Abstract
A stop valve for a gas tank is provided which achieves favorable sealing performance by inhibiting rotation of a sealing member attached to a valve element. A passage is formed inside a valve body, and a valve seat is provided in the passage. The valve element which is engaged and disengaged from the valve seat is slidably inserted to a sliding hole bored in the valve body. The annular sealing member is arranged in sliding contact with the outer peripheral surface of the valve element and the inner peripheral surface of the sliding hole. A screw hole connecting to the sliding hole and coaxial thereto is provided in the valve body. A rotating operation member having a male screw is rotatably screwed into the screw hole from the outside of the valve body. One end of the rotating operation member is made to abut the valve body.
