PURPOSE:To suppress the jolting of the equipment and improve the ordinary vibration absorptivity by absorbing ordinary vibration via the expansion or shrinkage of a spring and an elastic leg and receiving the lower face of a tube body with the flange of a guide body when a heavy weight is applied to a hard leg by the jolting or the like. CONSTITUTION:A guide body 14 is integrally molded with a cylinder section 14a opened on the lower face and a circular groove (flange section) 14b, and it is made of hard resin or the like. The projection 18a of an elastic leg 18 made of soft rubber is coupled with the cylinder section 14a of the guide body 14, and a restricting body 20d is inserted into a boss hole 16. The cylinder section 14a is inserted into a cylinder body 13 via a spring 23 under this condition, and the restricting body 20d is inserted into a coupling hole 17. The spring 23 is compressed under an ordinary load, the lower end of the cylinder body 13 is brought into contact with the circular groove 14b. When the equipment is jolted, the shock is damped by the expansion and shrinkage actions of the spring 23 and the projection 18a, the shock at the time of landing is absorbed by the support section 18b of the elastic leg 18, thereby the jolting of the equipment is suppressed. |
