ウンを計れる。As mentioned above, the present invention consists of a cock body that houses a closure and has one opening closed with a lid, and a leg that has a support piece that faces the lid with a gap therebetween and that has an end fixed to the lid. A supporting metal piece integrally formed with the support piece, and a locking part between the support piece and the lid body, which is supported through the support piece and the lid body so as to be rotatable and slidable in the axial direction, and is always biased by a spring in the direction of separation of the closing member. an operating shaft for driving the closing member; a piezoelectric ignition device provided on the lid on one side of the opening of the support fitting and having a protruding hammer pin; A cam plate that is mounted so as to move in conjunction with the rotating direction of the operating shaft, is biased toward the locking portion by a spring, and has a pawl that engages with the hammer pin when pushing and turning the operating shaft. In this case, an engaging part is integrally provided on the side opposite to the claw part of the cam plate and the operating shaft, and a part of the stopper is bent toward the lid body on the other opening side edge of the support bracket of the support piece. A part of this stopper has a hanging side that prevents the engaging part from rotating in the ignition operation direction when the operation shaft is not pushed in, and an inclined side that slopes from the top of this hanging side toward the ignition operation direction of the operation shaft. The cam plate is mounted so as to be tilted by the force applied to the retaining portion in the direction of the lid body, and the cam plate for ignition and the support metal fittings that have been provided in the past are replaced. Since the rotation of the operating shaft is regulated using the rotation of the operating shaft, it is possible to improve assembly workability and reduce costs without requiring a member such as a leaf spring dedicated to rotation regulation.

してしまう欠点がある。The above-mentioned rotation regulation may be achieved by using the claw part of the cam plate and providing a part of the stopper on the side edge of the support piece on the ignition device side, but in this case, when the cam plate returns to rotation, the claw part becomes part of the stopper. There is a risk that the gas cock will be pushed downward and displaced and hit the ignition device, making it impossible to return smoothly.In order to solve this problem, the height of the support piece and the height of the cam plate are increased, but the gas cock becomes larger. There is.

ガスコックを小型化できる効果を奏するものである。In this regard, according to the present invention, the retaining part of the cam plate is formed on the side facing the claw part by sandwiching the operating shaft, and the cam plate is attached to the operating shaft so as to be tiltable, so that the cam plate can be rotated. At the time of return, the cam plate is tilted and the claw side is displaced upward, so that the claw does not hit the ignition device, allowing smooth return, and the gas cock can be made smaller.
