Meanwhile, the first contracted part 310 may include an upper forming part 314, a lower forming part 316, and an air layer 312.

The upper forming part 314 is formed in the longitudinal direction of the upper end and may be located at the top of the second contracted part 260, and the lower forming part 316 is located inside the second contracted part 260 and has a hemispherical shape. It may be formed in the shape of, and the air layer 312 may be located in the center of the bottom forming portion 316 and may be formed as an empty space.

The shrinking frame 330 may be located inside the first shrinking portion 310.

More specifically, the shrinkable frame may include an inner elastic portion 333, an upper and lower space portion 332, and a shrinkage limiting portion 336.

The inner elastic portion 333 is in contact with the inner side of the upper forming portion 314 and is formed in the shape of 'ㄱ' and '『' and is positioned to face each other, and is formed in the shape of 'ㄱ' and '『' at the top. The portion protruding outward may be fitted and fixed into the fitting portion 250.

The inner elastic portion 333 may have a diameter that can be fitted and fixed into the fitting portion 250.

Additionally, the inner elastic portion 333 may be formed to contract and drive as the elastic portion 350 moves toward the upper end by the contraction drive of the elastic portion 350.

Here, the inner elastic portion 333 may be formed of a material such as rubber or silicone to enable contraction as the elastic portion 350 moves in the upper direction by the contraction drive of the elastic portion 350, but is limited thereto. However, as long as it is a material that is driven to contract by the pressure of the elastic portion 350, it can be included regardless of its name.

The upper and lower space parts 332 may refer to an empty space formed so that the elastic part 350 is located.

The shrinkage limiting portion 336 is located at the lower left side of the inner elastic portion 333, which is formed in an 'L' shape, and can limit the shrinkage length of the elastic portion 350 located in the upper and lower space portions 332.

That is, the contraction limiting portion 336 is formed of a hard material that does not contract, unlike the inner elastic portion 333, and can limit the distance that the elastic portion 350 moves in the upper direction by contracting.

The elastic part 350 is located at the inner bottom of the first contracted part 310, but the upper end is fixed to the contracted frame 330, and on the outside is a spring ( 354) is provided so it can be moved up and down.

Meanwhile, the elastic part 350 may be provided with an elastic support part 352 formed in the shape of 'ㅗ' at the center.

The elastic support portion 352 may be positioned with the upper protruding portion inserted into the upper and lower space portions 332 formed between the inner elastic portions 333 positioned to face each other.

In addition, the elastic support portion 352 is located at its lower end in the upper and lower space portions 332 and moves in the direction of the upper end by the spring 354 positioned to surround the outside, and then moves in the direction of the inner elastic portion 333 and the contraction limiting portion 336. Movement toward the top may be restricted due to contact with the bottom.

Through this, the lower end of the inner elastic part 333, which is formed in the shape of '『', can be contracted and driven to absorb the recoil that occurs when the elastic support part 352 moves in the upper direction by the spring 354.

The second contracted part 260 is formed with a diameter larger than that of the first contracted part 310 and is located at the bottom of the first contracted part 310, and can be driven to contract or relax by an external shock or vibration. there is.

The second contracting part 260 is provided with a bellows driving part 326 formed in a bellows shape at the lower center of the inner side, and can be driven to contract or relax by shock or vibration generated from the outside.

Meanwhile, the second contracted part 260 may have an insertion groove (not shown) formed at the top into which the first contracted part 310 is inserted.

The bellows driving part 326 may be formed in a shape corresponding to the shape of the lower end of the first contracted part 310, and its upper end may be in contact with the lower end of the first contracted part 310.

Additionally, the bellows driving part 326 may be driven to contract or relax to absorb shock or vibration applied to the first contracted part 310.

The fitting protrusion 370 is located at the bottom of the second contracted part 260 and is formed to have a diameter that penetrates the fitting part 250 and can be fixed to the fitting part 250.

In conclusion, the shock absorber 300 moves the first contracted part 310 downward into the second contracted part 260 by the contraction drive of the bellows driving part 326, and is driven by the bellows driving part 326. The air moves in the direction of the air layer 312, and the elastic portion 350 is driven upward by the spring 354 by the air flowing into the air layer 312 to absorb shock or vibration occurring from the outside. can perform its role.
