BACKGROUND OF THE INVENTION Many stadiums are built as multipurpose grounds. For this reason, for example, the post used to set the goal of a soccer must be removed when playing another game that does not require the post. Since such a post hole is provided in the field, it must be completely closed after being removed. Otherwise, it may affect the competition. In addition, the installation and removal of such posts must be done promptly in order to manage the competition.

In the conventional device of this type, two types of lid members, one for competition and one for non-competition, are required to be flush with the field surface. Therefore, if another lid member is inserted and installed in one post hole, unevenness may occur. This is because the foundation for installing the holes for posts is made of concrete, and the concrete foundation surface has individuality. If unevenness occurs, it may cause irregular bands and affect the competition.

In addition, replacement of the lid member requires transporting the respective lid members from the outside of the field to the inside of the field, and in practice, the lid must be reciprocated many times over a wide field, so that it takes time to install the post. There was a flaw.
