PURPOSE:To provide an economical vibration resisting device by constituting the device from a box type case housing a operative shaft therein, a slide frame horizontally slidable and two pressure chambers communicating to each other through a check valve. CONSTITUTION:Working oil O is put in a case 1 in which is fitted longitudinally slidably a slide frame 9. The case 1 is divided by a partition projection line 5 into two pressure chambers 14, 15 to form a narrow flow gap 17 for working oil between both chambers and control the working oil with check valves 20, 21. Thus, when the slide frame 9 moves horizontally, the volume of either of pressure chambers 14, 15 is increased, and oil flows through the flow gap while the flow is restrained by the flow resistance. Thus, this device can be installed stably and, since the box type case 1 contains the working oil O, has no possibility of oil leakage. The whole constitution is simplified and economized. |
