PROBLEM TO BE SOLVED: To prevent generation of noise when bound is inputted by forming a bumper rubber for a surface which is brought into contact with a damper rod and/or an upper sheet as a low frictional rubber. SOLUTION: A bumper rubber A is constituted by arranging a low frictional rubber 2 in the vicinity of a surface which is brought into contact with an upper sheet 13 and/or a damper rod 12 on a bumper rubber main body 1. A diameter of a rod inserting hole of the low frictional rubber 2 is formed smaller compared with that of the inserting hole 3 of the rubber main body 1. Since a part of the bumper rubber A is made of low frictional rubber if rubbing movement toward a relatively rotational direction between the damper 11 and an upper surface of the upper sheet 13 and the bumper rubber 1 and/or rubbing movement of a relatively axial direction between an inserting hole inner circumferential surface and a rod in association with compressive deformation of the bumper rubber 1 are/is generated when bound is inputted, the part is slid smoothly so as to prevent generation of noise. |
