PURPOSE:To absorb vibration certainly even in the condition where a force in the direction intersecting the axis is applied. CONSTITUTION:The ends of an outer cylinder 16 and an inner cylinder 14 are tied over by resilient pieces 16, 22 to form a liquid chamber 26, in the middle of which in its axial direction, ring-shaped plates 28, 30 are installed with a certain gap reserved, and a moving plate 32 in ring form is pinched by these two plates 28, 30 movably in the radial direction. The inner dia. of this moving plate 32, dimension D, shall be such that liquid receives a certain resistance when it passes through an orifice 34 formed between the inner cylinder 14 and the moving plate 32, while the width of the plate 32, dimension W2, be equal to or below the width of the ring-shaped plates 28, 30, dimension W1. Because the moving plate 32 is mobile in the radial direction, the inner cylinder 14 and moving plate 32 will never touch strongly even though the inner and outer cylinders 14, 18 make relative movement in the radial direction, and thus motion of inner cylinder 14 will not be hindered. |
