  • Patent number: 7621196
    Abstract: A shift lever device has resin pieces, and a resin outer tube which is formed at an outer side of a shift lever main body. The resin pieces and the resin outer tube can be molded separately. Therefore, the resin pieces independently can be molded with high precision. Even in a structure in which interposed portions of the resin pieces are interposed between a detent pin and inner walls of long holes of the shift lever main body, the interposed portions do not project-out unnecessarily at an inner side of the shift lever main body. Resin can be interposed between the detent pin and the long holes of the shift lever main body, without carrying out precise inspection or repair work.
    Type: Grant

    Date of Patent: November 24, 2009

  • Patent number: 6335499
    Abstract: Wobble caused between an operation knob and a casing for housing the operation knob is suppressed as small as possible due to the heat contraction at the time of a molding process. As a result, the operation knob can be downsized and so an assembly of the operation knob and the casing can be miniaturized as compared with the conventional ones. The operation knob and the casing for guiding the movement of the operation knob are formed by composite resins by using a dichroic molding method, and then the operation knob and the casing are separated after being molded to obtain an assembly. Due to the heat contraction at the time of the molding process, a necessary guide clearance is formed between the operation knob and the casing after the assembling of the operation knob and the casing. The operation knob is allowed to move due to the guide clearance.
