In this state, the operation force transmission path between the vehicle outer side operation handle and the release member (6) is cut off, and the space between the vehicle interior side operation handle and the release member (6) and between the lock knob and the first disengagement member (6). Although each operation force transmission path between the lock means (10) and the locking means (10) is connected, the door cannot be opened by opening the vehicle outside operation handle, but the first operation is performed by opening the door inside operation handle. It is possible to perform an overriding operation that can always open the door regardless of the state of the locking means (10). Further, by the locking / unlocking operation of the lock knob, the first locking / unlocking means (10) can be switched to each state in the same manner as described above.

That is, when the vehicle outside operation handle is operated, the first locking / unlocking means (10) is in the locked state,
The release part (15b) of the sub-lever (15) is the engagement part of the release member (6).
Since it is not possible to engage with (6b), the operating force of the vehicle outside operation handle cannot be released and the release member (6) cannot be operated, and the door cannot be opened.

When the operation handle on the inside of the vehicle is operated, the second locking / unlocking means (21) is in the unlocked state. Therefore, regardless of the state of the first locking / unlocking means (10), The operating force passes through the operating force transmission path similar to the above, and the release member
The door can be opened by being transmitted to (6). Also,
At this time, the operation of the operating handle on the inside of the vehicle
Detected by (not shown), the first motor (36) is driven in the unlocking direction to switch the first locking / unlocking means (10) from the locked state to the unlocked state.

In this state, in the super lock state, the operation force transmission path between the vehicle outside operation handle and the release member (6), the operation force transmission path between the vehicle inside operation handle and the release member (6), Since all the operating force transmission paths between the lock knob and the first locking / unlocking means (10) are cut off, the door can be opened by any opening operation of the vehicle outside operation handle or the vehicle inside operation handle. In addition, the lock / unlock operation of the lock knob cannot switch the first locking / unlocking means (10) to the unlocked state.

Therefore, in this super-locked state, the door cannot be opened even if the vehicle-side operation handle, the vehicle-side operation handle, and the lock knob are attacked by a fraudulent act.

That is, when the vehicle outside operation handle is operated, the door cannot be opened in the same manner as above because the first locking / unlocking means (10) is in the locked state.

When the operation handle on the inside of the vehicle is operated, the second locking / unlocking means (21) is in the locked state, and the engaging portion (22c) of the inside lever system engaging / disengaging lever (22) is in the second out position. Since the side lever (9) cannot engage with the release part (9b), the operating force of the in-vehicle operation handle does not act on the release member (6) and the door cannot be opened. Can not.

When the lock knob is unlocked, the third locking / unlocking means (29) is in the locked state, and the engagement / disengagement portion (30b) of the knob lever system engagement / disengagement member (30) is moved by the moving member (16). Engagement groove (16b)
Therefore, even if the knob lever (26) rotates from the locked position to the unlocked position, the knob lever system engagement / disengagement lever (30) swings against the moving member (16), as shown in FIG. 11. Moreover, only the knob lever (26) and the knob lever system engagement / disengagement lever (30) move to the unlocking position, and the unlocking operation force of the lock knob cannot be transmitted to the first locking / unlocking means (10). Therefore, even if the lock knob is unlocked by cheating,
The first locking / unlocking means (10) cannot be switched to the unlocked state.

The cancellation of the super lock state is performed by unlocking the remote control switch. That is, when the remote control switch is operated, first, the second motor (24) is driven to move the switching lever (23) from the locking position to the unlocking position to unlock the second locking / unlocking means (21). Switch to the locked state.

At the same time, the control lever (32) is moved to the unlocked position by moving the switching lever (23) to the unlocked position, so that the engagement / disengagement portion (30) of the knob lever system engagement / disengagement lever (30). 30b) is fitted in the engagement / disengagement groove (16b) of the moving member (16) by the urging force of the spring (34), and the third locking / unlocking means (29) is unlocked. Then, the first motor (36) is driven to move the moving member (16) from the locking position to the unlocking position, and the first locking / unlocking means (10) is unlocked.

When the key cylinder is unlocked,
By rotating the first locking / unlocking lever (12) from the neutral position in the unlocking direction, the first locking / unlocking means (10) is switched from the locked state to the unlocked state, and the emergency lever (38) is turned on. The control lever (32) is moved from the locking position to the unlocking position via the second locking / unlocking means (2
1) and the third locking / unlocking means (29) are switched from the locked state to the unlocked state.

Therefore, in the super lock state, even if the first motor (36) and the second motor (24) cannot be driven due to battery exhaustion or the like, the first, 2 and 3rd locking / unlocking means (1
All of 0) (21) (29) can be unlocked.

Although one embodiment of the present invention has been described above, various modifications and changes can be made to the above embodiment without departing from the scope of the present invention.

For example, the releasing member (6) and the locking plate (3) are integrated, the second locking / unlocking means (21) and the third
It is possible to use a separate electric drive source from the locking / unlocking means (29), an electromagnetic solenoid, and the like.
