DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a fuel cut device for shutting off fuel supply to an engine.

[0002]

2. Description of the Related Art In a diesel engine of an automobile or the like, the supply of fuel is cut off to stop the engine. As shown in FIG. 11, a fuel cut device that cuts off the supply of fuel generally has a stop lever 1 for moving a rack in an injection pump.
2 and a solenoid 20 connected to the rod link 60 via a ball joint 62.

[0003] This general fuel cut device 10
Is turned on or off by interlocking with a starter key or the like, and the solenoid 20 is operated or stopped, and the rod link 60 connected to the solenoid 20 is moved forward and backward with respect to the injection pump 64 to stop. By opening and closing the lever 12, the fuel is supplied or cut off.

[0004]

However, since the overall length of the rod link 60 is related to the delicate degree of opening and closing of the stop lever 12, it is necessary to set it accurately. For this reason, conventionally, there was a problem that setting and adjustment of the entire length of the rod link 60 was troublesome, and installation was troublesome.

[0005] As a result, even when it is necessary to change the arrangement of each part, it is necessary to readjust the entire length of the rod link 60 or replace it with another rod link 60 having a different length. There is a problem that the operation is very troublesome and the cost is high. For this reason, component placement changes
Usually, it is often performed on the premise that the total length of the rod link 60 is not changed. In this case, since the rod link 60 has a fixed length that has been set, the arrangement of parts is restricted by the total length of the rod link 60. As a result, there is a problem that the degree of freedom in designing the layout of each part is reduced. These problems also occur when the fuel cut device 10 is mounted on a plurality of different types of vehicles.

Further, since the rod link 60 requires the use of a ball joint 62 as shown in FIG. 11 to connect with the solenoid 20, the weight of the fuel cut device 10 is increased, The stop lever 12 itself of the injection pump 64 needs to have rigidity to support the mass of the rod link 60, the ball joint 62, and the like. For this reason, there is still room for improvement in terms of weight reduction required for automobiles in general.

Therefore, it is conceivable to reduce the weight by using a wire instead of the rod link 60. However, even if a wire is used, unless the entire length is set accurately and adjusted, the wire is slackened between the solenoid 20 and the stop lever 12, and the delicate opening and closing of the stop lever 12 cannot be accurately controlled. There is a risk. Also, for this reason, if it is necessary to change the length or stroke of the wire due to a change in the layout of parts, it is necessary to readjust the entire length of the wire,
The setting and adjustment are still troublesome,
As a result, there is a problem in that the degree of freedom in the component layout design is restricted by the entire length of the wire, and is reduced.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems by freely holding the wire in a tensioned state without finely adjusting or changing the entire length of the wire, thereby enabling freedom in designing and designing parts. It is an object of the present invention to provide a fuel cut device which can increase the degree and reduce the weight as a whole.

[0009]

According to the present invention, as a first means for solving the above-mentioned problems, a wire having one end connected to a stop lever and a wire connected to the other end of the wire to stop the wire are provided. There is provided a fuel cut device provided with wire advance / retreat means for moving forward / backward with respect to a lever, further comprising a wire tensioning means for holding a wire in a tensioned state.

As described above, when the wire tensioning means is provided and the wire is always kept in a tensioned state, it is possible to prevent the wire from being loosened without finely adjusting the entire length of the wire. Can be opened and closed. For this reason, even if there is a slight change in the layout of the components, the length of the wires is not significantly restricted, and the degree of freedom in designing the layout is increased.

According to the present invention, as a second means for solving the above-mentioned problems, in the first means for solving the problems, the wire tensioning means is connected to a wire holder for holding the other end of the wire and the wire holder. Further, the present invention provides a fuel cut device comprising an adjusting screw which is screwed into the movable portion of the wire advancing / retreating means and which advances and retreats by varying the amount of screwing into the movable portion.

As described above, when the wire tensioning means is composed of the wire holder and the adjusting screw, the slack of the wire can be prevented only by moving the adjusting screw forward and backward with respect to the movable portion of the wire advancing / retreating means. Therefore, the tension of the wire can be adjusted very easily, and it is not necessary to use a ball joint, so that the weight can be reduced.

According to the present invention, as a third means for solving the above-mentioned problems, in the first means for solving the problems, the wire advance / retreat means comprises an oscillating wire holder for holding the other end of the wire; A drive source for driving the oscillating wire holder to oscillate, and the wire tensioning means comprises an urging member for urging the oscillating wire holder in the tensioning direction of the wire. And a fuel cut device.

As described above, when the swinging wire holder is moved forward and backward by the swinging movement of the swinging wire holder, and the swinging wire holder is constantly urged in the tension direction of the wire by a biasing member such as a coil spring, the swinging wire holder becomes The held wire is always pulled in the direction opposite to the traveling direction and does not loosen, and the wire is automatically held in tension regardless of the length of the wire. Since it is not necessary to adjust the state at all, the slack of the wire can be absorbed very easily without being restricted by the length of the wire. In addition, for this reason, even when the positional relationship between the stop lever and the drive source is changed due to the change in the arrangement of the parts, it is possible to cope without any adjustment of the total length and the tension state of the wire. This increases the degree of freedom in designing parts layout. Furthermore, when using a swinging wire holder,
Since the degree of freedom of the wire take-out angle is increased, the degree of freedom in designing the layout of components is further improved.

According to a fourth aspect of the present invention, in the first aspect, the wire moving means includes a wire holder for holding the other end of the wire, and a wire holder. The fuel cut device comprises a driving source for driving, and the wire tensioning means comprises a variable connecting portion capable of changing a connecting position of the wire or the driving source to the swingable wire holder. .

As described above, if the connection position of the wire or the drive source to the swinging wire holder can be changed, the wire can be held in a tensioned state without adjusting the entire length of the wire, and at the same time, the tension can be maintained. The state can be easily adjusted.

By combining the third and fourth means for solving the above problems, the wire is automatically held in a tensioned state by a biasing member such as a winding spring, and at the same time, the tension is adjusted by a variable connecting portion such as a daruma hole. If the state can be adjusted, it is possible to take a large adjustment allowance for the tension state of the wire, it is possible to freely change the pulling force and stroke of the wire according to the plan, and the degree of freedom in designing the layout of parts is increased. Can be further enhanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a fuel cut device 10 of the present invention. And a wire moving means 16 connected to the wire 14 for moving the wire 14 forward and backward with respect to the stop lever 12.
And wire tensioning means 18 for holding the wire 14 in a tensioned state.

In the illustrated embodiment, the wire reciprocating means 16 comprises a solenoid 20, which, as shown in FIG. 1, has a movable part in the form of an armature which is movable to reciprocate the wire 14. The movable part 22 includes a movable rod 24 attracted by a solenoid coil (not shown) and a bracket 26 attached to the movable rod 24. The solenoid 20 excites or demagnetizes the solenoid coil by energizing or de-energizing in conjunction with a starter key or the like, and causes the movable portion 22 as an armature to move forward and backward with respect to the stop lever 12.

The wire 14 is, as shown in FIG.
Attached to the movable rod 24 via this bracket 26, and the movable rod 24 of the solenoid 20 advances and retreats.
Stop lever 1 moves back and forth with respect to stop lever 12
Open and close 2. The stop lever 12 is provided to move a rack in an injection pump (not shown). Usually, as shown in FIG.
It is urged by an appropriate urging means so as to incline toward the side (clockwise in FIG. 1) to supply the fuel (see the solid line position of the stop lever 12 in FIG. 1). By tilting the solenoid 20 in the opposite direction (counterclockwise direction in FIG. 1) (see the position indicated by the dotted line of the stop lever 12 in FIG. 1), the fuel supply is shut off.

Therefore, in the illustrated embodiment, the wire 1
4 is pulled by the solenoid 20 and retracted with respect to the stop lever 12 so that the stop lever 12
Is tilted in the opposite direction (counterclockwise) from the solenoid 20 to shut off the fuel supply, but when released from this state,
The wire 14 is pulled toward the stop lever 12 by the urging means of the stop lever 12 and moves forward, so that the fuel is supplied. Therefore, this wire 1
4 is a movable part 2 of the stop lever 12 and the solenoid 20
If the movable portion 22 of the solenoid 20 moves forward and backward, the stop lever 12 cannot be opened and closed properly in response to the advance and retreat of the movable portion 22 of the solenoid 20, so that the wire 14 needs to be kept in a tensioned state.

In the embodiment shown in FIGS. 1 and 2, the wire tensioning means 18 comprises a wire holder 28 for holding the other end of the wire 14 on the side opposite to the stop lever 12, and an adjusting screw connected to the wire holder 28. 30. As shown in FIG. 1, the adjusting screw 30 is screwed into the bracket 26 of the movable portion 22 of the solenoid 20, which is the wire advancing / retreating means 16, and advances and retreats with respect to the movable portion 22 by varying the amount of screwing. Is done.

More specifically, the adjusting screw 3
2 is screwed into a nut 32 fixedly mounted on the bracket 26 on the opposite side through a screw through hole 26A formed in the bracket 26 as shown in FIG. Wire 14
Is connected to the movable portion 22 of the solenoid 20 and at the same time, the amount of screwing of the screw is appropriately changed and adjusted, so that the wire 14 connected to the adjusting screw 30 via the wire holder 28 is always kept in a tensioned state. be able to. Therefore, the wire 14 can be brought into a tensioned state by the screwing amount of the adjusting screw 30 without finely adjusting the entire length of the wire 14.

For this reason, when the fuel cut device 10 is first assembled, or when the size of the fuel cut device 10 slightly shifts due to a change in air temperature during use, the adjusting screw 30 is not required.
Only by moving the adjusting screw 30 forward and backward with respect to the bracket 26 as the movable portion 22 by adjusting the screwing amount of the wire 1
It is possible to very easily prevent the wire 14 from becoming slack and to surely open and close the stop lever 12 as necessary, without the troublesome work of finely adjusting and re-adjusting the entire length of the wire 4. Of course, in particular, even when it is necessary to make a slight change in the arrangement relationship between the solenoid 20 and the stop lever 12 due to a change in arrangement or the like, the wire 14 is not significantly restricted by the entire length of the wire 14. Since it can be easily handled, the degree of freedom in designing parts layout is increased.

The use state of the fuel cut device 10 according to the embodiment shown in FIGS. 1 and 2 will be briefly described.
When the distance between the stop lever 12 and the solenoid 20 is short and the wire 14 is loose, the operator turns the adjusting screw 30 to advance the adjusting screw 30 with respect to the bracket 26 (to move the adjusting screw 30 rightward in the drawing). ), A moderate tension can be applied to the wire 14. Conversely, when the tension of the wire 14 becomes excessive, the adjusting screw 30 is retracted with respect to the bracket 26 (to the left in the drawing). By moving the wire 14), the wire 14 can be brought into a moderate tension state. As described above, the adjusting screw 30 has a function of not only holding the wire 14 in a tensioned state but also appropriately adjusting the tensioned state.

In this case, the amount of advance and retreat of the adjusting screw 30 with respect to the bracket 26 is determined by the screw portion 30A of the adjusting screw 30.
Is determined by the length L (see FIG. 2),
The length L of 0A (see FIG. 2) is appropriately set within a necessary range. In the illustrated embodiment, the adjustment screw 30
Was screwed to the bracket 26 with the nut 32,
The adjusting screw 3 is provided in the screw through hole 26A of the bracket 26 itself.
0 is provided with a screw to be screwed into the screw portion 30A, and the adjusting screw 3
0 may be screwed together, and in this case, the nut 32 may be further omitted or used together. Thereby, the wire 14 and the solenoid 20 can be connected with sufficient strength.

In the illustrated embodiment, the nut 32
Is fixed to the bracket 26 and the adjusting screw 30 is turned. However, the present invention is not limited to this. The nut 32 is used separately from the bracket 26 and the nut 32 is turned. By turning both the adjusting screw 30 and the adjusting screw 30, the wire 14 may be kept in tension.

In the illustrated embodiment, the adjusting screw 3
In order to prevent the wire 14 from being twisted at the time of adjusting the screw-in amount, the head 30B of the adjusting screw 30 is rotatably connected to the wire holder 28, as shown in FIG. Thus, the wire 14 and the wire holder 28,
When the adjusting screw 30 is used, the wire 14 can be held in a tensioned state without adjusting the entire length of the wire 14 with a very simple configuration, and it is not necessary to use a ball joint. It is also possible to reduce the weight as compared with.

Next, the fuel cut device 10 of the present invention will be described.
Another embodiment will be described with reference to FIGS. 3 to 8. In the embodiment shown in FIGS. 3 to 8, the wire advance / retreat means 16 includes an oscillating wire holder 34 for holding the wire 14 and And a drive source 36 for driving the oscillating wire holder 34 to oscillate. The wire tensioning means 18 includes an urging member 38 for urging the oscillating wire holder 34 in the tensioning direction of the wire 14. It has.

In the embodiment shown in FIG. 3, the oscillating wire holder 34 comprises a disk 34A.
Is swingably supported by a support shaft 40 fixedly attached to a frame (not shown). The wire 14 is shown in FIG.
As shown in the figure, the end of the opposite side to the stop lever 12 side is located at a position deviated from the center axis of the disk 34A.
When the disk 34A swings about the support shaft 40, the wire 14 moves forward and backward, and the stop lever 12 swings.

The urging member 38 is, in the illustrated embodiment,
As shown in FIGS. 3 (B) and 5, it is composed of a winding spring 46 wound around a body 35A fixed to the support shaft 40 close to the disk 34A. One end of the coil spring 46 is fixed to a disk 35B fixed to the support shaft 40 by approaching the body 35A on the side opposite to the disk 34A.
The other end of the disk 6A is supported by a support shaft so as to swing freely.
It is fixed to. Accordingly, the helical spring 46 is allowed to swing by the restoring force of returning to the linear state.
A is urged to swing in the counterclockwise direction in FIG. 3 (see the arrow A in FIG. 3).

For this reason, the wire 14 is
Due to the swinging of the disc 34A in the counterclockwise direction by the urging force of No. 6, the wire 14 is always kept in tension regardless of the entire length of the wire 14. In this case, in particular, since the disk 34A is constantly urged in the tensioning direction of the wire 14, the wire 14 is automatically held in a tensioned state. Unlike the embodiment of FIGS. 1 and 2 in which the amount is adjusted, the slack of the wire 14 can be prevented very easily without the operator adjusting the tension of the wire 14 at all, which is advantageous. . As a result, the stop lever 12 and the solenoid 2
The wire 14 is also used when the positional relationship with the
Can be adjusted without fine-tuning or re-adjusting the overall length and tension of the vehicle.

In the illustrated embodiment, the drive source 36 is shown as a solenoid 20, as shown in FIG. 3, as in the embodiment shown in FIGS. As shown in FIG. 3A, the movable rod 24 of the solenoid 20 is connected to a position off the center axis of the disk 34A of the swingable wire holder 34. In this case, as shown in FIG. 4, the movable rod 24 of the solenoid 20 has a connecting pin 42 extending in a direction perpendicular to the axial direction of the movable rod 24, and the connecting pin 42 is formed in a vertically long shape formed on the disk 34A. It is engaged with the clevis 44 and is connected to a disk 34A which is a swingable wire holder 34.

For this reason, the movable rod 2 of the solenoid 20
When 4 moves linearly with respect to the stop lever 12,
The linear movement of the movable rod 24 is converted into the swinging movement of the swingable wire holder 34 by the connecting pin 42 and the clevis 44, and as shown by arrows A and B in FIG.
The swing type wire holder 34 swings. The swing stroke of the swing type wire holder 34 is the clevis 44.
Is regulated by the length S (see FIG. 4), the length S (see FIG. 4) of the clevis 44 is appropriately set within a necessary range.

The operating state of the fuel cut device 10 according to the embodiment shown in FIG. 3 will be described. In the fuel supply state, the movable rod 24 of the solenoid 20 is extended as shown in FIG. Thus, the stop lever 12 is allowed to incline toward the solenoid 20 by the urging means (see the solid line position of the stop lever 12 in FIG. 3). In this state, the coil spring 46 urges the disc 34A in the wire tensioning direction (the direction of the arrow A in FIGS. 3 and 4) against the urging force of the stop lever 12, so that the wire 14 Are kept in tension.

In this case, by setting the urging force for urging the disc 34A by the winding spring 46 to be smaller than the urging force of the stop lever 12, the disc 34A is brought into a state where the wire 14 is in a tension state. And more wire 14
Cannot be swung so as to pull, and the movement of the clevis 44 stops in the intermediate state shown in FIG. 4A with respect to the connecting pin 42 of the movable rod 24. For this reason,
The swing of the disc 34A in the tensioning direction of the wire 14 is automatically restricted, and when the fuel supply is necessary, it is possible to prevent the wire 14 from being pulled more than necessary and the stop lever 12 from being in the fuel supply cutoff state. Can be.

Next, the stop lever 12 is moved from this state.
When the fuel supply is cut off, the solenoid 20 is excited, and the movable rod 24 is moved to the stop lever 12.
4A, the connecting pin 42 is moved backward from the state shown in FIG.
As shown in (B), the stop lever 12 of the wire 14
The disk 34A is swung in the direction of arrow A in FIG. 3 while engaging the end portion 44a of the clevis 44 in the direction opposite to the traveling direction of the clevis 44 and winding and loosening the winding spring 46. As a result, the wire 14 is pulled, and the stop lever 12 is pulled.
In the fuel supply cutoff state. In this case, the wire 14
Since the wire 14 is held in a tensioned state without slack by the winding spring 46 at the start of the swing, the wire 14 is designed to reliably bring the stop lever 12 into the fuel supply cutoff state simultaneously with the start of the swing of the disk 34A. Can be rocked. Note that the wire 14 is pulled in the tensioning direction even during the swinging of the disc 34A in the counterclockwise direction in FIG. 3 (see the arrow A in FIG. 3), so that the wire 14 is kept in a tensioned state. It is.

Thereafter, when the solenoid 20 is demagnetized, the wire 14 is pulled leftward in FIG. 3 by the urging means (not shown) of the stop lever 12, so that the connecting pin 42 of the movable rod 24 changes the position of the clevis 44 again. 4 (A), the disk 34A swings in the direction of arrow B in FIG. 3 and returns to the original position. Thereby, the wire 14 is kept in a tensioned state by the urging force of the winding spring 46,
Advances with respect to the stop lever 12, the stop lever 1
2 is in the open position, so that the fuel is supplied again.

In the above embodiment, the coil spring 4
6, the urging force of the disc 34A is set smaller than the urging force of the stop lever 12, thereby restricting the disc 34A from swinging more than necessary in the tensioning direction of the wire 14 in the fuel supply state. As shown in FIG. 4C, the connecting pin 42 provided on the movable rod 24 is engaged with the end 44 a of the clevis 44 on the stop lever 12 side, so that the wire 14 It is also possible to restrict unnecessarily swinging in the direction of tension. In this case, the length S (see FIG. 4) of the clevis 44 for determining the restriction position is appropriately set. In addition,
Of course, the extension force of the movable rod 24 of the solenoid 20 is set to be greater than the urging force of the coil spring 46 so that the movable rod 24 of the solenoid 20 does not contract due to the urging force of the coil spring 46. In addition, the solenoid 2
The force for retracting the zero wire 14 is the stop lever 12
It is needless to say that it is necessary to make the urging force larger than the urging force for urging the fuel supply state.

As shown in FIG. 6, the wire tensioning means 18 is a wire 14 or a solenoid 2 which is a driving source 36.
Further, there is further provided a variable connecting portion 48 which can change a connecting position to the swingable wire holder 34 of No. 0. This variable connecting part 48
In the embodiment shown in FIG. 6, the oscillating wire holder 3
The wire 14 is provided in the disk 34A of No. 4 and formed by connecting the two holes 50A and 50B to each other. The wire 14 is connected to one of the two holes 50A and 50B.

Thus, the connection position of the wire 14 can be changed to one of the two holes 50A and 50B according to the distance between the stop lever 12 and the solenoid 20. The tension of the wire 14 can be adjusted by changing the connection position of the wire 14 to the oscillating wire holder 34.
In addition, the adjustment allowance for adjusting the tension of the wire 14 can be further increased. In addition, this wire 14
By changing the connection position of the wire 14 to the oscillating wire holder 34, the pulling force and the stroke of the wire 14 can be freely changed in accordance with the plan without changing the stroke of the solenoid 20. Therefore, the degree of freedom in designing the layout of parts is further increased.

As shown in FIG. 6, the wire 14 can be connected to the daruma hole 50 by a fastener 52. The fastener 52 includes, for example, a flanged nut 52A around which the wire 14 is wound and attached, and a flanged nut 52A.
A, and a flanged screw 52B screwed into A.
At the time of connection, as shown in FIG.
Engages with one of the holes 50A and 50B, and when the connection position is variable, as shown in FIGS.
2B is loosened, and the screw portion 52a is inserted into the two holes 5
0A and 50B are moved along a communicating portion 50C that communicates with the nut 52A again at a predetermined hole 50A or height 50B.
To connect the wire 14 to the disk 34A.

However, the wire 14 is connected to the oscillating wire holder 3
The means for connecting to 4 is not necessarily limited to this, but may be performed by other appropriate means, for example, by directly connecting the wire 14 to one of the holes 50A and 50B of the daruma hole 50. . In addition, the variable connecting portion 48
Is not necessarily limited to the darma hole 50, and may be constituted by other appropriate means, for example, a plurality of holes independently formed as long as the connection position of the wire 14 can be changed. May be. Furthermore, the variable connection part 4
The variable position set by 8 is 2 as shown in FIG.
It is not limited to the three holes 50A and 50B, and it is also possible to secure a larger allowance for adjusting the tension of the wire 14 as three or more appropriate variable positions.

In the variable connecting portion 48 shown in FIG. 6, the connecting position of the wire 14 is changed. However, as shown in FIG.
In order to connect the movable rod 24 of the solenoid 20, two clevises 44 </ b> A and 44 </ b> B may be provided on the swinging wire holder 34 to change the connection position of the movable part 22 of the solenoid 20. In these cases, one or both of the wire 14 and the movable portion 22 of the solenoid 20 can be connected.

By using the oscillating wire holder 34, the degree of freedom of the take-out angle of the wire 14 is increased as shown in FIG. 8, so that the arrangement of parts can be freely set. In this case, as shown in FIG. 9, for example, the wire 14 can be bent and wired, and the degree of freedom in arranging components can be further increased.

In the embodiment shown in FIGS. 3 to 8, the wire tensioning means 18 is configured by combining the biasing member 38 such as a winding spring 46 and the variable connecting portion 48 such as a daruma hole 50. However, these may be used alone. For example, only the urging member 38 such as the winding spring 46 may be used, and the variable connecting portion 48 may be omitted. Even in this case, the wire 14 can be held in a tensioned state by the winding spring 46.

On the other hand, the biasing member 38 such as the winding spring 46 may be omitted by using only the variable connecting portion 48 such as the daruma hole 50. Also in this case, the position of the wire 14 or the drive source 36 connected to the disk 34A can be changed by the variable connection portion 48, so that the wire 14 is maintained in a tensioned state without adjusting the entire length of the wire 14. At the same time, the tension can be easily adjusted.
In this case, the swing of the disk 34A is forcibly restricted by using a motor or the like described later as the drive source 36.

Further, as shown in FIG. 10, the variable connection portion 48 is provided with a darma hole 50 in the wire holder 54 attached to the movable rod 24 of the drive source such as the solenoid 20, as shown in FIG. It can also be provided by forming.

Also, in the illustrated embodiment,
Although the wire advance / retreat means 16 is made of the solenoid 20, it is not limited to this. In particular, in the embodiment of the swing type wire holder 34 shown in FIGS. Appropriate means such as a motor connected to the center of the moving wire holder 34 can also be used.
In this case, the motor itself can function as a means for tensioning the wire 14. Further, the swingable wire holder 34 may be a lever arm type other than the disk 34A.

In the illustrated embodiment, the support shaft 4
0, the body 35A and the disk 34B are fixed, and only the disk 34A, which is the oscillating wire holder 34, is swingable.
Disk 34A and disk 35B holding both ends of the helical spring 46
If the disk 35B is fixed, the winding spring 46
The disc 34A can swing relatively to the disc 35B by the urging force of the support shaft 40 and the body 35A.
Is fixedly connected to the disk 34A, and the support shaft 40 is rotated together with the disk 34A or the body 3
5A may be rocked. In addition, the torso 35A is
When swingable together with A, the wire 14 can be wound around and held by the body 35A.

[0051]

According to the present invention, as described above, since the wire is always kept in the tensioned state by the wire tensioning means, it is possible to prevent the wire from becoming loose without finely adjusting the entire length of the wire. The stop lever can be opened and closed reliably, and therefore, even if there is a slight change in the routing of the component, it is not significantly restrained by the entire length of the wire. There is a growing benefit.

According to the present invention, as described above, the wire holder and the adjusting screw are used as the wire tensioning means. Since the slack can be prevented, the tension of the wire can be adjusted very easily, and there is no need to use a ball joint, so that there is a real advantage that the weight can be reduced.

According to the present invention, as described above, the wire is moved forward and backward by the swing of the swinging wire holder, and the swinging wire holder is always biased in the tension direction of the wire by a biasing member such as a winding spring. As a result, the wire held by the swinging wire holder is always pulled in the direction opposite to the traveling direction and does not loosen, and is automatically held in tension regardless of its entire length. There is no need to finely adjust the tension of the wire, and therefore, there is a benefit that the slack of the wire can be absorbed very easily without being restricted by the entire length of the wire.

[0054] For this reason, with the change of the part arrangement,
Even if there is a change in the positional relationship between the stop lever and the drive source, etc., it is possible to respond without adjusting the overall length or tension of the wire at all, thus increasing the degree of freedom in component layout design. There is. Further, the use of the oscillating wire holder increases the degree of freedom of the wire take-out angle, thereby further improving the degree of freedom in designing the layout of components.

According to the present invention, as described above, since the connection position of the wire or the drive source to the oscillating wire holder can be changed, the wire is held in a tensioned state without adjusting the entire length of the wire. At the same time, there is a real benefit that the tension can be easily adjusted.

Further, according to the present invention, as described above, the wire can be automatically held in a tensioned state by the biasing member such as a winding spring, and at the same time, the tension can be adjusted by a variable connecting portion such as a daruma hole. Because, it is possible to take a large adjustment allowance for the tension state of the wire, it is possible to freely change the pulling force and stroke of the wire according to the plan,
There is a real benefit that the degree of freedom in policy design can be further increased.
