[0029] As a preferred embodiment, the diameter of the annular flange 121 is smaller than the inner diameter of the cylindrical groove 111.

[0030] As a preferred embodiment, it further includes a base 2, a support plate 3, a rubber vibration isolation pad, and a support seat 5. A plurality of shock absorber units 1 are connected to the upper part of the base 2 in an array distribution through the flange pieces of the outer shell 14.
