Abstract: A bulkhead includes three flange portions. A first flange portion of the bulkhead is sandwiched between an upper flange portion of a rocker inner panel and an upper flange portion of a rocker outer panel, so as to be fixed to the rocker inner panel and the rocker outer panel. A third flange portion of the bulkhead extends from the first flange portion to bring at least a part of the third flange portion in contact with an inner surface of the rocker inner panel or an inner surface of the rocker outer panel, and is fixed to the contacted inner surface.

Abstract: A vehicular wheel house portion structure that can improve working efficiency when applying a sealer is obtained. In unhemmed portions, an end portion of a wheel house outer panel is cut off in alignment with an application center position of a sealer in a hemmed portion. Because of this, a sealer application center position in the hemmed portion and sealer application center positions in the unhemmed portions become substantially the same.

Abstract: An object of the present invention is to provide an electrical junction box having a new structure in which a lever of a lever type connector engages a connector hood and a deflection of a wall portion can be prevented without increasing an amount of a resin. Latch projections protrude from a wall portion of a connector hood toward the inside of the connector hood. The latch projections engage guide grooves in a lever of a connector. A plurality of lightening holes are formed in the wall portion. The latch projections are supported on a solid part of the wall portion that is not provided with the lightening holes.

Abstract: A knee protection apparatus includes an airbag and an airbag support that is attached to the airbag. Upon deployment of the airbag, the airbag support together expands so as to cover the instrument panel and thus help the airbag smoothly expand.

Abstract: An electrical junction box reduces the number of components to be contained in an electrical junction box and simplifies a structure of the box. The electrical junction box has a casing assembly including an upper casing and a lower casing. A laminated unit including bus bars and insulation plates is contained in the upper casing, while a first printed circuit board, a second printed circuit board and a spacer made of an insulation resin material are contained in the lower casing. The first printed circuit board is disposed on one side of the spacer, while the second printed circuit board is disposed on the other side of the spacer. Shorter size fixing bars and longer size fixing bars project from an inner surface on a top wall of the upper casing. The shorter size fixing bars penetrate the laminated unit, first printed circuit board and spacer.

The bracket section includes a top wall provided with a clip-engaging hole and opposite side walls extending downward from the top wall and that have clamping-piece portions that are opposed to each other at a distal end of the opposite side walls. The bracket is fitted on and secured to an exterior of the bracket section. The bracket includes a top plate portion provided with a clip-engaging hole and an outer plate portion extending downward from the top plate portion and that has an engaging-piece portion.

Abstract: A junction box has a casing assembly including an upper casing and a lower casing, a laminated unit including bus bars and insulation plates, and first and second printed circuit boards contained in the casing assembly. The first printed circuit board is used as a higher current circuit having thick-film conductors. The second printed circuit board is used as a middle or lower current circuit having thin-film conductors with thicknesses smaller than those of the thick-film conductors on the first printed circuit board. Board relays are mounted on a part of different peripheral portions on both sides of the first printed circuit board or a part of peripheral portion of either side of the first printed circuit board.
