Can do.

  In addition, although the sanitary washing apparatus in this Embodiment set it as the structure which arrange | positions the main-body part 200 on the right side of the support plate 320, it is not restricted to this, As a structure which arrange | positions the main-body part 200 on the left side of the support plate 320 Also good. Moreover, it is good also as a structure which makes the main-body part 200 the independent structure instead of the structure which installs the main-body part 200 in the support plate 320, and installs the main-body part 200 in arbitrary places, such as a floor surface or a wall surface of a toilet room.

  Moreover, although the sanitary washing apparatus in this Embodiment used the copper water supply pipe 330 as a water supply channel, it is not restricted to this, The water supply pipe by another material may be sufficient. Moreover, as a water supply path of another structure, a water supply pipe is not used, a rib is formed in the lower surface of the upper plate 322 of the support plate 320, and a tunnel-like flow path is formed by joining the rib and the lower plate 321. A configuration in which a tunnel-like channel is used as a water supply channel may also be used.

  As described above, the sanitary washing apparatus according to the present invention can add a washing function to a commercially available toilet apparatus with a simple configuration, and thus can be applied to other simple water application devices.
