2. Description of the Related Art Conventionally, a toilet seat and a toilet lid are rotatably supported by a toilet bowl or a warm water washing device. However, since the toilet seat and the toilet lid do not buffer the rotation, when the hands are released during the fall, The toilet seat or lid may drop violently and make loud noises or be damaged.

For this reason, the applicant of the present application filed
Japanese Patent Publication No. 295 has already proposed a structure in which the rotation cushioning device damps the rotation of the toilet seat and the toilet lid. In this conventional example, the rotary cushioning device for the toilet seat and the rotary cushioning device for the toilet lid are respectively installed inside the hot water washing device, and the hinge pin is inserted into the toilet seat and the toilet lid to further form the main body case of the hot water washing device. It is inserted through the opened hole and its tip is detachably engaged with the rotary shaft of the rotary shock absorber installed inside the main body case, and the toilet seat is used as the rotary shaft of the rotary shock absorber for the toilet seat through the hinge pin. When the toilet seat is engaged, the rotation of the toilet seat is buffered by the rotation cushioning device for the toilet seat, and the toilet lid is engaged with the rotating shaft of the rotation cushioning device for the toilet lid via the hinge pin to facilitate the rotation of the toilet lid. It was designed to be buffered by a rotary buffer device for the lid. Then, remove the toilet seat or toilet lid to clean the toilet seat or toilet lid, or clean the rear portion of the toilet seat or the hot water cleaning device.In this case, pull out the hinge pin to remove the toilet seat or toilet lid. I am supposed to do it.

Therefore, there is a possibility that water may enter the main body case through this hole during cleaning, which adversely affects electric components in the main body case for hot water cleaning.

Further, in the above-mentioned conventional example, since it is necessary to pull out the hinge pin laterally at the rear portion of the toilet seat and the toilet lid, it is difficult to pull out the hinge pin, and it is extremely difficult for the user to do this. There is a problem, and when attaching the toilet seat and toilet lid again with hinge pins,
Since it is necessary to insert and attach the hinge pin to the toilet lid at the same time, it is difficult to align the holes, and in this case, it is necessary to position the hinge pin with the rotary shaft of the rotary shock absorber inside the main body case. There is also a problem that it is necessary to match them, and it is difficult to reattach the hinge pin after cleaning is completed.

Further, since the hinge pin is a small part, it may be lost during cleaning after removal. The present invention has been made in view of the above-mentioned problems of the conventional example, and even if the toilet seat or the toilet lid is removed, no holes are opened in the main body case, and the inside of the main body case is cleaned during cleaning. Water does not enter, and the toilet seat,
The toilet lid can be easily attached and removed, and the toilet seat and toilet lid will not accidentally come off during normal use.

The portion faces downward, and in this state, by pulling up the toilet seat 4 upward, the opening of the first bearing portion 13 can be pulled out upward from the toilet seat pivot support projection 6. In this case, the leaf spring is elastically deformed by applying an upward pulling force at the same time, and the first elastic locking portion 17 is elastically deformed to get over the chevron portion 23 and have a substantially U-shaped cross section. The attachment / detachment connection part 11 is pulled out upward from the toilet seat connection part 5.

In this way, the toilet seat 4 and the toilet lid 14 are removed for cleaning. In this case, the rotary shaft 3 for the toilet seat and the toilet lid are inserted from the wall portions 21 on both sides of the recess 20 of the main body case 1. Since it is not necessary to remove the rotary shaft 8, the holes into which the rotary shaft 3 for the toilet seat and the rotary shaft 8 for the toilet lid are inserted do not open, and therefore, the rotary shaft 3 for the toilet seat and the toilet lid during cleaning. Water does not enter the inside of the main body case 1 through the hole after the rotary shaft 8 is pulled out, and there is no adverse effect of the intruded water on the electric parts and the like that are internally installed in the main body case 1. It is a thing.

By the way, as is clear from FIGS. 1 to 4, the toilet seat 4 and the toilet lid 14 are buffered when they are tilted by the toilet seat rotating cushioning device 2 and the toilet lid rotating cushioning device 7, respectively, as described above. In this case, since the rotatably supporting portions of the toilet seat 4 and the toilet lid 14 are located on the same axis, the structure of the rotatably supporting portion becomes compact. When the toilet seat 4 and the toilet lid 14 are removed for cleaning, in the present invention, the toilet seat rotary shaft 3, the wall 21 on both sides of the recess 20 of the main body case 1,
Only the rotary shaft 8 for the toilet lid and the projection 6 for the toilet seat shaft support are located,
Moreover, since the toilet lid rotary shaft 8 and the toilet seat shaft support projection 6 are located on the same axis, the shaft support member is less likely to get in the way during cleaning and can be easily cleaned. is there.
