<p><P>PROBLEM TO BE SOLVED: To solve the problem that, in a toilet bowl flushing tank device provided with a feed delaying mechanism and a flowing water discharge port, normal operation of the feed delaying mechanism is impeded by flowing water falling from the flowing water discharge port entering into a delaying tub of the feed delaying mechanism. <P>SOLUTION: A toilet bowl flushing tank device comprises: a ball tap device 22 provided with a feed valve 58, a float 28, and a connection arm 30 connecting the feed valve 58 and the float 28; a feed delaying mechanism 202 positioning the float 28 in a delaying tub 200, making water in the delaying tub 200 flow out through a small hole after a drain valve is opened to delay lowering of the water level in the tub 200, and delaying opening of the feed valve 58; and a flowing water discharge port 150 discharging flowing water for freezing prevention to make the flowing water flow down through the connection arm 30. In the toilet bowl flushing tank device, a water drip part 230 draining off the flowing water flowing down through the connection arm 30 and a water receiving member 216 are provided above the delaying tub 200 to lead the flowing water to the outside of the delaying tub 200. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
