きくなって摩耗量が増大する。However, in the above-mentioned prior art, the entire inner surface of the inner collar is slid in contact with the outer surface of the shaft member, and the sliding load is large because the slidable contact area is relatively large. In addition, because the entire surface of the inner collar and the shaft member are in sliding contact with each other, a clearance of, for example, about 50 μm is set between the inner collar and the shaft member, and a radial load is applied due to such clearance. Occasionally, a tapping sound is generated due to the inner surface of the inner collar hitting the outer surface of the shaft member. Therefore, when a part of the inner collar is slid on the outer surface of the shaft member,
When the load increases, the frictional force on the sliding contact surface increases, and the amount of wear increases.

A pair of sliding contact portions that are always in sliding contact with the outer surface of the shaft member at both axial end portions of the shaft, and a connecting portion that integrally connects the two sliding contact portions.
The connecting portion is opposed to the outer surface of the shaft member at a distance in a low load state and has elasticity so as to contact the outer surface of the shaft member as the load increases . .
According to this feature, the inner collar is
The sliding contact portions at both ends are brought into sliding contact with the outer surface of the shaft member and
Because the connecting part is raised above the outer surface of the shaft member,
Dynamic load can be reduced. When the load becomes large
The connection part is elastically deformed and the inner surface of the inner collar
