PROBLEM TO BE SOLVED: To improve the workability of a work object disposed in a recessed part and prevent a cover member covering the recessed part from being unexpectedly moved and opening the recessed part.SOLUTION: In a housing structure 1, a recessed part 3 opens on two outer surfaces 2a, 2b arranged perpendicular to each other and a cover member 5 includes: a first cover part 20 covering a first opening 3A of the recessed part, which opens on a first outer surface 2a, and a second cover part 30 covering a second opening 3B of the recessed part, which opens on a second outer surface 2b. The first cover part linearly moves in an AB direction to open and close the first opening, and the second cover part is rotatably connected with the first cover part disposed in a first closed position 20A to open and close the second opening. The second cover part restricts the first cover part from linearly moving from the first closed position in an A direction when being disposed in a second closed position 30A. The second cover part allows the first cover part to linearly move in the A direction while being disposed in a second opening position. |
