Abstract:
1. A door lock device for holding a door in a fully-closed state, said door being capable of being opened and closed relative to a vehicle body, said door lock device comprising: a base plate and a striker which are installed to one and the other of said door and said vehicle body; a hook which is supported by said base plate to be rotatable between a striker holding position for holding said striker, a striker releasing position for releasing said striker and a draw-in commencement position between said striker holding position and said striker releasing position, said hook being biased toward said striker releasing position; a closing lever which is supported by said base plate thereon to be coaxially rotatable with said hook and rotates between a draw-in position, at which said closing lever is positioned toward said striker holding position of said hook, and a draw-in releasing position, at which said closing lever is positioned toward said striker releasing position of said hook; a motor-operated driving mechanism provided with a motor which does not operate when said hook is located at a position toward said striker releasing position from said draw-in commencement position, and which operates to rotate said closing lever to said draw-in position when said hook moves to said draw-in commencement position from said striker releasing position and wherein when said motor drive mechanism is in direct contact with said closing lever such that said closing lever is directly pressed and rotated by said motor drive mechanism; a closing/control lever biaser comprising a spring which biases said closing lever toward said draw-in releasing position at all times; an interlinking lever which is in direct connection with said closing lever such that said interlinking lever is pivoted on said closing lever and rotatable between a coupling position at which said interlinking lever is engaged with said hook so as to make said closing lever and said hook integral with each other via said interlinking lever, and a coupling disengaging position at which said interlinking lever is disengaged from said hook to allow said closing lever and said hook to rotate relative to each other; a control lever which is rotatably supported by said base plate thereon and rotates between a coupling assisting position and a coupling-disengagement assisting position; wherein said closing/control lever biaser biases said control lever toward said coupling assisting position; a control slot which is composed of an elongated hole formed in said control lever, in which a control projection of the interlinking lever is engaged to be movable relative to said control slot, which moves said interlinking lever toward said coupling position via said control projection when said control lever rotates toward said coupling assisting position, and which moves said interlinking lever toward said coupling disengaging position via said control projection when said control lever rotates toward said coupling-disengagement assisting position; and a stopper which prevents said closing lever, rotated to said draw-in releasing position, from rotating by a biasing force of said closing/control lever biaser to thereby make said control projection spaced from an end surface of said control slot in a lengthwise direction thereof.
