PURPOSE:To improve the buffer effect of a damper and stabilize its performance by forming the damper to cause three actions, namely, frictional resistance due to packings, viscous resistance due to an adhesive silicon oil poured into a gap between fitted parts and pneumatic pressure is an air chamber, to function effectively. CONSTITUTION:A base body 1 is provided with a flow hole 1b to connect a cylinder wall 1a with a cylinder. A piston 2 is provided with a cylinder engaging part 2a fitting in said cylinder wall 1a, a primary packing groove 20 formed in the circumferential direction of said engaging part 2a, an engaging part 2b in the flow hole 1b, a secondary packing groove 2d formed is the circumferential direction of a flow hole engaging part 2b and an engaging groove 2e for a buffered member. The piston 2 is moved according to impulse force onto the buffered member. In this case, frictioal resistance due to both packings 3, 4, viscous resistance due to a silicon oil or the like applied between the cylinder wall 1a and the cylinder engaging part 2a and pneumatic pressure in an air chamber 5 are therefore generated. |
