Because the 47b and the tooth portion 46b are in mesh with each other, the close lever
46 reverses and rotates clockwise. As a result, the close lever 46 comes into contact with and pushes into the tip portion 42a of the cam member 42.

When the cam member 42 is pushed in, a pivot shaft 34a is shown in FIG.
Swings counterclockwise around the center of the arrow, and the latch member 34 swings counterclockwise integrally with the cam member 42 to completely engage the striker 15 to reach the full latch position. As a result, the rear door 20 is restrained in the closed state.

When the latch member 34 reaches the full latch position, the contact piece of the full latch position detection switch 44 comes into contact with the large diameter surface 43a of the cam member 42 and the small diameter surface 43b. As a result, the door control unit 60 and the power feeding control unit 65 operate and the drive motor 50 rotates in the reverse direction.

When the drive motor 50 rotates in the reverse direction, the output member 54 rotates clockwise around the pivot 54a, and the connecting rod 51 is pushed in. When the connecting rod 51 is pushed in, the sector gear member 47
Swings clockwise about the pivot 47a, and the closing lever 46 reverses and rotates counterclockwise about the pivot 46a.

As a result, the closing lever 46 moves the tip portion 42 of the cam member 42.
leave from a. During this time, the connecting rod 51 receives a compressive force in the axial direction, but only the reaction force when the close lever 46 and the sector gear member 47 are simply rotated, so that the compressive force is a relatively small force. The compression force does not cause the connecting rod 51 to buckle.

The close lever 46 separates from the tip end portion 42a of the cam member 42 and eventually comes into contact with the stopper piece 31e. Before and after, the standby position detection switch 49 contacts the close lever 46 as shown in FIG.

As a result, the door control unit 60 and the power feeding control unit 65 operate and the drive motor 50 stops rotating.

When swinging the latch member 34 from the half-latch position to the full-latch position, for example, when the inside handle is operated, the operation of the inside lever 37 is detected by a reversing switch (not shown), and the detection signal is detected by the door control. Output to the unit 60, and the drive motor 50 is rotated in the reverse direction.

As a result, the closing lever 46 moves the tip portion 42 of the cam member 42.
The latch member 34 does not swing to the full latch position by retracting from a. As a result, it is safe even when an object or the like is caught in the rear door 20 and is in a half-locked state.

Although the connecting rod 51 is used as the connecting member in the above embodiment, the present invention is not limited to this, and a pulling wire may be used, for example. In that case, when the closing lever 46 returns to the standby position, the closing lever 46 is rotated by the urging force of the spring member 46c.

[Advantages of the Invention] According to the door closing device for an automobile door of the present invention, the force from the output member on the door closing device side is transmitted to the closing lever side on the locking mechanism side via the connecting member, and the closing lever operates accurately. As described above, by swingably pivoting the door closing device main body to the base member on the lock mechanism side and relatively swinging the base member and the door closing device main body, the connecting portion on the lock lever side close lever side and the door closing Since the delivery length of the output member on the device side with the connection part can be finely adjusted, for example, if the base member is fixed and the door closing device body is swung little by little, both of them can be adjusted accordingly. The transfer length between the connecting parts of the can be changed little by little and finely adjusted by a simple operation, the lock mechanism and the door closing device can be easily assembled, the number of assembling steps can be reduced, and the assembling cost can be reduced. it can.
