The stepped portion 20 is disposed between the upper portion 23 and the lower portion 24 so as to be substantially horizontal (horizontal or an acute angle than horizontal may be formed) when the toilet seat 10 stands. The step portion 20 has substantially the same cross-sectional shape in the entire left and right direction.

Next, the drop of the splash adhering to the back surface of the toilet seat 10 will be described.
Splashes such as urine and washing water that has washed the buttocks are particularly likely to adhere to the range indicated by the oblique lines in FIG. 5 (the range corresponding to the upper end opening of the toilet bowl 3). In other words, the splash of cleaning water or the like is likely to adhere to a portion of the back surface of the toilet seat 10 that does not face (overlap) the toilet body 1 or the front wall 39. The splash adhering to the back surface of the toilet seat 10 descends along the back surface of the toilet seat 10 as the toilet seat 10 stands and reaches the inclined portion 18. Some of the splashes that have reached the inclined portion 18 fall off the inclined portion 18 due to their own weight. Moreover, the splash which reached the level | step-difference part 20 along the inclination part 18 leaves | separates from the level | step-difference part 20 with dead weight, and falls to the toilet bowl part 3 as shown by the arrow of FIG. Thus, since the droplet falls to the toilet bowl 3 without reaching the rear end portion of the toilet seat 10, it is not necessary to wipe off the splash.

Next, operations and effects of the embodiment configured as described above will be described.
The toilet seat 10 according to the present embodiment can be rotated between a lying state and an upright state on the upper side of the toilet bowl 3, and in the upright state, the toilet seat 10 is continuous in the lateral direction on the back surface of the portion located below the opening 11. Step portion 20 is provided. According to this configuration, since the splash that has traveled down the back surface when the toilet seat 10 stands up is cut off at the stepped portion 20 and dropped, the splash adhering to the back surface can be prevented from entering the hinge portion 15 or the like.

  Further, the step portion 20 is formed in a range at least equal to or larger than the width of the upper end opening of the toilet bowl portion 3. According to this configuration, since the step portion 20 corresponds to the portion where the splash is most likely to adhere, it is possible to effectively prevent the splash adhering to the back surface from entering the hinge portion 15 or the like.

  In addition, the stepped portion 20 is provided in the inclined portion 18 that is inclined downward toward the rear in the standing state. According to this configuration, since the splash that has traveled down the back surface when the toilet seat 10 stands up more easily falls, it is possible to more reliably prevent the splash adhering to the back surface from entering the hinge portion 15 or the like.
