BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush water tank device for an automatic flush toilet capable of automatically supplying flush water from a flush water tank fixed to a toilet.

[0002]

2. Description of the Related Art Generally, a stool-type flush toilet having a specification in which a flush water tank is set up and fixed at a rear portion thereof is used. On the other hand, sanitary washing devices having a local washing function have come to be widely used in recent years, and as such electric devices are incorporated in toilets, flush water for toilets can be automatically supplied. Some have been developed.
The present applicant has already proposed this automatic washing water tank device, for example, in Japanese Patent Application No. 62-275088 (Japanese Patent Application Laid-Open No. 1-116123). This has a structure in which a drain valve for opening a flow path to a toilet is connected to a drive device, and the drive device is operated by a switch to automatically supply water.

A driving device provided in the washing water tank device is fixed to an outer side wall of the tank and has a rotary solenoid built therein as a driving source. Then, the output shaft of the rotary solenoid is protruded from the driving device into the tank, a lever is fixed to the tip of the drive shaft, a ball chain is connected between the lever and the drain valve, and the chain is pulled up according to the rotation of the output shaft. By opening the drain valve.

[0004] Due to such a structure, a hole for passing the output shaft is required on the side wall of the tank, and a proper seal is required for the drive unit in preparation for leakage of washing water from the hole.

[0005]

However, the conventional driving device does not have a special sealing structure for the surroundings of water, but is a general electric component whose functional portion is covered with a cover. Absent. For example, a simple structure is adopted in which the cover is made of metal, is fitted on the outer periphery of the function part, and the cover is integrated with the function part by swaging.

When such a cover is caulked and integrated with the functional part, if the processing accuracy is poor, a gap may be formed on the fitting surface between the cover and the functional part, and it is hard to say that the sealing measures are perfect. . Further, even if the infiltration of water into the inside of the drive unit can be prevented, the cover and the functional unit are exposed to the leaked water, which may cause an electric leakage or the like due to corrosion.

[0007] The problem to be solved in the present invention is to enable the drive unit to protect the leaked water from the tank without taking it.

[0008]

According to the present invention, there is provided a flush water tank provided in a toilet body and provided with a drain valve body for opening and closing a flow path to a ball of the toilet body, and the drain valve body is linked. And a driving device for opening and closing by an electric driving means,
A washing water tank device in which a housing of the driving device is fixed to a side wall of the washing water tank, wherein a spacer is provided on a surface of the housing facing a side wall of the washing water tank, and a gap is provided between the side wall and the spacer. Further, the spacer is formed larger than the outer shape of the housing.

[0009]

Since the spacer has a gap between the housing of the drive unit and the side wall of the washing water tank, a hole or the like is formed in the side wall of the washing water tank for passing an output shaft of the drive unit or a bolt for fixing the housing. If the distance is included in the spacer, water leaked from the hole does not wet the housing. Further, since the housing itself is separated from the side wall of the washing water tank, water leaked from the hole flows down the side wall without reaching the housing.
