Abstract: A casing for housing an occupant protection device unit is composed of a metallic base with its plate surfaces facing upward and downward, respectively, and a main body that is put on and mounted on the surface of the base. A bracket formed integrally with the base is composed of a plate-like leg extending laterally from the edge in the base and a fastening member that is integrally formed at an end of the leg and is bolted to the vehicle body. The leg is composed of a through-hole vertically passing therethrough and the two weak portions. The two weak portions are composed of two branching portions separated by the through-hole in the leg. If an excessive collision load is exerted on the bracket from the vehicle body, the two weak portions are torn off, thereby allowing the occupant protection control unit to be protected.

Abstract: A casing for housing an occupant protection device control unit is mounted to a vehicle body. The casing is composed of a metallic base mounted on the vehicle body with its plate surfaces facing upward and downward, respectively, and a main body that is put on and mounted on the base. The base has a lock portion that is deformable according to a deformation of the vehicle body caused by a collision load from a vehicle front. The lock portion, when deformed, causes a front portion of the base to be locked with at least a part of a front wall of the main body.

Abstract: An earth device is an earth device for earthing an object to be earthed. The earth device includes an earth-side wire, a detection-side wire which is normally out of conduction with the earth-side wire, an attachment member provided on one end portion of each of the earth-side wire and the detection-side wire and attached to the object to be earthed to provide conduction between the earth-side wire and the detection-side wire, an earth member for earthing provided on the other end portion of each of the earth-side wire and the detection-side wire, and a detection means connected to the detection-side wire to detect conduction in the detection-side wire.

Abstract: A rotary piston engine includes a generally triangular rotor, a pair of side housings, a rotor housing which is assembled with the rotor and the pair of side housings to define three working chambers, an intake port formed in at least one of the side housings, and an exhaust port formed in at least one of the side housings. The length of one side of the triangular face of the rotor is at least 2.4 times the breadth of the rotor.
