The opening / closing mechanism of the fire hydrant valve 109 by the opening / closing lever 10 is, as shown in FIG.
Are coupled to the opposing pulley 12 so that the opening / closing lever 10 rotates back and forth coaxially with the center of rotation of the opposing pulley 12. Then, pulling the opening / closing lever 10 causes the opposing pulley 12 to rotate at the same time. A pair of substantially ring-shaped wires 11 is hung on the opposed pulley 12, and the wire 11 is engaged and fixed to the opposed pulley 12 at one point. Due to this fixation, the wire 11 is rotated by the same amount as the counter pulley 12 is rotated.

On the other hand, the wire 11 passes through a tube 13 having both ends fixed to a fixing plate 19 and is hooked on an interlocking pulley 14 which is interlocked with a valve element of a fire hydrant valve 109.
Is stretched between the interlocking pulley 14 and the opposing pulley 12. Similarly to the opposing pulley 12, the interlocking pulley 14 is also engaged and fixed at one point with the wire 11, and the interlocking pulley 14 is rotated by the same amount as the rotational movement of the wire 11. Along with the rotation of the interlocking pulley 14, a coaxially interlocking valve element opens the fire hydrant valve 109 (not shown in detail).
