Abstract: In a design method of torsion bars used for a trunk lid, free shapes of the torsion bars unhitched from the trunk lid are designed. A center line model of the initial free shape is geometrically and statically created on the basis of a design specification. The center line model of an open shape is created from the free shape model and is deformed into a center line model of a closed modified shape. The center line models of the analyzed closed shape and the target closed shape is compared with each other to obtain a difference torque and a difference vector occurring between corresponding nodes on the center lines. The center line model is so changed as to decrease the difference torque and the difference vector.

Abstract: A suspension includes a load beam and a flexure. The flexure has a metal base and a conductive circuit portion. The conductive circuit portion has an insulating layer formed on the metal base, and a conductor formed on the insulating layer. The conductive circuit portion includes a first region which constitutes a part of the conductive circuit portion in the longitudinal direction, and a second region which constitutes another part of the same in the longitudinal direction. The conductor includes a thin conductor portion having a first thickness arranged in the first region, and a thick conductor portion having a second thickness arranged in the second region. The second thickness is greater than the first thickness.

Abstract: A vertical motion impeller-type shot peening device performs a second shot peening to a coil spring including first shot peening indentations. The vertical motion impeller-type shot peening device includes a workpiece holding mechanism including a lower end turn support and an upper end turn support, a stress applying mechanism which compresses the coil spring, a rotation mechanism, and a projection mechanism which includes a pair of vertically movable impeller units. A first rough surface including first shot peening indentations is formed on a part of end turn portions of the coil spring. A second rough surface including second shot peening indentations is formed on the entire surface of wire except for the first rough surface.

Abstract: According to one embodiment, a shift actuator includes a main body section and a shaft section. The main body section has an electric motor which has a vertically extending rotating shaft, and a gear mechanism which rotates the shaft section in accordance with the rotating shaft. The shaft section has a threaded shaft extending parallel to the rotating shaft and made to rotate by the gear mechanism in accordance with the rotating shaft and a movable nut which is screwed onto the threaded shaft and moves upward or downward with rotation of the threaded shaft. The movable nut is connected with a shift member which changes the gears of a propeller shaft.
