Claims

[Claims for Utility Model Registration] (1) The upper end of the rod of the shock absorber is inserted into the attachment part of the shock absorber to the suspension insulator of the vehicle suspension, and A substantially cylindrical bumper spring made of an elastic material that is brought into contact with the cylinder of the shock absorber during displacement and elastically relieves such displacement; A straight upper cylindrical part with a large wall and a large pressure receiving area, and a thin wall with a small pressure receiving area located on the cylinder side of the shock absorber.
1. A bumper spring for a vehicle suspension, comprising a lower cylindrical portion bent in a bellows shape, and a rigid ring embedded in the upper cylindrical portion in the circumferential direction close to a boundary between the cylindrical portions. (2) The upper cylindrical portion is connected to an upper thick-walled cylindrical portion having the thickest wall and a lower cylindrical portion having a thinner wall thickness and a smaller outer diameter than the upper cylindrical portion. and a thick-walled cylindrical part, and the rigid ring is embedded in the lower thick-walled cylindrical part in a state of protruding a predetermined length from the outer circumferential surface of the lower thick-walled cylindrical part. Bumper spring as described in section.
