BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for operating a door opening / closing operator suitable for a vehicle body or the like that has been subjected to a smoothing process which has become popular among young people. The present invention relates to a device for operating a door opening / closing operation device, wherein the operation of a door opening / closing operation device is performed using a motor.

2. Description of the Related Art In recent years, it has become popular among some young people to customize the outer surface of a commercially available vehicle body by a smoothing process, and specializing in such a smoothed vehicle. Remodeling companies that sell to the United States have also emerged nationwide.

FIG. 7 (a) is a perspective view of the vehicle body before smoothing with respect to the rear door as viewed obliquely from the rear, and FIG. 7 (b) is a perspective view of the vehicle body after smoothing with respect to the rear door which is viewed from the oblique rear. Respectively. In these figures, a is a rear door, b is a license plate, c is a rectangular recess for attaching a license plate, d
Is a door opening / closing lever for manual operation used for opening / closing the rear door, e is a rear bumper, and f is a rear window. As is clear from FIG. 7A, before the smoothing process, the rear door a has a recess c for attaching a license plate b. A door opening / closing lever d, which is an operation element for opening / closing the rear door, is provided at an upper inner peripheral portion of the concave portion c. On the other hand, as is clear from FIG. 3B, in the state after the smoothing process, the surface of the rear door a has no irregularities at all, and is in a smooth state. It has been moved to the rear bumper e. For this reason, after the smoothing process, the vehicle body has a unique appearance unlike a commercially available vehicle body, and this is considered to attract young people.

By the way, as apparent from a comparison between FIG. 7A and FIG. 7B, when such a smoothing process is performed, the concave portion c for accommodating the license plate b is used for opening and closing the door. The rear door a can no longer be manually opened from outside the vehicle by using the lever d because the rear door a is buried and hidden together with the lever d. Therefore, in order to open and close the rear door that has been subjected to the smoothing process, an operation substitute device called a "rear gate opener" or the like has been conventionally used.

Before moving on to a description of a conventional operation substitute device, a general mooring structure of this kind of rear door to a vehicle body will be briefly described with reference to FIG. In FIG.
g is a mooring locking portion on the vehicle body side, h is a mooring device on the door side called "catch" or the like, i is a control lever for controlling the mooring device h between a latchable state and a non-latchable state, j Is a link rod mechanism for transmitting the movement of the operating lever d for opening and closing the rear door to the control lever i of the mooring device h, k is the door outer panel, l is the door inner panel, m is an arrow indicating the opening and closing direction of the rear door, n Is an arrow indicating the operation direction of the link rod mechanism.

The mooring locking portion g is usually attached to the center of the rearmost end of the floor of the vehicle body, and its specific shape is not limited to the illustrated ring shape but various shapes such as a hook shape. Exists. The mooring device (commonly called “catch”) h is connected to the mooring locking portion g to moor the closed rear door a to the vehicle body. ].

Here, the latchable state means a state in which when the rear door is closed, the mooring locking portion g is received and locked or engaged with the mooring locking portion g so that it cannot be disengaged. The non-detachable state includes an incompletely-tethered state generally referred to as a "half door" or the like and a fully-tethered state in which the door cannot be released when the door is completely closed. On the other hand, the state that cannot be latched is
Even if the rear door is closed, the mooring lock g is received, but is not locked or engaged with the mooring lock g. When the rear door is opened, the mooring lock g is always free. To be able to leave.

The control lever i is normally pivotally supported up and down with an internal shaft as a fulcrum, and is urged by a fairly strong spring in either the up or down direction. In a state where the control lever i is rotated in the direction biased by the spring, the mooring device h is set in a latchable state. On the other hand, when the control lever i is rotated in the direction opposite to the direction urged by the spring, the mooring device is set in a non-latchable state.

In the example shown in FIG. 8, the control lever i is normally urged upward by a spring, and in this state, the mooring device h is set in a latchable state. For this reason, in order to open the rear door a and switch the operation state of the mooring device h from the latchable state to the non-latchable state, the control lever i is pressed against the force of the spring.
It must be pushed down and held in that state. This operation of pushing down the control lever i against the force of the spring and holding it in that state transmits the force from the operating lever d for opening and closing the rear door to the control lever i via the link rod mechanism j. It is done by that.

In the illustrated example, the link rod mechanism j is depicted by a single link rod. However, in actuality, the control lever i of the mooring device h is finally connected to a plurality of link rods by a spring. To push it down against the urging force. In another example (not shown), the control lever i is normally urged downward by a spring, and in this state, the mooring device h is set to a latchable state. In such a case, in order to switch the state of the mooring device h from the latchable state to the non-latchable state, the control lever i is pulled upward against the force of the spring, and the state is switched to the state. Must be retained.
The operation of pulling the control lever i upward against the force of the spring and holding the control lever i upward is performed by applying an upward force from the operation lever d for opening and closing the rear door to the control lever i via a wire. Done in Further, there are various specific forms of the rear door opening / closing operation element such as a lever type, a push button type, and a grip type. However, according to the observation of the present inventor, most of the mooring devices h
In, regardless of the form of the rear door opening and closing control,
Either a method in which the control lever i is depressed by the link rod mechanism to set it to the unlatchable state, or a method in which the control lever i is pulled up by the wire to set the latchable state is adopted.

Next, based on the above-mentioned prior knowledge, a description will be given of a conventional operation substitute device for a rear door opening / closing operator. The basic function of the operation proxy device is to push down the link rod instead of the operation force from the operation lever d, or
By pulling up the wire, the control lever i is moved against the spring, and the mooring device h is set to the latch-disabled state (the door can be opened). In order to achieve such a function, a solenoid plunger is employed as an initial operation substitute device. The solenoid plunger is mounted in a door space surrounded by an outer panel k and an inner panel l, and a link rod for pushing down the control lever i or a wire for raising the control lever i is connected to the tip of the plunger. You. When power is supplied to the solenoid plunger, the plunger protrudes or retracts within a predetermined stroke range, and the link rod is pushed down or the wire is pulled.

[0012]

However, such a proxy operating device for operating a rear door opening / closing lever using a solenoid plunger has the following disadvantages.

[0013] Depressing or pulling the control lever i of the mooring device h against the spring requires a large and expensive solenoid plunger with a considerably large driving force and operating stroke.

Since the solenoid plunger itself is not provided with an operation holding function, in order to hold the mooring device h in a non-latchable state, it is necessary to continuously supply a current to the solenoid during that time. Therefore, when the power switch is installed so that it is not so noticeable within the reach of the rear door on the outer surface of the vehicle body and the rear door is opened,
This switch must be kept pressed.
In addition, unless some kind of electric interlock or locking mechanism is adopted, there is a possibility that anyone can operate the switch from outside the vehicle to set the mooring device h of the rear door to the unlatchable state and open the door.

If a self-holding circuit using a relay is employed, the operation of the solenoid plunger can be electrically held. However, even in such a case, the current continues to flow through the solenoid while the operation is held. If the operation is forgotten or if the energized state is continued for a long time for some reason, there is a possibility that the battery for the vehicle will be consumed quickly, or in an installation environment where heat radiation is poor, there is a risk of burning due to overheating.

After the control lever i is pushed down to its lower limit or pulled up to its upper limit, a latch mechanism for keeping the control lever i at that position even when the power to the solenoid is cut off is separately moored. Incorporation into the device h is also conceivable, but in this case, the balance between the strength of the spring supporting the latched state and the strength of the return spring of the control lever i becomes delicate, and it takes time to design.
In addition, since the specifications of the mooring device are different for each product, it is necessary to individually design the mooring device according to each vehicle type, and the versatility is poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the conventional operation device for operating a door opening / closing operator, and a purpose thereof is to set a mooring device to a state where latching is impossible. In addition to generating sufficient linear driving force to enable the necessary link rod pushing-down operation and wire pulling operation, ensure that the pushing-down operation and the pulling operation are maintained without power supply. Another object of the present invention is to provide an operation proxy device for a door opening / closing operation element which can be manufactured, has a simple structure, and is small and inexpensive to manufacture.

[0018]

The invention described in claim 1 of the present application is mounted in a vehicle door so as to be interposed in a transmission path for transmitting the movement of a door opening / closing operation element to a door-side mooring device. Acting as a door opening / closing manipulator for setting the door-side mooring device to an equivalent state when an operator load is released and an equivalent state when a non-latchable operator load is applied to the mooring locking portion on the vehicle body side. A device, a motor as a rotational power source, a speed reducer for reducing the rotational force obtained from the motor, and converting the rotational motion obtained from the speed reducer into a linear motion within a predetermined stroke range, thereby forming the transmission path. A motion conversion mechanism that transmits the link to the link rod or wire, wherein the motion conversion mechanism converts the one-way rotational motion obtained from the deceleration into a reciprocating linear motion having a constant stroke. The door-side mooring device is set to the equivalent state when the operator load is released in conjunction with the movement in one direction of the linear motion within the predetermined stroke range, while the other of the linear motions is set. By setting the door-side mooring device in an equivalent state when an operator load is applied in conjunction with the movement in the direction of, the power supply to the motor is cut off in this state, and the speed reducer and the motion conversion are performed. By the reverse rotation preventing force obtained via the mechanism, the door-side mooring device can be held in an equivalent state when the operator load is applied while resisting the return spring in the door-side mooring device even after the power supply is stopped. And a door opening / closing operation device.

According to the first aspect of the present invention, the rotational driving force obtained from the motor is transmitted to the motion converting mechanism via the speed reducer and is converted into a linear driving force. However, when a small-sized motor with a small capacity can obtain a sufficiently large linear driving force, when the motor is viewed from the load side, the reverse rotation preventing force of the motor is reduced due to the presence of the motion conversion mechanism and the reduction gear. The linear movement is kept at the same position even when the power supply to the motor is cut off. As a result, even if the control lever of the mooring device is biased by a considerably strong return spring, it must be reliably moved against the spring and set to an equivalent state when a non-latching operator load is applied. By stopping the power supply to the motor in that state, the mooring device is held in a non-latchable state by the above-described reverse rotation preventing force of the motor while resisting the spring. Without falling into the state, the connection between the mooring device and the vehicle body side locking portion is surely released, and the door can be opened. In addition, if the equivalent state is set when the operator load is released, the door-side mooring device returns to the latchable state. When the door is pressed against the vehicle body in this state, the door-side mooring device is locked to the vehicle-side mooring lock. Latching by itself, the door can be securely fixed to the car body.

Further, according to the first aspect of the present invention, it is not necessary to use a forward / reverse conversion circuit of a motor in order to obtain a reciprocating linear motion with a constant stroke, and the circuit configuration is simplified to further increase the cost. Down can be planned.

According to a second aspect of the present invention, the door mooring device is mounted in the vehicle door so as to be interposed in a transmission path for transmitting the movement of the door opening / closing operator to the door mooring device. An operation proxy device for a door opening / closing operator that sets an equivalent state when an operator load is released and an equivalent state when a non-latchable operator load is applied to a mooring locking portion on a vehicle body side, A motor as a power source, a speed reducer that reduces the rotational force obtained from the motor, and a link rod or wire that converts the rotational motion obtained from the speed reducer into a linear motion within a predetermined stroke range to form the transmission path. And a motion conversion mechanism that transmits the end of the rod to a predetermined length when the transmission path is formed by a link rod, and the transmission path is Wa And a wire locking portion for locking the wire when the door is constructed, and the door is linked with a movement in one of linear motions within the predetermined stroke range. While the side mooring device is set to the equivalent state when the operator load is released, the door-side mooring device is set to the equivalent state when the operator load is applied in conjunction with the movement in the other direction of the linear motion. In addition, by stopping the power supply to the motor in that state, the reverse rotation preventing force obtained through the speed reducer and the motion conversion mechanism prevents the return spring in the door-side mooring device even after the power supply is stopped. The door-side mooring device can be held in an equivalent state when an operator load is applied, while maintaining the door-side mooring device.

According to the second aspect of the present invention, the rotational driving force obtained from the motor is transmitted to the motion converting mechanism via the speed reducer and is converted into a linear driving force. While a small linear motor with a small capacity can provide a sufficiently large linear drive force, when the motor is viewed from the load side in reverse, the reverse rotation prevention force of the motor is significantly reduced due to the presence of the motion conversion mechanism and the reduction gear. Therefore, even if the power supply to the motor is cut off, the linear motion is maintained at the same position. As a result, even if the control lever of the mooring device is biased by a considerably strong return spring, it must be reliably moved against the spring and set to an equivalent state when a non-latching operator load is applied. By stopping the power supply to the motor in that state, the mooring device is held in a non-latchable state by the above-described reverse rotation preventing force of the motor while resisting the spring. Without falling into the state, the connection between the mooring device and the vehicle body side locking portion is surely released, and the door can be opened. In addition, if the equivalent state is set when the operator load is released, the door-side mooring device returns to the latchable state. When the door is pressed against the vehicle body in this state, the door-side mooring device is locked to the vehicle-side mooring lock. Latching by itself, the door can be securely fixed to the car body.

Further, according to the second aspect of the present invention, it is not necessary to separately prepare a special coupling tool for driving the link rod or the wire by the linear motion obtained through the motion conversion mechanism. Therefore, the degree of freedom for adaptation to various mooring devices can be increased.

According to a third aspect of the present invention, in the motion conversion mechanism, a first limit switch that operates at one end of the stroke and a second limit switch that operates at the other end of the stroke. The operation proxy device for a door opening / closing operation device according to claim 1 or 2, further comprising:

According to the third aspect of the present invention, since it is possible to reliably detect that the link rod is being pushed down or the wire is being pulled, the power supply time of the motor is appropriately controlled using this. I can do it.

The rotary motion in one direction obtained from the machine is converted into a reciprocating linear motion having a fixed stroke, and the door-side mooring device is linked to the motion in one direction of the linear motion in the predetermined stroke range. Is set to the equivalent state when the operator load is released, and the door-side mooring device is set to the equivalent state when the operator load is applied in conjunction with the movement in the other direction of the linear movement.

(Equivalent state), so even if the rear lever of the rear door is covered with the door lever or door knob as a result of smoothing the rear part of the vehicle body, for example, simply open the door with your hand on the surface of the rear door The rear door can be easily opened by simply applying force in the direction. In addition, since the equivalent state at the time of applying the operator load is continued until the close switch is operated, even if the rear door is closed by mistake, the door-side mooring device does not latch to the vehicle-side mooring locking portion. In addition, in the equivalent state when the operator load is applied, the force against the return spring in the mooring device is obtained via the speed reducer and the motion conversion mechanism, and therefore, as in the case where the conventional solenoid plunger is used. There is no need to keep the current flowing. Therefore, even if the rear door is left open for a long time,

On the other hand, by operating the close switch, the door-side mooring device of the rear door can be set to a state equivalent to releasing the door lever or door knob (equivalent state when the operator load is released), so that the rear door can be pressed against the vehicle body as it is. For example, the door is firmly fixed to the vehicle body by latching the door-side mooring device and the vehicle-side mooring locking portion independently.

FIG. 4 shows the mooring device 7 set to the unlatched state by pushing down the link rod, and FIG. 5 shows the mooring device 8 set to the unlatched state by pulling up the wire. .

First, the case of FIG. 4 will be described. In the figure, a door-side mooring device (commonly called “catch”) 7 is attached to, for example, a lower end portion of a rear door. This mooring device 7
Is provided with a locking portion receiving port 7b for receiving a mooring locking portion (not shown) on the vehicle body side, and a control lever 7a. The control lever 7a is rotatably supported in the vertical direction and is normally urged upward by a strong spring. When the control lever 7a is at the upper end position, the mooring device 7 is set in a latchable state.
When the rear door is closed in the latchable state, the vehicle body side locking portion that enters from the locking portion receiving port 7b locks or meshes with the claw inside the mooring device and cannot be removed. On the other hand, when the control lever 7a is pushed down to the lower end position, the mooring device 7 is set in a state in which latching is not possible. In a state where the latching is not possible, the locking or engagement between the vehicle body side locking member and the claw mechanism inside the mooring device is released, and the vehicle body side locking portion can be disengaged from the mooring device 7, thereby opening the rear door. Becomes possible.

In a commercially available vehicle, the operation of the mooring device 7 is controlled by transmitting the force from the operating lever for opening and closing the rear door to the control lever 7a of the mooring device 7 via the link rod 9. That is, the control lever 7a is normally urged to the upper end position by the force of the spring, so that the mooring device 7 can be latched. However, when the opening / closing operation lever is pulled with a fingertip to open the rear door. The movement is transmitted to the link rod 9 and the control lever 7a is pushed down, so that the mooring device 7 is in a state where it cannot be latched.

On the other hand, in the case of a vehicle in which the rear door has been smoothed, the operation lever for opening and closing the rear door is not used. Therefore, as shown in FIG. 4B, the link rod 9 is cut in the middle, and the cut end portion 9a is connected to the bottomed cylindrical output shaft 619 which moves up and down integrally with the slider 613, so that the lower opening is formed. The connection from the operation substitute device (motion conversion mechanism 6) mounted in the rear door to the link rod 9 is performed by inserting the link rod 9 from the rear door 619b. Regarding this connection, it is preferable that when the slider 613 is at the lower limit position of the stroke, the control lever 7a is reliably pushed down, and the mooring device 7 is adjusted so as to be in a non-latchable state. The inner diameter of the bottomed cylindrical output shaft 619 is made relatively large so as to be adaptable to link rods of various thicknesses. Similarly, the stroke of the linear reciprocating motion in the motion conversion mechanism 6 is set to be relatively larger than the swing stroke of the control levers of various mooring devices so as to be adaptable to the control levers.

The bottomed cylindrical output shaft 619 has its lower opening 6
The distal end 9a of the link rod inserted from 19b abuts on the inner bottom surface of the cylinder at the position where it has been inserted a predetermined distance, thereby preventing further entry. In other words, the bottomed cylindrical output shaft 61
The connection between the link rod 9 and the distal end portion 9a of the link rod is not fixed, but merely presses the distal end 9a of the link rod from above while resisting the force of the spring applied to the control lever 7a of the mooring device 7. Absent. Therefore, the stroke of the vertical movement of the slider 613 of the motion conversion mechanism 6 and the stroke of the vertical movement of the control lever 7a of the mooring device 7 can be set independently of each other, and there is an advantage that the degree of freedom for adapting to various mooring devices is high. There is.

As described above, if the operation proxy device according to the present invention is mounted in the rear door, the control lever 7a is lowered to the lower limit by the lower end of the link rod 9 with the power supply to the motor 4 and the slider 613 being lowered. Depressed. As a result, the mooring device 7 changes from a latchable state to a non-latchable state, and the mooring device 7 is disengaged from the vehicle body side locking portion, and the rear door can be opened. Further, in this state, when the power supply to the motor 4 is cut off, the motor 4 tends to rotate in the reverse direction by the force received from the control lever 7a of the mooring instrument 7, but the motor 4 is doubled between the control lever 7a and the motor 4. Motion conversion mechanism 6 and reduction gear 5 acting as a force mechanism
, An extremely large reverse rotation preventing force acts, whereby the slider 613 maintains the same position. In other words, the mooring device 7 can be maintained in a non-latchable state even when the power supply to the motor 4 is cut off.

Next, the case of FIG. 5 will be described. In the figure, a door-side mooring device (commonly called “catch”) 8 is attached to, for example, a lower end portion of a rear door. The mooring device 8 is provided with a locking portion receiving port 8b for receiving a mooring locking portion (not shown) on the vehicle body side, and a control lever 8a. The control lever 8a is rotatably supported in the vertical direction, and is normally urged downward by a strong spring. When the control lever 8a is at the lower end position, the mooring device 8 is set in a latchable state. When the rear door is closed in the latchable state, the vehicle-side locking portion that enters from the locking portion receiving port 8b is
The nail is locked or engaged with the claw inside the mooring device and cannot be removed.
On the other hand, when the control lever 8a is pushed up to the upper end position, the mooring device 8 is set to a non-latchable state. In a state in which the latching is not possible, the locking or engagement between the vehicle body side locking member and the claw mechanism inside the mooring device is released, and the vehicle body side locking portion can be detached from the mooring device 8, thereby opening the rear door. Becomes possible.

In a commercially available vehicle, the operation of the mooring device 8 is performed by applying a force from the operating lever for opening and closing the rear door to the wire 10.
Is transmitted to the control lever 8a of the mooring device 8 via the That is, the control lever 8a is normally urged to the lower end position by the force of the spring, whereby the
Is in a latchable state, but if the user pulls the opening / closing operation lever with his finger to open the rear door, the movement is transmitted to the wire 10 and the control lever 8a is pulled up, whereby the mooring device 8 is latched. It becomes impossible.

On the other hand, in the case of a vehicle that has been subjected to a smoothing process with respect to the rear door, the operation lever for opening and closing the rear door is not used. Therefore, the wire 10 is changed to a short wire, and as shown in FIG. 5 (b), the retaining ball 10a at the tip of the wire 10 is vertically cut integrally with the slider 613 to make an L-shaped cut in the bottomed cylindrical output shaft 619. The wire 10 is connected to the operation substitute device (motion conversion mechanism 6) mounted in the rear door by hooking and fixing the wire 619a.
Regarding this connection, it is preferable that the control lever 8a is securely pulled up when the slider 613 is at the upper limit position of the stroke, and the mooring device 8 is preferably adjusted so as to be in a non-latchable state.

As described above, when the operation proxy device according to the present invention is mounted in the rear door, the slider 613 is raised and the control lever 8a is pulled up to the upper limit by the wire 10 when the motor 4 is energized. . As a result, the mooring device 8 changes from a latchable state to a non-latchable state, and the mooring device 8 is disengaged from the vehicle body side locking portion,
The rear door can be opened. Further, in this state, when the power supply to the motor 4 is cut off, the motor 4 tends to rotate in the reverse direction due to the force received from the control lever 8a of the mooring device 8, but there is a double between the control lever 8a and the motor 4. Since the motion converting mechanism 6 and the speed reducer 5 acting as a force mechanism are interposed, an extremely large reverse rotation preventing force acts, whereby the slider 613 maintains the same position. That is, the mooring device 8 can be maintained in a state where latching is impossible even when the power supply to the motor 4 is cut off.

A switch (hereinafter referred to as an open switch) operated to change the mooring device from a latchable state to a non-latchable state to open the rear door, and a mooring device to close the rear door. FIG. 6 shows an example of a mounting position of a switch (hereinafter, referred to as a close switch) operated to change the state from a non-latchable state to a latchable state. In the drawing, reference numeral 1 denotes an operation proxy device main body, 11 denotes a rear door of a vehicle body, 12 denotes an open switch, 13 denotes a close switch, and 14 denotes an instrument panel in a driver's seat.

As shown in FIG. 6A, the open switch 12 is attached to the lower right of the instrument panel 14 on the front of the driver's seat in the vehicle, that is, to the vicinity of the driver.
Therefore, unlike the conventional example in which the rear door is not visible on the outer surface of the vehicle body, the rear door cannot be opened unless the vehicle enters the inside of the vehicle. As a result, the operation proxy device of the present invention uses the locking mechanism for the rear door. Will also function. As a structure of the open switch 12, a momentary type push button switch is adopted. As described later, the motor started by the switch 12 uses a relay using a relay until a predetermined limit switch is operated. The rotation is continued by the holding circuit.

As shown in FIG. 6 (b), the close switch 13 is located at the lower right of the inner surface of the rear door 11 in the vehicle, that is, when the rear door 11 is open.
It is installed in a position that can be operated from outside the vehicle. In addition,
As a structure of the close switch 13, similarly, a momentary type push button switch is adopted, and as described later, the motor started by the switch 13 uses a relay until a predetermined limit switch is operated. The rotation is continued by the self-holding circuit.

How to use the switches 12 and 13 is as follows. In order to stop the vehicle and open the rear door 11, the driver operates the open switch 12 at hand before the driver gets off the vehicle. Then, the self-holding circuit using the relay is set to the holding state, the energization of the motor 4 is started, and the slider 613 linearly moves in a fixed direction through the above-described process, and the link rod 9 or the wire 1 is moved.
Through 0, the control levers 7a, 8a of the mooring devices 7, 8 are operated downward or upward. When the slider 613 reaches the limit position of the predetermined stroke and the mooring devices 7, 8 are changed from the latchable state to the unlatched state,
When one of the limit switches 621 and 622 operates, a predetermined limit signal is generated. In response to this limit signal, the self-holding circuit is released from self-holding, and the power supply to the motor 4 is automatically cut off. Thereafter, the slider 613 stays at that position due to the above-described reverse rotation preventing force of the motor, whereby the mooring devices 7, 8 are held in a non-latchable state, and in this state, the rear door can be opened. Become. On the other hand, when the rear door 11 is closed, the close switch 13 attached to the inner surface of the rear door 11 is pressed from outside the vehicle prior to the closing. Then, the self-holding circuit using the relay is brought into the holding state, the energization to the motor 4 is restarted, and after the above-described process, the slider 613 performs a linear motion in the direction opposite to the previous direction, and the link rod 9 or the link rod 9 or Via the wire 10, the control levers 7a, 8a of the mooring devices 7, 8 are operated upward or downward. When the slider 613 reaches the other limit position of the predetermined stroke and the mooring devices 7 and 8 are changed from the non-latchable state to the latchable state, one of the limit switches 621 and 622, which is opposite to the previous one, is activated. Thus, a predetermined limit signal is generated. In response to this limit signal, the self-holding circuit is released from self-holding, and the power supply to the motor 4 is automatically cut off. Thereafter, the mooring devices 7 and 8 are held in a state where they can be latched by the force of the built-in spring. In this state, the rear door 11 is closed and the mooring device and the vehicle body side locking portion are irremovably coupled. Becomes possible.

In the above embodiment, the device of the present invention is applied for opening and closing the rear door. However, the device of the present invention can be arbitrarily applied to other vehicle doors (for example, vehicle side doors). Of course. Further, the mechanism for converting the rotational movement of the motor into the linear movement is not limited to the mechanism disclosed in the embodiment.
