The door-closing cable (12b) is guided by the second rear pulley (29) below, inserted into the cable guide groove (5b) from the rear end of the guide track (5), and extends forward to guide the track. At the front end of (5), the first front pulley (22) guides the vehicle rearward in a U-turn shape,
It extends rearward in (5) and is a connecting part (36) of the moving member (35).
It is connected to.

As shown in FIG. 14, the door opening cable (12a)
And the terminal members (12c) (12d) fixed to the respective terminals of the door closing cable (12b), so as to face each other,
It is slidably fitted in the connecting portion (36). Each terminal member
Between the (12c) and (12d) and the end of the connecting portion (36), the door opening cable (12a) and the door closing cable (12b) are urged in the tensioning directions to absorb the slack. Coil spring
(43) are each reduced.

The moving member (35) is connected to the door (2) through a hinge bracket (39), and the motor (1) of the door driving unit (10) is connected to the moving member (35).
By the pulling force of the door opening cable (12a) or the door closing cable (12b) due to the rotation of 3), the guide track (5) is moved forward or backward, and the door (2) is opened or closed. To move.

The hinge bracket (39) is a rail side arm (39a) connected to the base plate (35a) of the moving member (35).
And a door side arm (39b) rotatably connected to the rail side arm (39a) with a shaft (41) and coupled to the door (2), and the guide track (5) from the inside to the vehicle body. panel
Through the mounting hole (1c) of (1), the recess (1b) of the vehicle body panel (1)
After fixing the rail side arm (39a) to the base plate (35a) with a bolt (40).

The base plate (35a) and the rail side arm (39
The hinge member (39) moving member (3
The concave portion (39c) and the convex portion (35d) for alignment with respect to 5) are
Each is formed in two places.

The door moving device (10) is assembled by connecting the door driving section (11), the guide track (5) and the door driving cable member (12) to each other before mounting on the vehicle. In this assembled state, the front end of the guide track (5) is inserted from the indoor side into the mounting hole (1c), and the guide track (5) and the door drive cable member (12) are passed outside the room,
Hold the guide track (5) with the bolts (44) on the body panel.
It is fixed in the recess (1b) of (1) and also the door drive (11)
To the vehicle body panel (1) on the indoor side.

After fixing the guide track (5) to the vehicle body panel (1), the hinge bracket (39) is attached to the base plate (35a) of the moving member (35) slidably provided on the guide track (5). Secure with bolts (40).

Then, the hinge bracket (39) is connected to the slide door (2) which is openably and closably supported by the upper track (3) and the lower track (4) fixed to the vehicle body panel (1). The door (2) and the door drive part (11) are
It is connected via a door drive cable member (12). Therefore, the guide track (5) has a large hinge bracket (39).
Since the vehicle body panel (1) is not attached, the mounting hole (1c) formed in the vehicle body panel (1) is attached to the moving member (3
Only the size of 6) needs to be assembled, an extremely small opening amount is sufficient, and the number of holes to be drilled is only one.

In the fully closed state shown in FIG. 4, the door is locked by opening the operation switch provided near the driver's seat.
The engagement between (2a) and the striker is released, and at the same time when the motor (13) rotates in the normal direction, the electromagnetic clutch provided in the speed reduction section (14) is excited, and the rotational force of the motor (13) is driven by the drive pulley. , The door opening cable (12a) is caught, and the door closing cable (12b) is sent out. Due to the winding of the door opening cable (12a), the door opening cable (12a) is pulled in the guide track (5), and the moving member (3
The door (2) is forcibly moved in the opening direction by moving 5) in the opening direction.

When the door (2) reaches just before the fully open position, the detecting rod (32a) of the slider (32) is pushed by the moving member (35) to move from the projecting position shown in FIG. 16 to the retracted position. As a result, the check switch (34) detects the fully open position of the door (2), shuts off the power supply to the motor (13) and the electromagnetic clutch, and the door (2) is stopped at the fully open position.

Further, in the fully opened state shown in FIG. 5, the operation of closing the operation switch causes the motor (13) to rotate in the reverse direction, and at the same time, the electromagnetic clutch is excited to transmit the rotational force of the motor (13) to the drive pulley. The door closing cable (12b) is caught and the door opening cable (12a) is sent out.

By winding the closing door cable (12b),
The door closing cable (12b) is connected to the guide groove of the guide track (5).
It is pulled through the guide track (5) through (5b). Accordingly, the moving member (35) is guided by
The bottom piece (5c) of (5) rolls and moves in the door opening direction, and the door (2) is forcibly moved in the door closing direction. Since the guide track (5) is integrally formed with the cable guide groove (5d) to increase the section modulus and improve the rigidity, the guide track (5) is influenced by the weight of the door (2). The bending of the moving member (35) is suppressed, and the moving member (35) can be smoothly moved.

When the door (2) reaches the fully closed position, the door lock (2a) engages with the striker and is held at the fully closed position, and a fully closed detection switch (not shown) for detecting the engagement of the door lock. ) Shuts off the power supply to the motor (13) and the electromagnetic clutch.

[0039]

According to the present invention, the following effects can be obtained. (a) Since the track portion that movably accommodates the moving member in the guide track and the cable guide groove that guides the cable are integrally formed, the door driving cable member can be routed before the vehicle body is assembled. Therefore, the wiring work can be easily performed, and the work efficiency and accuracy of connecting the slide door and the door drive cable member can be improved.

(B) By integrally forming the track portion and the cable guide groove in the guide track, the section modulus of the guide track increases and the rigidity of the entire guide track increases, and the bottom piece is reinforced to increase the rigidity of the door. The bending due to the weight can be prevented, and the door can be smoothly opened and closed.
