例えば円周方向に等間隔をおいて４個形成されている。As shown in FIG. 3, the buffer body 14 has a fluid chamber 16 containing 14 fluids such as oil, and the fluid chamber 16 is divided into two chambers 16a and 16b by a partition wall 18. The two chambers 16a and 16b are communicated with each other by an A life chair 18a formed in the partition wall 18. The fluid chamber 1G forms a ring-shaped groove on the upper surface of the ring-shaped buffer 14, and connects this groove upwardly from above. -13 is formed by sealing. The partition wall 18 has a ring shape, and the two chambers 16a and IGb divided by the partition wall 18 are located vertically, that is, the upper spring 17b side and the upper seat 13 side (vehicle body side member 1
2 side) in the fluid chamber 16. -L&l! For example, four 4-leaf feet 18a are formed on the partition wall 18 at equal intervals in the circumferential direction.

極めて効率的に阻止される。Constructed as above! A single side member 12 that supports the coil spring upper end 7b and the -L end 1b.
According to this suspension device, which is provided between the wheel 1
A high frequency vibration is generated from 1111 through the coil spring 7.
When the information is transmitted to the 8 body 14, the mw body 14 is deformed by the imaging, and this deformation changes the shape of the fluid chamber 16, changes the volume of the upper chamber 1ea and the lower chamber 16b, and causes the flow from one chamber to the other. Fluid enters and exits the chamber and from the other chamber through the A-rifice and the 7
Since the high frequency waves are absorbed and reduced by the inflow and outflow of the fluid, the transmission of cough high frequency vibrations to the body side member 12 is extremely effectively prevented.
