Description of the Related Art In general, a toilet seat device for washing has a nozzle mechanism equipped with either or both of an anus washing nozzle and a bidet washing nozzle in a housing for hygienically washing a human body part after use. The washing water piping structure to the mechanism is composed of an external water guiding system connected to a water supply source such as a water pipe and an internal water guiding system connected to the nozzle mechanism in the housing. The external water transfer system has a method of distributing and using the wash water from the water supply source together with the low tank, and a method of pumping the wash water stored in the low tank and the like and using it. When the former method is adopted, a water pressure adjusting mechanism such as a pressure adjusting valve is provided in the internal water guiding system. In general, the internal water guiding system is provided with a wash water tank for temporarily storing wash water.

By the way, regardless of whether tap water or stored water in a low tank is used as the cleaning water, rust dust, pebbles, and other solid matter may be mixed in the cleaning water of these water supply sources. If such solid matters enter the internal water guiding system, there is a possibility that the nozzles may be clogged in the nozzle mechanism or the valve operation of the water pressure adjusting mechanism may be defective. Therefore, as shown in FIG. 6, a strainer unit using a wire mesh as a filter is connected to an external water guiding system in the conventional flush toilet seat device.

FIG. 6 shows a conventional example of the connection form of the strainer unit (specification of Japanese Utility Model Laid-Open No. 3-25669). In this conventional configuration, the low tank 1 is installed adjacent to the wall surface W on the back side of the toilet room, and is placed on the rear portion of the toilet 2 between the toilet 2 and the low tank 1 installed in front of the low tank 1.
