And a box body in which a device is disposed inside and a box shape formed by standing upright, and a lid body that is openably and closably attached so as to close the opening of the box body. In a device arranging box in which a through hole is provided in at least one of the opposing plates, the substrate and a side plate erected from an edge of the substrate, the side plate being a through hole of the lateral opposing plate. The box body is provided with a crowned member which is crowned in a facing state.

According to a second aspect of the present invention, in the first aspect, a through hole is provided in the lower facing plate.

According to a third aspect of the present invention, in the second aspect, the lid is provided with an engaging portion, and the engaging portion and the through hole of the lower facing plate are engaged with each other. A pushing member for pushing the lid is detachably provided.

According to a fourth aspect, in the third aspect, the lower facing plate has a plurality of through holes.

[0010]

According to the first aspect of the present invention, since the crown member is crowned on the box body with the side plate facing the through hole provided in at least one of the side facing plates, the box body is The inside is ventilated through the through holes in a state where rainwater or the like does not enter.

According to the second aspect of the present invention, since the box main body is provided with the through holes also in the lower facing plates thereof, the inside is entirely ventilated through the through holes of the lower and side facing plates. To be done.

According to the third aspect of the present invention, the lid body is held in the open state when the projecting member engages with the engaging portion and the through hole of the lower facing plate and is stretched.

According to the fourth aspect of the present invention, the lid body is maintained in an open state at various angles because the state in which the lid body is stretched changes when the through hole in which the protrusion member is engaged is changed.
