PURPOSE:To simplify gas charging work and suppress gas leak by drilling gas charging holes which communicate when gas is charged and which are positioned on different stages on assembly, onto a damper and a cover member fitted onto the inner periphery of the edge part of the damper case. CONSTITUTION:A cover member 8 is inserted from the lower part into a damper case 2, and a gas charging hole 9 formed onto the cover member 8 is allowed to communicate to a gas charging hole 10 formed on the damper case 2, and gas is charged into a gas chamber S through both gas charging holes 9 and 10. After a prescribed quantity of gas is charged, the cover member 8 is slided upward and set to an assembly position, and the communication between the both gas charging holes 9 and 10 is cut-off. At last, the peripheral edge of the lower edge part of the damper case 2 is bent inwardly for tightening, and the cover member 8 is fixed. |
