Claims

[Scope of utility model registration request]

The upper support structure is for a rod-shaped suspension member disposed between the body of the axle and the suspension arm, and includes a cylindrical body extending along the axis of the suspension member and surrounding the suspension member; an inner bushing made of a rubber-like elastic body fixed between the cylinder body, an outer bushing made of a rubber-like elastic body fixed between the cylinder body and the body, and the suspension member inside the cylinder body. and a first state in which the outer circumferential portion is fixed to the inner circumferential surface of the cylindrical body and a second state in which the outer circumferential portion is engaged with the inner circumferential surface of the cylindrical body are changed by fluid pressure. An upper support structure for a suspension member, characterized in that it has a hydraulic braking means.
