ルが挿抜出来る取外位置には回動出来ない。In the prior art, the handle is rotated 180 degrees from the fully open position so that the handle can be incorporated in the stopper body in a stoppered state with a simple structure. In this posture, the stopper body and the handle can be inserted and removed in the axial direction, and when the stopper body is rotated by a constant angle smaller than 90 degrees, the collar portion protruding from the handle shaft portion and the stopper body The handle is attached to the plug body main body 1 in a retaining state by vertical engagement with the annular protrusion protruding inward from the cylindrical portion at the upper end. Then, in this state, when a setscrew is screwed through the handle from the upper surface of the handle, the set screw and the plug body main body 1 are rotated by 90 degrees in both the clockwise and counterclockwise directions from the fully open position. However, the handle cannot be moved to a posture in which the handle is rotated 180 degrees from the fully opened position, that is, the handle is in a detachable position where the handle can be inserted and removed.

Then, it is inconvenient for those who do not expect this. The present invention has been made in view of the above points, and with a simple configuration, it is possible to assemble the handle and the stopper main body in a state in which the handle and the stopper main body are retained, and to prevent the inconvenience of accidentally opening the gas stopper. The task is to do.

The collar portion (3) can be vertically inserted into and removed from the annular protrusion (4) of the gas stopper body (1) in a posture rotated by 180 degrees from the fully opened position, and from the fully opened position. In the clockwise and counterclockwise 90-degree range, it is configured to engage in the retaining state in the vertical direction, and a part of the annular protrusion (4) has a first arcuate portion (4a) covering a range of 180 degrees or less. The tip portion (51) of the stopper (5) is urged in one of the vertical directions, and the turning radius of the tip portion (51) is larger than the inner diameter of the first arcuate portion (4a). An engaging portion (41) that is fitted in the axial direction by the urging force acting on the distal end portion (51) is provided at a position that is largely set and deviates from the first arcuate portion (4a).
A releasing piece (P) for releasing the engagement between the engaging portion (41) and the tip portion (51) against the urging force of the (51) is interlocked with the stopper (5) and the handle (H ), And at the closed position of the handle (H), the upper end of the release piece (P) protrudes from the upper surface of the handle (H).

As a result, the plug (2) and the handle (H) are locked in the closed position by the fitting engagement, and the upper end of the release piece (P) projects to the upper surface of the handle (H) to a certain extent. In this state, handle (H) and stopper (2)
To rotate the to the fully open position, push in the protrusion on the tip of the release piece (P). As a result, the tip end part (51) can be released from the engagement part (41) and can be rotated to the fully open position. When the handle (H) is rotated in the opening direction in this state, the tip end part (51) is released. The tip portion is located either in the axial direction with respect to the first arcuate portion (4a) or due to the relationship with the annular protrusion (4).
Since the (51) is in the disengaged state in the circumferential direction, it can be rotated to the fully open position.
