PURPOSE:To prevent the occurrence of dislocation even when a force in a direction in which a cover is separated away from a wall is exerted, in the mounting structure of a cover with which a recessed part formed in a wall surface is covered, in a unit room such as a unit bath. CONSTITUTION:An engaging member 4 in which a hole 41 is formed is fixed to a part of an inspection port 2. A pin-like member 5 is approximately horizontally fixed on the back of a cover 3. When the cover 3 is slid approximately horizontally as shown by an arrow mark (a) and the pin-like member 5 is inserted in the hole 41 and slightly dropped approximately in a vertical direction, a shaft 53 of the pin-like member 5 of the cover side 3 is engaged with the hole 41 of the engaging member 4. |
