By the way, the operation handle 208 of the valve device 206 is mounted on the tank body 20.
2 attached to the side. For this reason, there is a problem that it is difficult to understand the direction of the switching operation between the large washing and the small washing.

In recent years, there has been a configuration in which a washing water tank is stored in a storage shelf, and a configuration in which a makeup panel is arranged between a toilet and a washing water tank to hide the washing water tank, thereby improving the design. Let me. In such a washing water tank,
Since the operation handle cannot be arranged on the side surface of the tank body, it is attached to the makeup panel.

However, when the operation handle is mounted on the makeup panel, if the operation handle is mounted in the center of the washing water tank, the operation handle is hidden by the toilet seat or the lid, and there is a problem that the usability is not good. . In such a case, if the operation handle is set apart from the center of the washing water tank and a configuration is adopted in which large cleaning and small cleaning are switched, the valve body of the valve device is tilted and opened and closed by the operation handle. In addition, it is not possible to adopt a configuration for switching between large cleaning and small cleaning, and only a cleaning operation for large cleaning is provided.

The present invention solves the above-mentioned problems of the prior art, in which an operation handle is provided at a position distant from the center of the tank body, and large and small cleaning can be switched with a simple configuration. An object of the present invention is to provide a flush water tank device for a toilet bowl.
