。このため部品点数及び工程数が多く、組立が複雑とな
り、また、コストが高くなる傾向があった。Conventionally, in an open stay made by filling a gas in a tube into which a piston is slidably fitted, a separately formed cap 1' is fixed to the open end of the tube 1 by equal pressure by welding, as shown in Fig. 1. A hole was made at the tip of 1 to inject gas, and a plug 7 was press-fitted or welded into the hole to seal it. For this reason, the number of parts and steps is large, the assembly is complicated, and the cost tends to be high.
本発明はこれらの問題を解決するためになされたもので

て説明する。In the present invention, one end of a tube is sealed with a piston front guide, and the other open end is spun to form a convex protrusion with a gas filling hole inside, and a plug or joint fitting is fitted into this gas filling hole. At the same time, the end of the tube thus formed is held in a sealed manner between the positive and negative electrodes of the welding device, and gas supplied from outside the welding device is injected into the tube through the gap between the gas filling hole and the plug. After that, the plug is welded to seal the gap.Examples of the present invention will be described below with reference to the drawings.

ものと変るところはない。In the gas-filled shock absorber, a piston 2 is slidably fitted inside a tube 1, a piston rod 3 is pulled out from one end 1m of the tube 1, and the end is sealed with a rod guide and a seal 4. The structure and assembly of these components are the same as the conventional ones.

いる。The present invention relates to a method for assembling a shock absorber by filling gas from the other end of the tube 1 constructed as described above.First, the other end 1 of the tube 2 which is in an open state is
b is subjected to spinning processing and formed into a convex protrusion 6 having a gas filling hole 5 therein as shown in FIG. The convex protrusion 6 is made to protrude outward in order to facilitate and ensure welding of a plug 7 or join 11 (to be described later), and is formed so that the wall thickness becomes thicker toward the tip. In addition, due to the spinning process of the gas hole 5Fi formed inside the convex protrusion 6, uneven wrinkles are formed on the inner circumferential surface and end surface thereof.

る間隙が形成されている。Next, the plug 7 is fitted into the gas filling hole 5 of the convex projection 6 of the tube 1. This plug 7 is preferably provided with a flange as shown in the figure, so that the flange surface is engaged with the tip of the protrusion 6. As mentioned above, the end surface and inner peripheral surface of the convex protrusion 6 are rough due to the spinning process, and uneven wrinkles are formed, so when the plug 7 is fitted into the gas filling hole 5, the hole is A gap is formed between the fitting surfaces of the plug 5 and the plug 7 due to the wrinkles.

When gas is supplied from the outside to the gas chamber 10 surrounding the convex protrusion 6 through the gas filling plug 11 of the welding machine, the gas flows through the hole 5 of the convex protrusion 6 and the plug. 7 into the tube 1. After injecting a predetermined amount of gas into the tube 1, current is passed through the electrodes 9a and 9b of the electric resistance welding machine 8 to weld the plug 7 to the convex protrusion 6, causing molten metal to flow between the plug 7 and the gas filling hole 5. The gap is filled, thereby welding the plug 7 and sealing the gas filling hole 5 at the same time.

はシールリングである。Although FIG. 3 shows an example in which only the plug 7 is welded to the gas filling hole 5, it is also possible to superimpose a joint 11 on the plug 7 and weld it at the same time, as shown in FIG. 4. Furthermore, as shown in FIG. 5, it is also possible to seal the joint 11 by directly welding it to the protrusion 6. In this case, it is desirable to form the joint 11 integrally with the plug 7 as shown in the figure. In the figure, 12 is an insulator, 13 is a stopper, 14
is a seal ring.

程を著しく短縮することができる。According to the present invention, since the tip of the tube is directly formed into a cap shape by spinning, forming and welding of the cap as in the conventional method is not necessary, and since the tip is formed into a convex projection, it can be used as a plug or joint. Welding becomes easy and reliable. Furthermore, since gas injection and welding and sealing of the plug or joint can be performed almost simultaneously, the manufacturing process can be significantly shortened.
