It was not suitable for the device.

When connecting a cylinder filled with a high-pressure gas or the like to be filled with a filling device, it is necessary to prevent the high-pressure gas, which is the content, from leaking to the outside. Since it is required to maintain it completely, thick and thick plain washers and elastic members were used for packing. Therefore, when the members are frequently attached and detached, a separate tool or a strong force is required every time the members are separated from each other.

At the same time, when removing the cylinder, the cylinder itself is rotated to release the screwed state. However, if the screw is strongly screwed in order to maintain the joint state as described above, it is difficult to remove and filling The connection between the container and the connection body in which the gas leakage prevention valve member was inscribed was accidentally disconnected, and the residual gas in the cylinder was ejected as it was to the outside. There is also a risk of being lost. Although it is a small amount of residual gas, it is necessary to take some measures especially for those such as CFCs that are environmentally unfriendly to be released into the atmosphere.

A locking portion 3c is provided between the thread 3a and the thread 3b for distinguishing between the thread 3a and the thread 3b. The locking portion 3c is configured to be slightly thicker than the axial thickness of the thread 3a and thread 3b of the connection body 3.

In addition, this connecting body 3 is internally provided with a cavity for sending the high-pressure gas sealed in the cylinder 2 to the filling device 1, and gas leakage is caused at the end face in the connecting direction with the filling device 1. A valve member 3d for prevention is provided inside. The washer 4 according to the present invention is fitted into the connector 3. That is, as shown in FIG. 1, the washer body 4a of the washer 4 is provided with the opening 4b for fitting into the connecting body 3 as described above, and the opening 4b is the opening 4b. Insert it into the screw foot. This washer 4 has leg bases 4c in the horizontal direction on the outer peripheral edge of the washer body 4a. The leg base 4c is provided in a shape protruding in the horizontal direction with respect to the plane of the washer body 4a, and is provided with a total of three positions, that is, three leg bases 4c.

The leg base 4c is provided with a leg body 4d in a direction horizontal to the axial center of the connector 3 when the connector 3 is fitted into the opening 4b of the washer body 4a. That is, a leg base 4c is formed by projecting from the washer body 4a in parallel with the horizontal plane of the washer body 4a, and then the leg body 4d is formed by bending the leg base 4c by about 90 degrees. It itself has a substantially L-shape. The tip 4e of the leg body 4d thus formed is inclined outward from the axial direction of the connector 3.

Therefore, as shown in FIG. 1, the basic form of the washer 4 according to the present invention is that the washer body 4a has the opening 4b and the substantially L-shaped leg portions 4c and 4d.
