  As illustrated in FIG. 7, when the cover 42 is in the closed state, the cover 42 contacts the upper surface of the casing body 41 and covers the upper surface portion of the casing body 41 and the functional device 5. The engaging portion 8 of the cover 42 is housed in the recess 6 of the casing body 41, and the protrusion 9 of the engaging portion 8 is located at the lower end 7 b of the guide groove 7. Since a circular concave step S having a deeper groove depth is formed at the lower end 7b of the guide groove 7, the protrusion 9 of the engaging portion 8 is fitted into the circular concave step S and stably held. Yes. When the protrusion 9 of the engaging portion 8 is positioned at the lower end 7 b of the guide groove 7, the rotation of the engaging portion 8 using the protrusion 9 as a support shaft is limited by the front wall portion 62 that forms the recess 6. . For this reason, the rotation of the cover 42 is limited, and the cover 42 is designed not to be opened.

  When opening the cover 42, for example, when a person pushes the cover 42 rearward with fingers, the protrusion 9 slides rearward and upward along the guide groove 7 as illustrated in FIG. As a result, the entire cover 42 moves rearward and obliquely upward. Since a circular concave step S having a deeper groove depth is formed at the upper end 7a of the guide groove 7, the protrusion 9 of the engaging portion 8 is fitted into the circular concave step S and stably held. . At this time, a gap G is generated between the upper surface portion of the casing body 41 and the back surface of the cover 42, and even when the cover 42 is in a closed state, the vicinity of the upper surface front end F of the casing body 41 is exposed.

In this case, the engaging portion 8 rotates approximately 90 ° from the horizontal state with the protrusion 9 as a support shaft. Simultaneously with the rotation of the engaging portion 8, the cover 42 rotates rearward and the upper portion of the casing body 41 is opened. In addition, since the engaging part 8 slides rearward and obliquely upward along the guide groove 7, the rotation of the engaging part 8 is not limited by the front wall part 62 that forms the recess 6.

  When the cover 42 is rotated rearward and the upper portion of the casing body 41 is opened, the back surface of the rear end portion 42b of the rotated cover 42 is in contact with and supported near the upper end portion 41b of the back surface of the casing body 41. Thus, it is preferable that the cover 42 can stand upright. Since the back surface of the rear end portion 42b of the rotated cover 42 is abutted and supported, the standing state of the cover 42 can be further stabilized. Therefore, for example, the position and length of the guide groove 7, the engagement portion 8, and the like so that the back surface of the rear end portion 42 b of the cover 42 rotated near the upper end portion 41 b of the back surface of the casing body 41 is supported. It is preferable to design the shape of the side piece 81 and the like. Further, it is preferable that the vicinity of the upper end on the back surface P side of the casing main body 41 is inclined forward, and the vertically rising cover 42 is positioned in front of the back surface P of the casing main body 41. Accordingly, even when the cover 42 is opened, the cover 42 does not protrude rearward, so that the cover 42 can be easily opened regardless of the installation environment of the western style toilet device 1. Here, “vertical” for an upright cover does not strictly mean 90 °, and an error of about ± 10 ° can be allowed.

  Further, when closing the opened cover 42, a procedure reverse to the procedure illustrated in FIGS. 7 to 9 can be performed.

  That is, when the cover 42 is opened, the protrusion 9 is positioned at the upper end 7a of the guide groove 7 (the state illustrated in FIG. 9), and the cover 42 is rotated forward with the protrusion 9 as a support shaft. The cover 42 can be tilted substantially horizontally (the state illustrated in FIG. 8). In this state, the upper surface front end F vicinity of the casing body 41 is exposed. Then, for example, by applying a force so that the cover 42 that is tilted substantially horizontally is pulled slightly forward, the projection 9 slides obliquely forward and downward along the guide groove 7 and moves to the lower end 7 b of the guide groove 7. . For this reason, the entire cover 42 is also moved obliquely downward in the forward direction, the upper surface portion of the casing body 41 is covered, and the cover 42 is closed (the state illustrated in FIG. 7).
