In the state, as shown in FIG. 1, the piston 28 is located at a substantially central position of the cylindrical portion 26 in the X direction. In this state, the earthquake causes the vibration-isolating structure 150 to vibrate in the horizontal direction, so that the piston 28 moves in the X direction by the piston rod 29 in the first direction 117231.doc -16 - 200827588 in the X direction via the piston rod 29 as shown in FIG.

On the other hand, the pressure reduction of the liquid a in the chamber 3 is transmitted to the chamber 54 via the orifice 14, and the liquid a in the chamber 54 is also depressurized. When the piston 28 first moves in the XI direction, even if the piston 28 moves to the vicinity of its maximum displacement position (D=+Max), the main control valve body 75 is not moved to the B2 direction until the center passage 91 is opened, so The movement of the piston rod 29 from the substantially central position (D=0) of the cylindrical portion 26 to the maximum displacement position (D=+Max) of the piston 28 in the XI direction causes the vibration energy absorbing device 1 to generate the orifice 7 The reaction force (resistance) R shown by the curve 121 in Fig. 1A is supplied to the piston rod 29.

When the valve seat member 57 moves in the B1 direction, the liquid a is introduced into the chamber 59 from the large diameter passage 93 through the hole 68, so that the chamber 59 does not become a negative pressure. As shown in Fig. 8, the piston 28 moves from the substantially central position (d = 〇) of the cylindrical portion 26 toward the X2 direction, and reaches the maximum displacement position (D == _Max) in the X2 direction. The position (D=-Max) starts moving again in the XI direction, q the liquid A of the chamber 4 is pressurized, and on the other hand, the liquid A of the chamber 3 is decompressed, thereby mainly utilizing the liquid A passing through the chamber 58 of the check valve 16. The pressurization and the depressurization of the liquid A through the chamber 54 of the orifice 14 cause the valve body 51 and the valve seat member 57 to move in the direction, and as shown in Figs. 1 and 8, the main control valve body 75 is again Located in the central passage 91, the central passage 91 is closed to prevent the large-diameter passage 92 and the large-diameter passage 93 from communicating via the central passage 91 and the expansion-diameter passages 94 and 95, and the flow of the liquid A to the chamber 3 side of the chamber 4 passes through the hole again. The port 7 is instead of the central passage 91, so that in the movement of the piston 28 from the maximum displacement position (D=-Max) in the X2 direction to the XI direction, the vibration energy absorbing device 1 produces the aperture 7 in the curve 124 of Fig. 1 117231.doc -19- 200827588 The reaction force R provides 仏, 壬耷 / tongue plug in the valve seat member 57 to move in the direction of 32, liquid A white - 丄, ^ Π to 59 导出 is derived from the hole 68 and to the large diameter channel 93.
