PURPOSE:To adjust the damping force of a buffer by utilizing a magnetic fluid and an electromagnet. CONSTITUTION:A magnetic fluid is mixed in an oil flow of a hydraulic buffer, and an electromagnet 12 is fixed to the outer periphery of a portion where the magnetic fluid passes a control portion thereof. The viscosity of the passing magnetic fluid is changed depanding upon the amount of a current applied to an exciting coil of the electromagnet 12 so as to change the speed of the running magnetic fluid. |
