(Operation) Next, the operation will be described.

When the key cylinder 10 of the driver's door lock device is not operated by a key, the key cylinder 10 is located at the center by the action of the spring 10a, and the center return spring arc cover 15 is provided.
The two ends of the center return spring 18 provided in the arc groove 19 on the inner surface of the switch arc cover 16 and the protrusions 22 and 23 at the inner end of the switch arc cover 16 3 and 4, the center return spring arc cover 15 is in the position directly above and the switch arc cover 16 is in the position directly below, as shown in FIGS. The mounted moving contact 25 is located directly below, contacts only the center contact 26, does not contact the left and right fixed contacts 26, 27, is neutral and is not energized. Locked.

Therefore, the key cylinder is operated as usual by operating the key 12.
When the 10 is rotated to the left and right by about 45 °, the driver can lock the driver's door lock by turning it clockwise, and unlock the driver's door lock by turning it counterclockwise. At this time, key cylinder 10
The rotating piece 13 fixed to the rear end also rotates left and right by about 45 °, but since the rotating piece 13 only comes into contact with the projection 29 and does not push, it also rotates to the switch arc cover 16 side. The moving contact 25 remains at the position directly below, does not contact the left and right fixed contacts 26 and 27, and maintains neutral.

Then, by the key operation, the rotating piece 13
After colliding with 29, it is further rotated to the right.
The projection 30 is pressed by the projection 31 of the center return spring arc cover 15 and the switch arc cover to which the projection 30 is fixed.
As shown in FIG. 6, the switch 16 is rotated clockwise until the protrusion 35 on the inside of the switch arc cover 16 hits the protrusion 21 of the outer fixed tubular portion 1 and stops. Then, the center return spring 18 is pressed by the projection 23 and contracts, and the moving contact 25 is made of the center contact 26 and the left fixed contact.
The power is applied to both of the seats 27 and 27, and the actuators of the other passenger seats and the rear seats are also energized to lock the lock levers of the locking devices of the other seats.

Conversely, the key 13 causes the turning piece 13 to move
After turning to the left after colliding with
The center return spring arc cover 15 and the switch arc cover 16 to which the projection 29 is pressed by the projection 31 of the
5 as shown in FIG.
36 is rotated until it stops after hitting the protrusion 21 of the outer fixed cylindrical portion 1. Then, the center return spring 18 is pressed by the projection 22 and contracts, and the moving contact 25 contacts both the center contact 26 and the right fixed contact 28 to energize, and energizes other actuators in the front passenger seat and the rear seat. Also, the lock lever of the lock device of the other seat is also unlocked.

Thus, the key switch of the present invention is a key cylinder.
When 10 is rotated left and right by 45 °, the driver's door is locked and unlocked,
The doors other than the driver's door are locked and unlocked by rotating the driver's door 90 ° each time.This is because the inner door handle of the locked driver's door is opened and the driver's door is moved in one motion. When the door is opened, there is an effect that other doors are not unlocked.

That is, a normal driver's seat lock device can open the door as it is by opening the inner door handle even in the locked state, and simultaneously displaces the locked lock lever to the unlocked state when the door is opened. Then, in conjunction with this, the other doors simultaneously displace the lock lever in the locked state to the unlocked state. However, even if the driver's seat door is opened with one motion opening, the key cylinder accompanying it is Since the rotation of the rotation piece 13 of 10 can be performed only by 45 ° left and right, the range of rotation of the rotation piece 13 is the left and right protrusions 29 and 30.
, The key cylinder 10 is not rotated any further, so that other doors are not unlocked. Therefore, it is safe to put the child in the back seat.

(Effect) The present invention provides an outer fixed cylindrical portion 1 fixed to a driver's seat door,
A key cylinder 10 provided in the outer fixed cylindrical portion 1 and rotated left and right by a key operation; a central contact 26 and a left fixed contact 27 attached to the outer fixed cylindrical portion 1 and arranged in a circumferential direction;

The rotating member P locks or unlocks the driver's seat door by rotating the key cylinder 10 left and right by key operation. When it is rotated further than the lock of the driver's seat door, the rotating member P rotates and the center contact 26 and the left fixed contact 27 are joined to lock the other doors. When the rotating member P is further rotated beyond the unlocking state of the seat door, the rotating member P rotates and the central contact 26 and the right fixed contact 28 are connected to unlock the other door. Because of the mechanism, Keith of the driver's seat door conventionally known Unlike the switch mechanism, turning the key to the right locks the driver's door, turning the key to the right locks other doors, and turning the key to the left unlocks the driver's door. If the lock and the key are further turned to the left, the doors of the other seats are unlocked, so that there is no erroneous operation even with unconscious operation. and,
Simple structure and easy handling. A conventionally known key switch mechanism of a driver's seat door locks the driver's seat door by rotating the key to the right, locks the door of another seat by rotating the key to the left, and turns the key to the right to drive the key. When the seat door is unlocked and the key is rotated to the left and pressed, the other doors are unlocked, so there is no distinction between the key rotation direction and the locking / unlocking.

The present invention also provides an outer fixed cylinder portion 1 fixed to a driver's seat door, a key cylinder 10 mounted in the outer fixed cylinder portion 1 and rotated left and right by a key operation;
