In the state of heavy load, the user can observe the distance between the bottom edge of the sleeve portion 62 and the warning mark 121 of the peripheral wall 12, if the bottom edge of the sleeve portion 62 of the cover 6 is relatively close to the When the warning mark 121 is used, it indicates that the supporting force of the elastic member 50 of the shock absorber is not good, and a better cushioning effect cannot be produced. The number of the shock absorbers can be appropriately increased to share the load negative load, for example, under the carrier 100. The shock absorbers are increased from four to six or eight. Further, as shown in Fig. 6, when vibration is generated, the shock absorbing purpose can be achieved by using the arrangement of the elastic members 5'. At the same time, the mounting base 20 is subjected to vibration, and the cylindrical member 32 is also caused to generate a longitudinal lifting motion and a lateral swing with respect to the base iq, and the gap between the sealing member and the damping oil 31 is utilized. The force can suppress the longitudinal momentum of the socket 2, and a longitudinal buffering effect can be generated. The bottom 321 of the cylinder wall 321 can be produced by the lateral momentum of the damping oil damper lag _ the mounting seat 2G. The load can be used to achieve better shock absorption. Further, the use of the material limit member 22 and the damping oil can produce an auxiliary cushioning effect. 5, as shown in Figure 7, when the ground on which the carrier (10) is to be placed is not flat, 10 1264504 causes the carrier 100 & to be placed on a plurality of shock absorbers. At this time, the user can operate the screw 4' according to the height difference of the ground and raise and lower the adjusting block 40 in the height direction, that is, the level of the carrier 100. 4 Therefore, the present invention is effective compared to the existing composite shock absorber: g knife
