Since the protrusion means for protruding to the front side in the depth direction is provided,
Even without using a tool such as a screwdriver like before,
By simply pushing one end of the small lid to the depth side of the through hole, the other end of the small lid protrudes to the front side in the depth direction, and if the protruding portion is pulled out, the The small lid can be removed. Furthermore, since the notch that is exposed on the surface does not have to be formed in the small lid, the boundary between the small lid and the lid main body is not conspicuous, and it is difficult to impair the aesthetics of the hole closing device.

According to the characterizing feature of the invention of claim 2, in addition to being able to achieve the effect of the invention of claim 1, the projecting means is in a state in which the small lid is fitted in the recess. Thus, since the small lid guiding space formed between the bottom portion of the recess and the back surface of the one end of the small lid is provided, it is possible to provide a complicated mechanism without providing a complicated mechanism. It is possible to achieve the effect of the invention. That is, as one end of the small lid is pushed to the depth side of the through hole, one end of the small lid is guided into the small lid guiding space,
Projecting the other end of the small lid toward the front side in the depth direction can be realized with a simple structure. As a result, while preventing the cost increase of the hole blocker,
It is possible to improve the functionality.

According to the characterizing feature of the invention of claim 3, in addition to being able to achieve the action and effect of the invention of claim 1 or 2, it is possible to put a finger on the back of the other end of the small lid. Since the operation recess is provided, one end of the small lid is pushed to the depth side of the through hole so that the other end of the small lid projects toward the front side in the depth direction. To perform the detaching operation to the front side, in the operation recess, for example,
It is possible to remove the small lid more easily by hooking a fingertip. Moreover, since the operation recess is hard to be exposed on the surface in the state where the small lid is attached to the lid body, it is easy to prevent the appearance from being impaired.
