Abstract: A conductive bus bar includes a first plate-shaped portion extending in a first direction and a second plate-shaped portion continued from the first portion and extending in a second direction perpendicular to the first direction. The second plate-shaped portion has a first main face which faces the first plate-shaped portion, a second main face opposite to the first main face, and side faces connecting the first main face and the second main face. A press-contact portion is formed in the second plate-shaped portion, to which an electric wire is press-fitted. An insulative mount includes a mount face, on which the first plate-shaped portion is disposed, and a wall member extending in the second direction to support the second main face of the second plate-shaped portion. A pair of rib members are extended from the wall member to support the side faces of the second plate-shaped portion.

Abstract: The disclosed method produces a spline-grooved cylindrical member, e.g. torque converter front cover, including a cylindrical portion having a target wall thickness t2, from a plate blank having a plate thickness t1. An outer peripheral portion of a disc-shaped blank is plastically deformed by pressing it against a mandrel with the concave peripheral edge of a thickness-increasing roller, so that a thick wall portion, of a thickness greater than the plate thickness t1 of the blank, is formed in the cylindrical portion. The thick wall portion is then pressed against the mandrel by forming rollers to form spline grooves therein. Thus, the other portions of the product have a wall thickness which is not unnecessarily increased. In this manner, the wall thickness t2 of the cylindrical portion is not entirely dictated by the wall thickness t1 of the blank material.

Abstract: An assembling structure of an electronic unit to an electrical connecting box is provided. This assembling structure is provided with a miss-connection preventing portion on at least one of an electrical connecting box and an electronic unit combined to each other. The miss-connecting preventing portion is put in an interfering state with the mating side member to prevent the combination thereof when the two are combined improperly. The miss-connection prevention portion is provided at a peripheral wall portion of the electronic unit so that it interferes with a peripheral wall portion of the electrical connecting box when combination of the electrical connecting box and the electronic unit is improper.

Abstract: The present invention is to provide an assembling structure of an electronic unit to an electrical connecting box which is not subjected to any spatial limitation when electrical parts are mounted on an electronic unit and which is provided with a miss-connection preventing function.

Abstract: A tubular portion is formed on a ceiling surface of a lid which covers a body. The tubular portion is received in an upper recess portion in a manner to cover a plate-like terminal.

Abstract: An electrical junction box having a screw-tightening type fusible link. The electrical junction box includes a screw-tightening type fusible link having at least one pair of terminals, a first electrical junction box having a housing for mounting the screw-tightening type fusible link and a recess portion which is adjacent to the housing for mounting the screw-tightening type fusible link, a second electrical junction box which can be mounted in the recess portion of the first electrical junction box, at least one wire harness in which one end of the wire harness is securely tightened to the terminal of screw-tightening type fusible link by a bolt, and an operation space for tightening where the bolt, the operation space is defined so as to be identical with the recess portion of the first electrical junction box before the second electrical junction box is mounted.

Abstract: For a first vehicle kind requiring a first internal circuit to have a first connection circuit for connection of a first set of electrical inserts or a second vehicle kind requiring a second internal circuit to have a second connection circuit for connection of a second set of electrical inserts, the first and second connection circuits being different from each other, a case member is molded with external portions for installation of a corresponding one of the first and second sets of electrical inserts and an internal space including a channel network, and has installed in the internal space the first internal circuit with a first connection circuit composed of a combination of first bus bars set in the channel network, or the second internal circuit with the second connection circuit composed of a combination of second bus bars set in the channel network.

Abstract: An electrical junction box includes a cover body having a plurality of cavities with which a plurality of electrical components are engaged; and rear covers which are separately provided for each of sub wire harnesses W1 and W2, and are fixedly combined with the cover body. With the electrical junction box of the invention, connection of power lines is achieved with a general connector, and the connector is connected to a housing which is provided on any one of the rear covers.

Abstract: In a different nuts assembling construction in which according to the kind of nuts 71, 73, there are provided plural pairs of nut fitting grooves 61, 63 into which both sides of seats 75, 77 of nuts 71, 73 are fitted, the thicknesses D1, D2 of seats 75, 77 of nuts 71, 73 are formed in a manner to be different for each kind of the nuts 71, 73; and the groove thicknesses of the nut fitting grooves 61, 63 are formed by being matched to the thicknesses D1, D2 of corresponding seats 75, 77, so that where an attempt is made to fit the 71, 73 into wrong nut fitting grooves 61, 63, the thicknesses D1, D2 of the seats 75, 77 are not matched to the groove thicknesses of the nut fitting grooves 61, 63, whereby a worker can easily detect that the kind of the nuts 71, 73 is wrong.

Abstract: An airbag with an inflation gas diffuser comprising an inflator side cloth and an occupant side cloth both of a substantially equal size and a generally circular shape seamed together at outer peripheral portions thereof to form an outer configuration of the airbag. The inflator side cloth has a central opening through which to communicate with an inflator, and an internal cloth of a smaller size enclosed within the airbag to cover the opening. The internal cloth is partially seamed at its outer perimetric portion, to the inflator side cloth so as to form circumferentially alternately seamed portions and non-seamed open portions acting as a control passage for the inflation gas. The internal cloth may be circular, semicircular, dumbbell, polygonal, etc. The seamed portions each may consist of a main straight seam and two curved end seams.
