DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. This embodiment relates to a toilet seat device used in a human body local cleaning device. As shown in FIG. 1, a base cover 4 having a built-in human body cleaning device is provided on the upper surface of the rear end of the toilet 1. The base cover 4 has a U-shape that opens to the toilet 1 side. A pair of hinges are provided at the rear ends of the toilet seat 2 and the toilet lid 3 disposed on the upper surface of the toilet 1, and the hinges allow the toilet seat 2 and the toilet lid 3 to have a U-shape of the base cover 4. Are rotatably supported on the inside of the opposing surface of. A rubber leg is attached to the lower surface of the toilet seat 2 (FIG. 3). In this embodiment, two front legs 7 are mounted on the front side and two rear legs 8 are mounted on the rear side, respectively, so as to cushion the impact between the toilet seat 2 and the toilet 1.

Next, the hinge portions of the toilet seat 2 and the toilet lid 3 will be described. FIG. 2 is a sectional view taken along the line BB of FIG. A pair of long holes 2a (only one side is shown in FIG. 2) are formed on both sides of the rear end portion of the toilet seat 2, and the cross section of the long hole 2a is shaped like a long hole in the vertical direction. Further, a pair of hinge holes 3a (only one side is shown in FIG. 2) are formed on both sides of the rear end of the toilet lid 3, and the hinge hole 3a is different from the elongated hole 2a.
Its cross section is circular.

A hinge shaft 5 is inserted into the elongated hole 2a and the hinge hole 3a. The diameter of the hinge shaft 5 is substantially the same as the hinge hole 3a of the toilet lid 3, and the hinge shaft 5 is slidably fitted in the hinge hole 3a. Further, an elastic body 6 made of resin is disposed between the hinge shaft 5 and the elongated hole 2a. Elastic body 6
Urges the toilet seat 2 upward by urging the long hole 2a upward. One end of the hinge shaft 5 has a flange portion 5a
Is formed, and the diameter of the flange portion 5a is larger than the diameter of the elongated hole 2a in the longitudinal direction. The other end of the hinge shaft 5 projects from the hinge hole 3a, and is fitted into a hole 4a formed in the base cover 4. A washer 9 is fitted to the end of the hinge shaft 5 that penetrates the hole 4a, and an E-shaped retaining ring 10 is further fixed to the outside to prevent the washer 9 from falling off. The washer 9 and the flange 5a
Thus, the hinge shaft 5 is positioned so as not to move in the left-right direction. Thus, the toilet seat 2 and the toilet lid 3 are pivotally supported by the base cover 4 by the hinge shaft 5. In the toilet seat device of the present embodiment, the elastic body 6 urges the toilet seat 2 upward, and when the toilet seat 2 is lowered on the toilet 1, a slight gap is formed between the rear leg 8 of the toilet seat 2 and the toilet 1. a (FIG. 3).

Next, the operation of this embodiment will be described with reference to FIG. When the toilet seat 2 is lowered onto the toilet 1, the front legs 7 of the toilet seat 2 come into contact with the toilet 1 and stop. At this time, as described above, the elastic body 6 includes the upper end of the inner edge of the elongated hole 2a and the outer peripheral of the hinge shaft 5 .
Between the upper biases upward the seat 2 at all times. When the user sits on the upper surface of the toilet seat 2 in this state, the toilet seat 2 is urged downward, and the elongated hole 2 a of the toilet seat 2 moves downward along the outer periphery of the hinge shaft 5 against the urging force of the elastic body 6. Go to In this way, the rear end of the toilet seat 2 drops, and the rear leg 8 also comes into contact with the toilet 1, so that the toilet seat 2 is stabilized with respect to the toilet 1 without imposing a load on the hinge portion at the rear end. Then hinge

Never.

When the toilet seat 2 is opened, the toilet seat 2 is
Around the center. The elastic body 6 disposed between the elongated hole 2a and the hinge shaft 5 urges the toilet seat 2 not to move in the vertical direction of the elongated hole 2a. As described above, since the rattle 2 does not rattle even when the toilet seat 2 is rotated, the toilet seat 2 can be smoothly opened and closed.

The present embodiment is characterized in that the elastic body is disposed between the elongated hole and the hinge shaft to constantly bias the toilet seat upward. Although the case where the shaft is fixed to the base cover has been described, according to the present invention, the same effect can be obtained even if the elongated hole is formed in the base cover and the hinge shaft is fixed to the toilet seat. Further, the elastic body 6 is not limited to a resin, but may be made of a metal.
