[0002]

2. Description of the Related Art Generally, a water control valve for controlling tap water flowing inside a water main is installed in a water main for water supply. And the water main is usually buried underground. For this reason, water control valves are also buried underground. Further, since it is necessary to open and close the water control valve due to a water supply work or the like, the water control valve is installed inside a housing buried underground.

[0003] Conventionally, in order to operate the opening and closing of the water control valve, a lid of a housing is removed, and a valve body opening / closing tool having a long handle is inserted through an opening formed after the lid is removed. The valve opening / closing operation portion of the valve body is rotated by the valve body opening / closing tool. Therefore, in order to easily open and close a valve body buried deep underground, a water control valve operating tool is attached to a valve opening / closing operation portion of the valve body.

The water control valve operating tool includes a valve body operation base in which a fitting portion to be fitted to a valve opening / closing operation portion of a water control valve is integrally formed on a distal end side of a substantially rod-shaped shaft portion, An operating body attached to the base end side of the operation base and formed substantially in the same shape as the valve opening / closing operation portion of the water control valve; and an operation body inserted from the base end side of the valve body operation base and attached to the shaft of the valve body operation base. A valve body opening / closing tool is attached to the operating body, and when the operating body and the valve body operating base are rotated to rotate the valve opening / closing operation part of the water control valve, the operating body and the valve body operating base swing.

However, in this water control valve operating tool, in order to attach the steadying body to the valve body operating base, the base end side of the valve body operating base is inserted through the steadying body. If the operating body is formed integrally with the valve body operating base, it is necessary to get over the radially protruding flange formed on the operating body, so that the operating body is formed separately. For this reason, when rotating the valve opening / closing operation part of the water control valve to open and close the water control valve, a great force is applied to the connection part between the valve body operation base and the operation body, so that the durability is not sufficient. In addition to the problem that it is difficult to secure the valve body, there is a problem that the manufacturing cost increases because the valve body operation base and the operation body are formed by casting or the like.

In this water control valve operating tool, a fitting portion of a valve body operation base is fitted to a valve opening / closing operation portion of the water control valve, and a swing stopper is provided on a base end side of a shaft portion of the valve body operation base. In this configuration, the body is inserted and the steadying body is attached to the shaft of the valve body operating base, and the operating body is attached to the base end side of the valve body operating base. For this reason, there is a problem that the work of attaching the water control valve operating tool to the water control valve buried underground is complicated.
