動することはなく、それに一体の弁体７６が管体８０内の流路を開閉することはない。 The operation will be described below. At the time of locking shown in FIG. 3, each of the latch balls 42 located outside the storage groove 32 of the inner cylinder member 7 is engaged with the inner surface 5 of the cylinder lock cover member 10.
The cylinder lock 5 is positioned so as to be locked to 4, and the cylinder lock 5 is urged to the front side by pushing the rear surface of the outer cylinder member 8 against the tip of the operating pin 23 urged by the coil spring 22 of the operating cylinder member 3. .. Further, in this state, each of the latch balls 24 located in the mounting hole 21 is located at a position facing the storage groove 29 of the inner cylinder portion 7 of the cylinder lock 5. Each of the latch balls 24 does not engage with each of the engaging grooves 47 of the tubular outer fitting member 10 by entering the storage groove 29, whereby the tubular outer fitting member 10 and the operating tubular member 3 in the rotational direction thereof. I'm leaving. Therefore, in the locked state, even if the operation handle 70 is rotated, the tubular outer fitting member 10 "idle" and the operating cylinder member 3 does not rotate, so that the operating rod 72 does not rotate and moves horizontally. The valve body 76 integrated with the valve body 76 does not open or close the flow path in the pipe body 80.

し、筒状外嵌部材１０の内面の係合溝４７に係合する状態となる。 In the locked state shown in FIG. 3, the key 60 is inserted into the key insertion hole 2 of the inner cylinder member 7 of the cylinder lock 5.
When inserted from 8 and rotated, the ridge 30 is disengaged from the engaging groove 41 of the outer cylinder member 8 and the inner cylinder member 7 is rotated, so that the latch balls 42 are opposed to each other as shown in FIG. It is possible to enter each of the storage grooves 32 of the inner cylinder member 7 located at the center. When the outer cylinder member 8 is pushed by the operating pin 23 in this state, the outer cylinder member 8 is disengaged from the engaging surface 54 of each of the latch balls 42 by entering each of the storage grooves 32, and the cylinder member. The whole of 5 moves forward. Along with this movement, the storage groove 29 of the inner cylinder member 7 also moves forward, so that the latch ball 24 there is pushed out together and protrudes outward from the inside of the mounting hole 21, and the inner surface of the tubular outer fitting member 10 It is in a state of engaging with the engaging groove 47 of.

It is fixed in the direction of rotation and cannot "idle". In this state, when the operation handle 70 is rotated, the operating cylinder member 3 rotates together with the tubular outer fitting member 10, whereby the operating rod 72 rotates and the screw portion 90 and the screw portion 96 are screwed together. The operating rod 72 moves horizontally, and the valve body 76 integrated with the operating rod 72 also moves horizontally in the pipe body 80 to open and close the flow path.
