaft in the axial direction are performed only by adjusting the caulking force of the caulking metal fitting, which is troublesome.

An inner cylindrical body J is tightly fitted on the outer side of the connecting rod G. On the outer peripheral surface of the inner cylindrical body J, a spherical portion H having a center on its axis is projected. Further, a bearing M of dry metal or the like is interposed between the spherical portion H of the inner cylinder J and the inner peripheral surface of the outer cylinder L to support both cylinders J and L. The bearing M is slidably fitted at least in the axial direction into the inner hole of the outer cylindrical body L and slidable along the outer peripheral surface of the spherical portion H.
