PURPOSE:To provide good vibration damping force with a simple structure by forming a coil spring with a pipe material, opening one end of the space in the pipe to an upper liquid chamber, and opening the other end to a lower liquid chamber through a partition plate to form an orifice passage. CONSTITUTION:A container-shaped upper housing 1, a lower housing 2, and a side plate 3 are provided with openings faced to each other, and a rubber elastic body 4 is connected between the side wall 11 of the upper housing 1 and the side plate 3. The lower section of a partition plate 6 is sealed with a rubber film 5, and the inside is divided into upper and lower liquid chambers A, B. A coil spring 7 is provided in the liquid chamber A between the partition plate 6 and the upper housing 1. The coil panel 7 is made of a pipe material, one end of the space 7a in the pipe is opened to the upper liquid chamber A, the other end is opened to the lower liquid chamber B through the partition plate 6 to form an orifice passage, and good vibration damping force is generated. |
