  • Patent number: 8448537
    Abstract: A spring includes a coil portion and first and second arms. The coil portion is supported around a support portion of a base member. The first arm includes a projecting portion that slides the engagement projecting portion in association with rotation of the rotating lever and presses the rotating lever in a direction in which the rotating lever abuts a first stopper portion when the rotating lever is in a first position and in which the rotating lever abuts a second stopper portion when the rotating lever is in a second position. The second arm abuts a spring stopper portion of the base member in a state where a load is exerted in a direction in which the coil portion is wound so that an inner circumferential surface of the coil portion is pressed against an outer circumferential surface of the support portion facing the engagement projecting portion.

  • Patent number: 8403379
    Abstract: A door lock apparatus, at both sides of a region interposing a second link lever therebetween, includes a sector lever shaft and an inside lever shaft that extend in parallel with a swinging shaft of the second link lever. The door lock apparatus also includes an inside handle lever swingably arranged about the inside lever shaft, and when an inside door handle arranged inside a vehicle is open-operated while the second link lever is disposed in a cancel position, moves the second link lever upwards by swinging about the center of the inside lever shaft, and when the inside door handle is open-operated while the second link lever is disposed in a non-cancel position, swings the sector lever in a locked position to an unlocked position about the center of the sector lever shaft, by swinging about the center of the inside lever shaft.

  • Publication number: 20100207401
    Abstract: A vehicle door latch apparatus includes a meshing portion assembly and an operating portion assembly. The meshing portion assembly includes: a latch; and a pawl engaging with the latch for preventing a rotation of the latch. The operating portion assembly includes: a casing including a shaft portion and a slit; and an operation lever pivotally supported on the shaft portion and including a shaft hole. The slit is provided in a wall portion of the casing at right angles to a rotating plane of the operation lever. The operation lever enters the slit in a waiting position. A movement of the operation lever in a direction of a rotating axis thereof is prevented by loosely fitting the shaft hole on the shaft portion and by entering the operation lever to the slit in a state where the meshing portion assembly is not attached to the operating portion assembly.
