Abstract: A cover-side peripheral wall includes an inner wall, which serves as a first wall, and a bent wall. The inner wall is located between an inner wall and an outer wall of a body-side double-wall. The bent wall extends inward and downward from an inner surface of the inner wall. The bent wall has a proximal end that is located upward from an upper end of the inner wall of a body-side peripheral wall. The bent wall further includes a portion between a distal end and the proximal end that is located inward and downward from the upper end of the inner wall of the body-side peripheral wall.

Abstract: A vehicle-mounted component can be fixed to a vehicle body panel in a space efficient manner using a through hole of the vehicle body panel and the box main body and the cover member are easily attached to each other. In a vehicle-mounted component a cover member is attached to a box main body, a first side surface of a peripheral wall of the box main body is a covering lid wall portion that protrudes more in the height direction of the peripheral wall than other side surfaces, and the covering lid wall portion is fixed to a vehicle body panel via a hook recessed portion and a lock fitting portion by the hook recessed portion and the lock fitting portion provided in the covering lid wall portion being inserted into a through hole of the vehicle body panel and being fitted into peripheral edge portions facing each other.

Abstract: An electrical junction box that prevents deformation of a casing and breakage of a printed board due to an inserting force of a connector or the like is provided. A printed board is contained in a lower casing member. A bus bar laminated element is contained in the lower casing member above the printed board. An electrical component containing section including juxtaposed connector containing portions is provided on an upper side of an upper casing member above the bus bar laminated element. The upper casing member is mounted on the lower casing member. An upper reinforcement rib extends down from a lowermost stage insulation plate in the bus bar laminated element at a location below the electrical component containing section. The upper reinforcement rib is inserted into a through-hole in the printed board to extend down toward a bottom surface of the lower casing member. A lower reinforcement rib extends up from the bottom surface of the lower casing member to oppose the upper reinforcement rib.
