Claims (1)

[Scope of Claim for Utility Model Registration] A ball (valve) having a through hole is airtightly and rotatably housed in the valve chamber of a valve body that is equipped with a through hole for connecting to gas piping, a tank, etc., through a seat. However, in the existing ball valve configuration in which the ball is rotated at a set angle by a spindle connected to the handle to open and close the valve, the spindle is divided into a ball-side spindle and a handle-side spindle, and the spindles are arranged on the same axis. A clutch mechanism is provided at the upper end of the ball-side spindle and the lower end of the handle-side spindle, which are opposed to each other, for interlocking the two spindles. The set angle of the spindle on the handle side rotates freely, and the set angle of both spindles rotates at the same time (valve opening/closing rotation).In addition, the set angle of the handle side spindle and the idle rotation angle of the handle side spindle are set at a position corresponding to the handle circumference on the handle mounting surface. A ball valve with a clutch mechanism, characterized by an indication that guides the rotation angle of both spindles (valve opening/closing angle).
