As shown in FIG. 9, the drive member 40 is rotated clockwise, whereby the locking lever 29 in the lock position is rotated counterclockwise to the unlock position. At this time, the connecting link 42 having one end connected to the locking lever 29 also moves upward in the figure, but the engaging pin 52 at the other end of the connecting link 42 is in the elongated hole 51 provided in the key operation input lever 41. The key operation input lever 41 is not affected from the connecting link 42. Further, when the driving member 40 rotates from the locked position to the unlocked position, no pressing force is applied from the pressing shaft 92 included in the driving member 40 to the contact protrusion 91 of the super lock link 69. Furthermore, the knob lever 61 and the joint lever 67 are also rotated to the unlocked position by the force acting on the joint lever 67 from the driving member 40 via the connecting shaft 68 by the rotation of the driving member 40 from the locked position to the unlocked position. It will be.

  Further, in the locked state shown in FIG. 8, when the super lock motor 66 is operated by, for example, executing the locking operation of the cylinder lock 16 twice within the set time, the super lock lever 86 is moved back as shown in FIG. Rotate clockwise. Thereby, the super lock link 69 slides so as to switch the connecting shaft 68 from the connected state to the non-connected state, and the super lock mechanism 65 enters the super lock on state. When the turning force to the unlocking side acts on the knob lever 61 via the push / pull cable 62 from the lock operation knob 17 in the super lock on state by the super lock mechanism 65 as described above, as shown in FIG. 61 and the joint lever 67 rotate counterclockwise, and the connection shaft 68 inserted through the connection hole 72 of the drive member 40 only moves in the circumferential hole 72b of the connection hole 72. No turning force is transmitted to the drive member 40. That is, the connection between the knob lever 61 and the drive member 40 is released by the operation of the super lock mechanism 65.

  When the door lock motor 35 is operated to the unlock side in the super lock on state by the super lock mechanism 65 shown in FIG. 10, the drive member 40 is rotated counterclockwise, thereby the locking lever in the locked position. 29 rotates clockwise to the unlock position shown in FIG. At this time, the connecting link 42 whose one end is connected to the locking lever 29 also moves upward in the figure, but the engaging pin 52 at the other end of the connecting link 42 passes through the long hole 51 of the key operation input lever 41. The key operation input lever 41 is not affected from the connecting link 42. When the driving member 40 rotates from the locked position to the unlocked position, the pressing shaft 92 provided on the driving member 40 comes into contact with the contact protrusion 91 of the super lock link 69 and slides the super lock link 69. The connecting shaft 68 is pushed by the engaging contact portion 77b of the super lock link 69 to be connected to the driving member 40. That is, when the knob lever 61 and the drive member 40 are in the non-connected state by the operation of the super lock mechanism 65, the knob member 61 and the drive member are rotated by rotating the drive member 40 to the unlock side by the operation of the door lock motor 35. 40 is connected.

  Further, when the unlocking operation of the cylinder lock 16 is performed in a super lock on state by the super lock mechanism 65, as shown in FIG. 12, the key operation input lever 41 rotates in the clockwise direction of FIG. When the engagement pin 52 engages with the key operation input lever 41 on one end side of the long hole 51 provided in the lever 41, the locking lever 29 is rotated clockwise through the connection link 42, so that the locking position is reached. The existing locking lever 29 is in the unlock position. When the locking lever 29 is rotated to the unlock position side, the pressing shaft 92 of the driving member 40 contacts the contact protrusion 91 of the super lock link 69, and the connecting shaft 68 is pushed by the super lock link 69. The connected state is established, and the knob lever 61 is also rotated to the unlock position. Also by this, the knob lever 61 and the drive member 40 are connected to each other so that the other follows the rotation to one of the lock positions.

  That is, when the knob lever 61 and the drive member 40 are not connected by the operation of the super lock mechanism 65, the knob lever 61 and the drive are driven by rotating the drive member 40 to the unlock side by the unlocking operation of the cylinder lock 16. The members 40 are connected to each other.

  In this way, even if the lock operation knob 17 disposed on the door D is improperly operated on the side facing the vehicle compartment in the locked state of the door lock device 15, the door lock device is in the super lock on state of the super lock mechanism 65. 15 is never unlocked.

  In addition, the knob lever 61 is connected to the rotation shaft 58 that supports the drive member 40 so as to be relatively rotatable, and the joint lever 67 can be slid in a direction perpendicular to the axis of the rotation shaft 58. The super lock link 69 is slidably operated in a direction parallel to the sliding direction of the joint lever 67 and is engaged with the connecting shaft 68. That is, the main functions of the super lock mechanism 65 are concentrated around the axis of the rotating shaft 58, the number of link coupling portions is reduced, and it is unnecessary to particularly increase the component dimensional accuracy and the inter-axis dimensional accuracy. The super lock mechanism 65 can be configured with a simple structure that does not require link operation, and can be easily manufactured and assembled.

  A guide portion 80 for guiding the slide operation of the super lock link 69 is provided in the actuator housing 33, and the slide operation of the super lock link 69 can be guided by the guide portion 80 and smoothed.

  Further, a metal sliding contact plate 73 that is in sliding contact with the joint lever 67 is fixed to the actuator housing 33, and a passage 74 through which the electric wires 75 are passed is formed between the sliding contact plate 73 and the actuator housing 33. The lever 67 can be smoothly rotated and slid by the sliding contact with the sliding contact plate 73 and can be used as a guide for wiring the electric wires 75.
