However, in a toilet seat device that attaches to and detaches from the main body by elastically deforming the toilet lid, it is necessary to make the toilet lid strong enough to withstand the elastic deformation when attaching and detaching the toilet lid separately from its function. There's a problem.
In addition, in a toilet seat device that switches between a state in which the toilet lid is engaged with the main body by a lever and a state in which the engagement is released, the operation of the lever and the operation of attaching and detaching the toilet lid must be performed at the same time. is complicated.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a toilet seat device in which a toilet lid can be easily attached to and detached from a body portion installed in the upper rear portion of a toilet bowl.

In order to achieve the above object, a toilet seat device according to the present invention is a toilet seat having a main body installed in the upper rear part of a toilet bowl, a toilet seat attached to the main body, and a toilet lid for opening and closing the upper part of the toilet seat. In the apparatus, the toilet lid includes a toilet lid main body that closes the upper portion of the toilet seat, a shaft engaging portion that is attached to the toilet lid main body and is attachable to and detachable from a shaft portion provided on the main body, and the toilet lid. and a movable portion provided movably with respect to the main body, wherein the shaft engaging portion has an engaged state in which it is engaged with the shaft portion and a non-engaged state in which the engagement with the shaft portion is released. When the movable portion provided on the toilet lid main body is pushed backward against the toilet lid main body in the engaged state, the movable portion is moved to the toilet lid main body. and is switched to the non-engaged state.

In the present invention, the shaft engaging portion attached to the toilet lid body in the engaged state is switched to the disengaged state when the toilet lid body is pushed away from the toilet seat. By pressing the lid body away from the toilet seat, the shaft engaging portion in the engaged state can be easily switched to the disengaged state.
Since the toilet lid with the shaft engaging portion in the disengaged state can be easily attached to and detached from the shaft portion, the toilet lid can be easily attached to and detached from the main body portion.

Further, in the toilet seat device according to the present invention, the shaft engagement portion may have a biasing portion that biases the posture from the non-engagement state to the engagement state posture.
With such a configuration, the shaft engaging portion in the non-engaged state can be easily switched to the engaged state by not pressing the toilet lid main body in the direction away from the toilet seat.

A toilet seat device according to the present invention is a toilet seat device comprising: a main body installed on the rear upper part of a toilet bowl; a toilet seat attached to the main body; and a toilet lid for opening and closing the upper part of the toilet seat, wherein the toilet lid is a toilet lid main body that closes the upper portion of the toilet seat; and a shaft engaging portion attached to the toilet lid main body and detachable from a shaft portion provided on the main body portion, wherein the shaft engaging portion is and a non-engaged state in which the engagement with the shaft is released, wherein the toilet lid main body is separated from the toilet seat in the engaged state. The shaft engaging portion is opened downward to allow the shaft to be taken in and out from the bottom and accommodated in the shaft; When it moves to one side in the movable direction, it closes the bottom side of the recess to enter the engaged state, and when it moves to the other side in the movable direction, the bottom side of the recess opens to open the non-engaged state. The movable portion has a contact portion with which the shaft portion located below the concave portion can contact from below, and the contact portion has a lower side may be formed on an inclined surface that gradually extends from the other side toward the one side in the movable direction.
With such a configuration, when the toilet lid is attached to the main body, when the toilet lid is moved downward by its own weight while the contact portion is brought into contact with the shaft from above, the contact portion (movable portion) ) moves downward along the shaft portion, and moves to the other side in the movable direction due to the reaction force from the shaft portion to be in a disengaged state. Since the lower side of the recess opens when the movable portion is disengaged, the shaft can be accommodated in the recess when the toilet lid is moved further downward by its own weight.
In this way, the toilet lid can be easily attached to the main body using the weight of the toilet lid.

ADVANTAGE OF THE INVENTION According to this invention, a toilet lid can be easily attached or detached with respect to the main-body part installed in the rear upper part of a toilet bowl.
