  • Patent number: 10358160
    Abstract: Provided is a steering wheel which includes a spacer (19) having a first base portion (32) and a second base portion (33) which are respectively disposed on a front side and a rear side with a rim metal core portion (28) interposed therebetween and are engaged with each other to cover the rim metal core portion (28), in which the first base portion (32) and the second base portion (33) are each divided into a plurality of portions at positions different from each other in a circumferential direction of the rim metal core portion (28).

  • Patent number: 10266143
    Abstract: The present invention provides a steering wheel. Among respective hooks of a module, the hooks being adapted to engage with wires which are disposed in respective opening portions of a steering wheel main body, an adjustment rib which is provided so as to be protrusive to an outer circumferential face of one side hook comes into contact with an inside face of one side opening portion, and restrains a position of such one side hook in such one side opening portion. An adjustment pin which is protrusively provided at a position different from that of the adjustment rib on the outer circumferential face of such one side hook elastically comes into contact with the inside face of such one side opening portion by the adjustment rib coming into contact with the inside face of such one side opening portion.

  • Patent number: 10196028
    Abstract: A steering wheel includes a steering wheel body including at least two insertion openings, and an airbag module including at least two hooks inserted into the insertion openings. The hooks are held by wires so that the airbag module is supported by the steering wheel body. Either the at least two hooks or the at least two insertion holes are provided with adjustment ribs which come into contact with the other ones of the at least two hooks and the at least two openings, thereby regulating the positions of the other ones, so as to receive the weight of the airbag module applied to the steering wheel body. Accordingly, a decrease in positioning performance of the airbag module is prevented, so as to regulate the position of the airbag module in the steering wheel body with high accuracy.

  • Publication number: 20180273078
    Abstract: A spacer is interposed between a rim core metal and an electronic part, so that the electronic part can be easily disposed. An opening is formed in the spacer such that the opening is positioned to face an overflow portion that is formed in a mold for molding of a resin layer and that is provided for a fluid synthetic resin raw material to overflow. Even when air bubbles are generated in the synthetic resin raw material between the spacer and a core metal, the synthetic resin raw material overflowing to the overflow portion can easily eject the air bubbles to the overflow portion via the opening and the air bubbles can be prevented from remaining in the resin layer.

  • Patent number: 9884641
    Abstract: A steering wheel includes a ring-shaped rim is to be gripped by a driver (the rim includes a rim core and a rim molding portion covering the rim core), a boss disposed at the center of the rim, plural spokes connecting the rim with the boss, an arm whose base end portion is integrated with the rim core and that is extended toward the inside of the rim core in a cantilever manner, and a vibration generator attached to the arm for generating vibrations that are to be transmitted to the rim through the arm.
