PROBLEM TO BE SOLVED: To provide a bumper spring for a vehicle capable of suppressing noise due to its contact with a rod, elongating the durability thereof by suppressing the occurrence of buckling, and enabling the easy releasing of a mold in molding. SOLUTION: This bumper spring 10 comprises a spring body 11 and a mounting fitting 31 fixed to the axial upper end thereof integrally with each other. The upper end part of the rod 3 of a shock absorber is inserted into the insert hole of the spring body. The center hole 24 of the intermediate tube part 13 of the spring body is formed in a tubular shape parallel with the axial direction and its inner diameter is formed slightly larger than the outer diameter of the rod. Groove parts 25 extending in the radial outer direction and through the axial entire length are formed at a plurality of positions in the circumferential direction. COPYRIGHT: (C)2005,JPO&NCIPI |
