[0036]
Further, the detection device for detecting that the toilet lid 4 is closed fits the thin indicator ring 21 at the boundary between the different diameter portion 13a and the circular shaft portion of the braking support shaft 13 of the opening / closing speed suppressing means 12. Since the limit switch 24 is provided on the outer surface of the top of the mounting member 14, the dimensions of the braking support shaft 13 and the opening / closing speed suppressing means 12 in the axial direction can be made little or not large. There is no need to increase the width of the support portion 6b. Thus, the warm water washing toilet seat apparatus 1 can be made compact so as to fit within a predetermined width dimension. Further, since the rotation position indicating piece 23 is provided by fitting the indicating ring 21 to the brake support shaft 13, the existing opening / closing speed suppressing means 12 can be used as it is and can be configured at low cost. .
[0037]
Further, a seal flange 22 is provided on the outer periphery of the indicating ring 21 so as to project close to the inner wall surface around the brake support shaft through hole 20 formed in the main body cover 2. It is possible to prevent water from entering the main body cover 2 from the hole 20 and causing trouble, and the seal flange 22 and the rotation position indicating piece 23 are integrally formed at the same time. Can be further improved.
[0038]
Further, since the lead wire 26 extended from the limit switch 24 is engaged with and held by the locking piece 27 provided on the outer surface of the mounting member 14, an unexpectedly large external force acts on the lead wire 26. Even in this case, it is possible to prevent the connection portion of the lead wire 26 from being damaged or broken and to prevent the lead wire 26 from getting in the way at the time of assembly, thereby improving workability.
[0039]
In the description of the above embodiment, an example in which the limit switch 24 is used as the detection means has been shown. However, a reed switch may be used by configuring the indicator ring 21 with a magnetic material such as a punched part of a stainless steel plate having magnetism. In addition, other optical switches or the like can be used. Moreover, although the example which attached the detection means to the outer surface of the attachment member 14 was shown, you may arrange | position in the receiving part 16 of the attachment member 14 or the main body cover 2. FIG. Further, the rotational position indicating piece 23 and the seal flange 22 may be integrally formed on the braking support shaft 13.
