It moves up and down between the ascending position (the position shown in FIG. 1B) which has not been moved. By raising the functional unit 12 to the raised position, the user can wipe the rear side of the upper surface unit 16 to clean it. The functional unit 12 may be lifted and lowered by being manually lifted by the user.

  FIG. 3 is a perspective view of the toilet body 10. FIG. 4 is a top view of the toilet body 10. On the rear side of the upper surface portion 16, a concave portion 22 that is recessed downward is formed. The recess 22 is formed at a position avoiding the water passage 44 for supplying the wash water to the toilet bowl 14 from a water supply source such as a water pipe or a wash water tank (both not shown). Further, the recess 22 is formed at a position avoiding above the cavity 46. Conversely, the cavity 46 is formed at a position avoiding the lower part of the recess 22. In this embodiment, the recess 22 is provided above the rear end of the toilet bowl 14, and there is no cavity 46 below the recess 22, that is, between the recess 22 and the toilet bowl 14. More specifically, the cavity 46 does not exist between the flat bottom surface 28 (described later) of the recess 22 and the toilet bowl 14.

  The recessed portion 22 is recessed below the front and side portions of the upper surface portion 16 of the toilet bowl 14. The recess 22 is formed to be larger than the protrusion 12a so as to accommodate the protrusion 12a described later. In the present embodiment, the recess 22 extends along the opening 40. That is, the recess 22 is slightly curved along the opening 40 in a plan view. In the present embodiment, recess 22 is formed so that its front side faces opening 40. That is, the recess 22 communicates with the opening 40. It can be said that the entire front surface of the peripheral surface of the recess 22 is open. Further, in the present embodiment, the recess 22 has an inverted trapezoidal shape in a front view.

  The recess 22 has a first side surface (right side surface) 24, a second side surface (left side surface) 26, a bottom surface 28, and a back surface 30. The bottom surface 28 is flat and has a shape elongated in the left-right direction. The bottom surface 28 may be formed such that the length thereof in the left-right direction is longer than the width of the toilet drainage channel 18 in the left-right direction. Further, the bottom surface 28 may be formed such that the length thereof in the left-right direction is longer than 1/2 times the maximum width of the opening 40 in the left-right direction.

  The first side surface 24 and the second side surface 26 are provided so as to be separated from each other in the left-right direction, and are inclined so as to approach each other toward the lower side. The first side surface 24 and the second side surface 26 are formed to be flat and have relatively gentle slopes. Preferably, the first side surface 24 and the second side surface 26 are formed such that the angle formed with the horizontal plane is 45° or less. In the present embodiment, since bottom surface 28 is substantially parallel to the horizontal plane, first side surface 24 and second side surface 26 are formed such that the angle formed with bottom surface 28 is 45° or less.

  The back surface 30 is formed such that the angle formed with the horizontal surface is 10° or more and 90° or less. In the present embodiment, since bottom surface 28 is substantially parallel to the horizontal plane as described above, back surface 30 is formed such that the angle formed with bottom surface 28 is 10° or more and 90° or less. In the present embodiment, the back surface 30 is formed so as to be substantially orthogonal to the bottom surface 28.

  The back surface 30 has a shape in which the rear end of the opening 40 is offset. Specifically, the back surface 30 is curved so as to be convex toward the rear side. Here, when forming the toilet body 10 from a ceramic material, excess ceramic material is discharged to form the cavity 46 in the upper surface 16 and the like. In the present embodiment, the rear side of the toilet body 10 is lifted to drain excess ceramic material from the front side. At this time, since the back surface 30 is curved so as to be convex toward the rear side as described above, no ceramic material remains behind the back surface 30.
