It is In the present embodiment, the engagement hole 58h is a through hole penetrating through the engagement wall portion 58 in the left-right direction.

The engagement hole 58h has a circular shape when viewed from the left and right sides. The engagement hole 58h is formed such that the diameter of the engagement wall portion 58 gradually decreases from the inner surface side facing the inside in the width direction of the toilet seat device 12 toward the outer surface side.

The distal end portion 731 of the ball shaft 730 of the toilet lid rotating member 70 is engaged with the engaging hole 58h of the engaging portion 56 of the reinforcing plate 5 . In this embodiment, the ball shaft 730 and the engaging hole 58h constitute a ball plunger 740. As shown in FIG.

Although FIG. 3 shows only the right side of the toilet seat device 12, the left side of the toilet seat device 12 is provided with a support shaft (not shown). As with the right side of the toilet seat device 12 , the support shaft is fitted to the toilet lid rotating member 70 , and the toilet lid rotating member 70 is engaged with the engaging portion 56 of the toilet lid 4 .

By rotating the drive shaft portion 61 with the driving force of the drive motor, the toilet lid rotating member 70 fitted to the drive shaft portion 61 and the toilet lid 4 engaged with the toilet lid rotating member 70 are rotated. It can be rotated (opened and closed) with respect to the cover 20 .

As shown in FIG. 3 , when the toilet lid 4 is in the closed position, the opening 724 of the second rotating body 720 faces forward, and the annular portion 27 of the cover 20 is arranged in front of the opening 724 . As a result, the engaging portion 56 of the toilet lid 4 interferes with the annular portion 27 of the cover 20 and is not removed from the slit 721 and the insertion portion 723 of the toilet lid rotating member 70 .

FIG. 6 is a view showing the toilet lid rotating member 70 as seen from the right side. 6 shows a case where the toilet lid 4 is in the open position, and illustration of the toilet lid 4 and the reinforcing plate 5 is omitted.
As shown in FIG. 6, when the toilet lid 4 is in the open position, the opening 724 of the second rotating body 720 faces upward, and the notch 28 of the annular portion 27 of the cover 20 is above the opening 724. is arranged (annular portion 27 is not arranged). As a result, the engaging portion 56 of the toilet lid 4 (see FIG. 1; the same applies hereinafter) is removed from the slit 721 and the insertion portion 723 (see FIG. 4; the same applies hereinafter) of the toilet lid rotating member 70, and the opening is 724 and the notch 28 of the cover 20 can be passed through to remove the toilet lid 4 from the main body 1 . Further, when the toilet lid rotating member 70 is at the position, the engaging portion 56 of the toilet lid 4 is passed through the notch portion 28 of the cover 20 and the opening portion 724 of the toilet lid rotating member 70, and the toilet lid rotating member 70 is moved. The toilet lid 4 can be attached to the body portion 1 by inserting it into the slit 721 and the insertion portion 723 of the lid rotating member 70 .

In the toilet device 100 configured as described above, the toilet lid rotating member 70 for rotating the toilet lid 4 is engaged with the engaging portion 56 of the toilet lid 4 . Since the engaging portion 56 is made of metal and has strength, the size of the engaging portion 56 can be made smaller than that of the engaging portion 56 made of resin or the like. Therefore, since the amount of projection of the engaging portion 56 projecting from the toilet lid 4 toward the functional portion 10 can be reduced, a large area for the functional portion 10 can be secured.

In addition, since the engaging portion 56 is made of metal and has strength, the side wall portion 44 of the toilet lid 4 can be made thinner, and the design of the toilet lid 4 in the closed position viewed from above can be improved.

Further, the second rotating body 720 that can rotate about the axis with the lateral direction as the axis direction is engaged with the engaging portion 56 of the toilet lid 4 . Even if a load that rotates the second rotating body 720 and the engaging portion 56 while engaging with each other acts, the second rotating body 720 and the engaging portion 56 are formed of a metal material. 720 and engaging portion 56 are not damaged.

Moreover, since the first rotating body 710 and the second rotating body 720 made of metal are strong and the sizes of the first rotating body 710 and the second rotating body 720 can be reduced, various devices can be installed in the functional unit 10 . There are few restrictions when arranging members such as

The toilet lid rotating member 70 is formed with an opening 724 that opens in a direction orthogonal to the left-right direction (axial direction), and the engaging portion 56 of the toilet lid 4 can pass through the opening 724. . Therefore, the toilet lid 4 is moved in a direction orthogonal to the axial direction, that is, from above to below in this embodiment, and the engaging portion 56 of the toilet lid 4 is passed through the opening 724 of the toilet lid rotating member 70, thereby A lid 4 can be attached to the body portion 1 . Also, the toilet lid 4 can be lifted upward to release the engagement between the engagement hole 58h formed in the engagement portion 56 and the ball shaft 730, and the toilet lid 4 can be removed.

Further, the toilet lid 4 can be reliably engaged with the toilet lid rotating member 70 by the ball plunger 740 that engages the ball shaft 730 with the engagement hole 58 h formed in the engaging portion 56 .

When the toilet lid 4 is attached to the main body 1 , the ball shaft 730 of the toilet lid rotating member 70 is engaged with the engagement hole 58 h of the reinforcing plate 5 of the toilet lid 4 . The ball shaft 730 is biased by the biasing portion, and when the ball shaft 730 engages with the engagement hole 58h, it makes a sound and the operator feels a response. It is easy to understand that it was attached to 1.

A metal reinforcing plate 5 is provided on the lower surface of the lid body 41 in the closed position and the inner surface of the side wall portion 44 . Therefore, deformation of the toilet lid 4 due to external force can be suppressed.

When the toilet lid 4 is lifted in the open posture, the engagement between the tip 731 of the ball shaft 730 of the toilet lid rotating member 70 and the engaging hole 58h of the reinforcing plate 5 of the toilet lid 4 is released. , and the toilet lid 4 is removed from the body portion 1 . Therefore, when the toilet lid 4 is not removed, a load is applied to the toilet lid rotating member 70 engaged with the toilet lid 4, but in the toilet device 100, since the toilet lid 4 is removed, such a load does not occur. do not have.

A toilet lid rotating member 70 for rotating the toilet lid 4 is arranged in the functional portion 10 . Therefore, in the present embodiment, the thickness ( A compact design can be achieved by reducing the lateral width t1 (see FIG. 1).

It should be noted that the toilet device 100 according to the present invention is not limited to the above-described embodiment, and appropriate modifications, replacements, and the like are possible without departing from the gist of the present invention.

For example, in the embodiment shown above, both the engaging portion 56 and the second rotating body 720 are made of a metal material, but the present invention is not limited to this. At least the engaging portion provided on the toilet lid should be made of a metal material.

In addition, in the embodiment shown above, the engaging portion 56 of the toilet lid 4 can be taken out and inserted from the opening 724 of the second rotating body 720, and the toilet lid 4 can be removed from the body portion 1. , the present invention is not limited to this. Although it is preferable that the toilet lid 4 is removed, it may be configured such that it cannot be removed.

Further, in the embodiment shown above, the engaging portion 56 is engaged with the ball shaft 730 by the ball plunger mechanism, but the present invention is not limited to this. The configuration may be such that the engaging portion of the toilet lid engages with the recess.

Further, in the embodiment shown above, the toilet lid 4 is provided with the reinforcing plate 5, but the present invention is not limited to this. A configuration in which the metal engaging portion is directly provided on the side wall portion 44 of the toilet lid 4 without providing the reinforcing plate 5 may be employed.
