an actuating member that can be rotated between a locked position and an unlocked position by interlocking with the key; and a drive mechanism that rotates the actuating member to the locked position and the unlocked position when the key is used to lock and unlock the key. and a plunger that can move forward and backward to restrain the operating member in the locked position when operated.

[Function] In this configuration, the actuating member of the actuator is rotated to the locked position and the unlocked position by locking/unlocking with a key from outside the vehicle, and furthermore, the actuating member in the locked position is restrained.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS. 1 to 9.

In the figure, 1 indicates the latch of the door lock device @A.

The latch 1 is at the full latch position tlI in which the door is closed and is properly engaged with the striker 3 when the striker 3 fixed to the vehicle body enters, the half latch position - which is in the ajar state, and the full latch position tlI where the striker 3 is in the full latch position -. It is pivotable to the base plate 6 and cover plate 7 by a latch shaft 5, and is rotatable to an overtravel position (2) in which a deeper engagement occurs once. The latch 1 in the full latch position is removably engaged with the pawl 9a of the pawl 9, and its movement in the counterclockwise direction (arrow A) is restricted.

The pawl 9 is connected to an open lever 17 via a ball shaft 13, and is biased by a spring 19 interposed in the lever 17 to a position where it is constantly engaged with the latch 1 at the full latch position (2).

A protrusion 21 is formed on the open lever 17, and the protrusion 21 can be engaged with and disengaged from an engagement portion 25 formed on the sub-lever 23. The sub-lever 23 has an outside lever 27 at one end and a lock lever 2 of the locking/unlocking mechanism 15, which is rotatable between a locking position IV (dashed line in FIG. 5) and an unlocking position V (solid line in the same figure) at the other end. When the lock lever 29 is in the locked position IV, the engaging portion 25 of the sub-lever 23 is in a state separated from the protrusion 21 of the open lever 17, and the outside lever 27 or the lever 27 is
Even if you operate the inside lever 31 connected to the engaging part 25
The latch 1 and the striker 3 are kept in engagement with each other as shown by the arrow. Further, when the lock lever 29 is in the unlocked position v, the engaging portion 25 of the sub-lever 23
is engaged with the protrusion 21 of the open lever 17, and each lever 27.31 on the outside or inside
By operating , the claw portion 9a of the pawl 9 is released from the latch 1 via the open lever 17 which rotates clockwise (arrow in FIG. 5).

Switching of the lock lever 29 between the locked position IV and the unlocked position V is performed by an actuator 35 and the lock lever 2, which will be described later.
Key cylinder K connected to 9 and D knob 33 in the vehicle interior
The operation of each is controlled by

In addition, the outside lever 27 and the inside lever 3
1 is connected to an outside handle and an inside handle (both not shown) via a rod.

On the other hand, an acticoator 35 is connected to the lock lever 29.

The actuator 35 has an actuating member 37 that is rotatable between a locked position Vl and an unlocked position (2), and the actuating member 37 has a sector gear 43 fixed to the crankshaft 41 of the crank arm 39 and an actuating member 37 in a free state. The operating arm 45 is connected to the sector gear 43 by a spring 47.
Constantly biased toward the protrusion 49 rising from one edge
Figure 7, arrow c). The crank arm 39 is interlocked with the lock lever 29 through a transmission means such as a rod, and when the operating member 37 is in the locked position (2), the lock lever is in the locked position (2). Further, when the actuating member 37 is in the unlocked position (3), the lock lever 29 is set to be in the unlocked position V, and the amount of rotation of the actuating member 37 is regulated by stoppers P1° and P2 provided on the case 40. There is.

On the other hand, a drive mechanism 51 is provided in the gear portion 43a of the sector gear 43.
The small gears 53 of are meshed with each other. A large gear 57 is attached to the gear AI shaft 55 of the small gear 53 via an electromagnetic clutch (not shown), and the large gear 57 meshes with a motor gear 61 of a drive motor 59.

When the locking contacts S1 and Ll of the key switch S provided inside the key cylinder and the lock switch L provided on the passenger compartment side are closed, the drive motor 59 rotates forward through the control circuit SL to unlock the door. Contact $2 - When the 2nd side is closed, it is a forward/rain-passing motor that reverses direction via the control circuit SL.

As mentioned above, the large gear 57 and the small gear 53 are connected via the electromagnetic clutch, but the clutch is in the "α" state when the motor circuit is on, and is normally in the "disconnected" state. In this state, the operating member 37 and the drive mechanism 51 side are separated, so that the lock knob 33 can be operated in the middle chamber without any hindrance.

Further, a lock contact M is provided inside the key cylinder and is closed when the key is fully inserted. The lock contact M is connected to the solenoid 63 via the control circuit SL, and when the lock contact M is opened, the solenoid 63 operates and the plunger 65 retreats (arrow).
Figure 7 solid line). Further, after the solenoid 63 is activated, it is turned off after a certain period of time by the control circuit SL. As a result, the plunger 65 is moved by the action of the spring 67 to the actuating arm 4.
It protrudes to the operating state IX (solid line in Fig. 9) facing the rotation locus line of No. 5.

In the circuit shown in FIG. 6, the motor 59 of the actuator 35 is for one side of the front door, and the same applies to other doors (not shown).

In the door rotor operation device with an actuator configured as described above, when a locking operation is performed by selecting the lock knob 33 or the lock switch L in the vehicle interior, the lock lever is activated.
29 and the actuating member 37 are in the locked position IV.■. At this time, the operating lever 45 interferes with the plunger 1265 as shown in FIG. 29 and actuating member 37
are interlocked and return to the unlocked positions V and ■, respectively, allowing locking and unlocking operations to be performed without any trouble.

Next, when leaving the car, the key is inserted into the key cylinder I, a lock detection is performed, and then a locking operation is performed. At this time, first, after the [-1 ivy contact M is closed, the locking contact S
1 closes J: Unaru. Therefore, as shown in FIG. 7, following the non-operating state (2) in which the plunger 65 is retracted, the actuating member 37 rotates to the locked position (1). Actuation member 37
After the locking position vI, the plunger 65 again protrudes to the operating state IX as shown in FIG. 9, and can engage with the operating lever 45 so as to prevent the operating lever 450 from rotating clockwise. As a result, the movement of the actuating member 37 in the unlocking direction (arrow 2 in FIG. 9) is restricted due to the engagement between the protrusion 49 and the actuating lever 45, so that wires and thin plates cannot be removed from the door waist portion or the like. Insert it and operate the lock lever 29T.
It will no longer be unlocked.

Furthermore, even if an attempt is made to unlock the vehicle by operating the lock switch L in the vehicle interior due to a fraudulent act such as breaking a window glass, the plunger 65 will not retreat to the non-operating state. "Movement to" is restricted and cannot be unlocked!

Next, to release the lock, insert the key and retract the plunger 65 to the inactive state ■, then perform the release ↓;1 operation and 2. Open the unlock contact $2. As a result, the operating member 37 and the lock lever 29 are unlocked 1+> ii V
