1. A door lock apparatus comprising:

  • a latch mechanism that restricts movement of a door in an open direction by latching when the door is in a closed position with respect to a vehicle main body;

    a link lever that swings between a cancel position and a non-cancel position, the link lever allowing movement of the door in the open direction by cancelling a latched state of the latch mechanism when moved upwards while being disposed in the cancel position, the link lever maintaining the latched state of the latch mechanism when moved upwards while being disposed in the non-cancel position;

    a sector lever shaft and an inside lever shaft that are disposed on both sides of the link lever and extend in parallel with a swinging shaft of the link lever;

    a sector lever that is swingably disposed between an unlocked position and a locked position about the sector lever shaft, the sector lever moving the link lever to the cancel position while in the unlocked position, and moving the link lever to the non-cancel position while in the locked position; and

    an inside handle lever that is swingably disposed about the inside lever shaft, the inside handle lever moving the link lever upward by swinging about a center of the inside lever shaft when an inside door handle arranged inside a vehicle is open-operated while the link lever is being positioned in the cancel position, and swinging the sector lever in the locked position to the unlocked position by swinging about the center of the inside lever shaft when the inside door handle is open-operated while the link lever is being positioned in the non-cancel position.
