Coupling structure of housing members and storage case

A storage case comprising:

• a plurality of housing members in each of which at least a conductive member is housed as a housing object;
• and
• a coupling structure that couples two of the housing members to be coupled, wherein
• the coupling structure includes:
• a first coupling body that is disposed in one of the two housing members to be coupled;
• a second coupling body that is disposed in the other of the two housing members;
• and
• a holding mechanism that holds the first coupling body and the second coupling body in a state in which the first coupling body and the second coupling body are coupled to each other,
• the first coupling body is disposed as part of a housing body of the housing member in which the housing object is housed, has a bottom part that forms a part of a housing chamber for the housing object, and has a first vertical wall part and a second vertical wall part that are vertically disposed from the bottom part with a space interposed between the first vertical wall part and the second vertical wall part,
• the second coupling body is disposed so as to face the bottom part in a stacked state in the housing chamber, and formed so as to cover a space between the first vertical wall part and the second vertical wall part in the bottom part inside the housing chamber,
• the holding mechanism includes a first projection that projects from a first end of the second coupling body toward a side of the first vertical wall part, a second projection that projects from a second end of the second coupling body toward a side of the second vertical wall part, a first through-hole that is formed in the first coupling body and into which the first projection is inserted, and a second through-hole that is formed in the first coupling body and into which the second projection is inserted, the first end covering at least part of the first vertical wall part, the second end covering at least part of the second vertical wall part,
• the first through-hole is formed in a first corner that is a boundary between the bottom part and the first vertical wall part such that the first through-hole extends through each of the bottom part and the first vertical wall part,
• the second through-hole is formed in a second corner that is a boundary between the bottom part and the second vertical wall part such that the second through-hole extends through each of the bottom part and the second vertical wall part, and
• the second coupling body covers the first through-hole and the second through-hole from an inside of the housing chamber by covering the first through-hole and the second through-hole in the bottom part, covering the first through-hole in the first vertical wall part with the first end of the second coupling body, and covering the second through-hole in the second vertical wall part with the second end of the second coupling body, when the first projection and the second projection are respectively inserted into the first through-hole and the second through-hole.
