Abstract: A steering wheel core metal unit comprising a boss section, a boss/spoke connecting section, spoke sections and a ring section integrally die-cast, with the boss section serving as an insert. Before trimming and after being released from a die caster, the boss/spoke connecting section of the core metal unit is provided with a gate section and the ring section comprises a pair of inside and outside ribs. Overflow sections are provided along the outer periphery of the ring section at substantially the intermediate positions among the spoke sections, respectively. The sectional area of the outside rib is made larger than that of the inside rib so that a final molten metal merging portion comes to lie at the outer periphery of the ring section. Accordingly, even when the molten metal moves in the cavity of the die caster as it entrains air, the air can escape from the overflow sections and no blowhole is formed in the core metal as a die cast product.

Abstract: There is provided a lubricating structure of a planetary gear mechanism which can simplify the outer shape of an introducing section formed by an oil catch plate, for introducing lubricating oil, and ensure a high degree of design freedom. In a double pinion type planetary gear mechanism, the distance from the axis of a carrier to the outermost edge of an opening in the direction of the carrier's diameter in an lubricating oil introducing hole formed in an outer diameter side pinion shaft and the distance from the axis of the carrier to the outermost edge of an opening in the direction of the carrier's diameter in an lubricating oil introducing hole formed in an inner diameter side pinion shaft are equal to each other. Therefore, lubricating oil can be supplied to the inner diameter side pinion shaft through the introducing section irrespective of the amount of lubricating oil that can be supplied to the outer diameter side pinion shaft. Also, the shape of a centrifugal cancel piston as the oil catch plate forming the introducing section can be simplified to increase the degree of design freedom.

Abstract: An air bag equipped steering wheel that absorbs impact energy of a forward impact, even if applied to the rear side of a ring portion thereof. The steering wheel comprises core bars for connecting its ring portion, boss portion and spoke portions to each other. The spoke portions are composed of two front spoke portions arranged at the right and left of the front side, and a rear spoke portion arranged at the rear side. The air bag unit is securely mounted on the core bars of the front spoke portions and the rear spoke portion. Twistable torsional portions are formed at the core bars of the front spoke portions at positions closer to the core bar of the ring portion than the mounting portion for the air bag unit. A first deformable bent portion is formed at the core bar of the rear spoke portion at the side closer to the boss core bar than the mounting portion for the air bag unit. A second bendable bent portion is formed at the core bar of the ring portion than the mounting portion of the air bag unit and the column cover. The first bent portion is given a lower bending rigidity than the second bent portion.
