  • Patent number: 8162360
    Abstract: A handle knob to conduct an opening/closing operation of a front door is provided on an outer-face side of an outer panel, and a handle base to pivotally support the handle knob is provided on an inner-face side of the outer panel. A beltline reinforcement to reinforce an beltline portion of the outer panel is provided on the inner-face side of the outer panel. The handle base is connected to the beltline reinforcement via an connecting portion. Thereby, the support rigidity of the handle base can be increased, thereby properly preventing the handle base from moving by an improper access.

  • Patent number: 8128137
    Abstract: To provide a supporting structure of a rotating section which offers not only facilitated mounting but also resistance to dropout. There are provided a handle base 1 for rotatably supporting one end side of a handle grip 2, and a lever 3 which has a shaft section 23 rotatably supported by a bearing section 11 of the handle base 1 and which is rotated upon pulling of the handle grip 2. The lever 3 includes a first shaft tip section 27 projecting from the shaft section 23 to a shaft tip side and having a part cut away so as to form a circular face, and a second shaft tip section 28 projecting from the first shaft tip section 27 to a shaft tip side and having a width smaller than that of the first shaft tip section 27.

  • Patent number: 8118344
    Abstract: There is provided a slide door structure of a vehicle which has a slide door to slide in a vehicle longitudinal direction at a side of a vehicle body, comprising a center rail which extends in the vehicle longitudinal direction at the side of the vehicle body so as to guide a roller provided at the slide door, and an expansion preventing bracket which is provided at a front end portion of the center rail so as to connect a pair of guide-face portions which face to each other for preventing an expansion of a center-rail end. Accordingly, the expansion of guide-rail end can be prevented in case the outward load acts on the slide door when the slide door is in the closed state.
