Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a door window regulator for guiding the door glass of an automobile up and down.

[Background Art] Generally, a door window regulator has an X-shaped arm made of a steel plate, and the door glass attached to the upper end of the X-shaped arm is moved up and down by the rotation of the X-shaped arm. It is becoming. However, the door window regulator using this X-shaped arm is relatively heavy and has a wide movement trajectory, which causes restrictions on the shape and structure of the door.

For this reason, door window regulators have heretofore been proposed mainly for the purpose of reducing weight by using wires as glass driving means.

As an example, US Pat. No. 4,109,417 discloses a structure in which a wire is wound around pulleys that are pivotally supported at the upper and lower parts of the guide, and a lifting force is applied to the window glass. However, in this window regulator, the wire between the pulleys is straight, and when the window glass is raised to the highest level, this wire is located closer to the interior than the guide, making it necessary to increase the thickness of the door. For this reason, it is difficult to provide a recess on the inside of the door to increase the interior space or to give a three-dimensional shape to the door trim, which is the interior lining of the door.

In particular, recently, the radius of curvature of glass has become smaller in order to increase the space inside the vehicle, and the radius of curvature of the guide has also become smaller, resulting in a larger amount of wire protruding into the vehicle interior than the guide. Become.

Furthermore, German Published Patent Application No. 3108557 shows a wind regulator having a similar structure, in which the guide has a shape that swells toward the outside of the vehicle interior. However, with this structure, the angle at which the wire is wrapped around the pulley changes depending on whether the window glass is up or down, and force in the thrust direction is applied to the pulley, causing an increase in frictional resistance.

In Japanese Unexamined Patent Publication No. 55-161173 and Japanese Utility Model Application No. 55-41996, a wire is disposed within a guide so that the wire can be moved within the guide. However, this increases the width of the guide and complicates the structure of the slider. Also, the frictional resistance is large,
It can also cause rust.

[Purpose of the invention] Taking the above facts into consideration, the purpose of the present invention is to obtain a door window regulator that can expand the interior space of a vehicle even when the driving force is transmitted through wires, and also has a small frictional force applied to the wires. be.

[Summary of the invention] The door window regulator according to the invention has the following features:
A guide member attached to the door, a slider that moves guided by this guide member and is attached to the lower part of the window glass, a pulley that is pivotally supported at the upper and lower parts of the guide member, and a slider that moves between the upper and lower pulleys of the guide member. A wire that is stretched across and connected to the lower part of the window glass between the upper and lower pulleys to form a closed loop, a drive section that drives a part of this closed loop wire, and a wire that protrudes from the guide member and comes into contact with the wire between the upper and lower pulleys. A wire guide shoe that restricts movement of the wire toward the interior of the vehicle;
As the drive unit rotates, the wire between the upper and lower pulleys applies lifting force to the window glass, and the wire between the pulleys is displaced to the outside of the vehicle interior by the wire guide shoe, so the interior space of the vehicle is improved. It is possible to increase the frictional resistance of the wire, and the frictional resistance of the wire is also becoming smaller.

[Embodiment of the invention] FIG. 1 shows a window regulator 12 housed in a door 10 and a window glass 14 raised and lowered by the regulator.

The wind regulator 12 is configured such that a front guide member 16 and a rear guide member 18, which are arranged apart from each other in the longitudinal direction of the vehicle, guide the window glass 14 up and down. In addition, the front guide member 16, the rear guide member 18, and the door handle 1 on the outside of these and in front of the vehicle.
A wire 22 that is stretched around a drive unit 20 that is placed at a suitable position for operating the windshield 53 applies a lifting force to the window glass 14.
Front guide member 16 and rear guide member 18
The intermediate portion is given a curvature that projects more toward the outside of the vehicle interior than the upper and lower portions (see FIG. 22), and has a curvature approximately similar to that of the window glass 14. The wire 22 is formed by twisting a plurality of thin steel wires.

As shown in FIGS. 2 and 3, a front guide upper bracket 24 is welded to the upper end of the front guide member 16, and a front upper pulley 28 is pivotally supported by a shaft 26. This shaft 26 has a stepped shape, and even if the tip end 26A is firmly caulked to the front atsuppa pulley 28, it can smoothly guide the front atspa pulley 28 without pressing the front atspa pulley 28 in the axial direction. ing.

As shown in FIG. 3, a female thread 30 is formed in the front guide upper bracket 24.
An assembly bolt 32 is screwed together from the indoor side. This assembly bolt 32 has a flange 32A in the middle part, and a minus groove 34 is formed in the head which is the end part on the indoor side.

Therefore, when assembling the front guide member 16 to the door 10, the head of the assembly bolt 32 screwed into the female thread 30 of the front guide attachment bracket 24 is inserted into the attachment hole formed in the inner plate 10A of the door 10. 3
If the nuts 38 are screwed together from the indoor side after passing through the front guide member 6, the front guide member 16 will be securely attached to the inner plate 10A, and the upper end of the front guide member 16 will be attached to the door 10.

In this case, before firmly tightening the nut 38, by applying a tool such as a screwdriver to the minus groove 34 and adjusting the rotation, the mounting position of the front guide member 16 in the vehicle width direction can be finely adjusted.

Front guide member 16 as shown in FIG.
Front guide lower bracket 40 is installed at the lower end of the
is welded. As shown in FIGS. 4 and 5, a front lower pulley 42 is pivotally supported on the front guide lower bracket 40 by the shaft 26 in the same way as the upper end of the front guide member 16, and the front guide member 16 and the door inner plate 10A are substantially connected to each other. is located between.

An assembly bolt 44 is welded to a part of the front guide lower bracket 40, as shown in FIG. It has become fixed.

As shown in FIG. 5, the front guide lower bracket 40 connects the wire 22 leading to the drive section 20.
Since the longitudinal axis of the shaft 26 is arranged to be inclined with respect to the longitudinal direction of the vehicle (arrows FR and RE directions) as shown by the arrow P, the axis of the shaft 26 is arranged perpendicularly to this longitudinal axis. As a result, the wire 22 wound around the front lower pulley 42 does not generate a large frictional force with the V-groove side surface of the pulley 42, allowing smooth movement. Further, the front guide lower bracket 40 has a notch 40A cut away on the inside of the vehicle to avoid interference with the inner plate 10A. Since the front guide lower bracket 40 is arranged at an angle, this notch portion 40A only requires a small amount of cutout, and if the front guide lower bracket 40 is not arranged at an angle, most of the front guide lower bracket 40 is cut out. This will cause the support strength of the front lower pulley 42 to decrease.

Further, this front lower pulley 42 is arranged further rearward of the vehicle than the front guide member 16, and the wire 22 leading from this pulley 42 to the drive section 20 is arranged to intersect with the front guide member 16. With this arrangement, the vertical length of the front guide member 16 can be increased, and as will be explained later, the support of the window glass 14 can be ensured.

On the other hand, the rear guide member 18 is arranged parallel to the front guide member 16 at the rear of the vehicle than the front guide member 16, as shown in FIG. A rear guide upper bracket 46 and a rear guide lower bracket 48 are also welded to this rear guide member 18, as shown in FIGS. 7 to 9.
Front guide members 16 are attached to these brackets.
As in the case of , the rear upper pulley 50 and rear lower pulley 52 are pivotally supported by the shaft 26,
A wire 22 is stretched between these.

Further, the rear guide lower bracket 46 is a combination of an assembly bolt 32 and a nut 38, and as shown in FIG. It's summery.

The wire 22 is connected to the drive unit 20 as shown in FIG.
From rear attupa pulley 50, rear lower pulley 5
2. It forms a closed loop that is wound around the front atsuppa pulley 28 and front lower pulley 42 and then returned to the drive unit 20 after being reversed.
It is connected to the window glass 14 between the rear upper pulley 50 and the rear lower pulley 52.

This coupling structure and the structure for attaching the window glass 14 to the front guide member 16 and the rear guide member 18 will be explained.

As shown in FIG. 10, a windshield bracket 54 is fixed to the lower end of the window glass 14. As shown in FIG. This windshield bracket 54
is manufactured from a steel plate, has a bent portion 54A around its periphery, and is fixed to the window glass 14 with a pair of screws 56. As shown in Figure 3, this screw 56
A circular hole 58 is formed in the window glass 14 at the mounting portion of the window glass 14, and after a synthetic resin filler 60 is brought into contact with both sides of the window glass 14, a screw 56 is screwed into a nut 62 which is brought into contact with the outside surface of the vehicle. ing.

An arm 64 projects from the vehicle front end of the windshield bracket 54, and a front slider 66 is fixed to the tip. The front slider 66 is inserted into the front guide member 16 and is in contact with the inner peripheral surface of the front guide member 16, as shown in FIG. That is, the axis of the front slider 66 is aligned with the front guide member 16.
The front guide member 16 has a substantially cylindrical shape arranged in the longitudinal direction, and the front guide member 16 is bent into a U-shape in cross section and has an opening toward the rear of the vehicle. Therefore, the front slider 66 is restricted from moving in the outdoor direction (arrow OUT direction) and indoor direction (IN direction), and is prevented from moving in the vehicle width direction, and is prevented from moving in the vehicle width direction. It is now possible to move in the RE direction. Note that the front slider 66 is preferably formed into a barrel shape in which the axial center portion has a larger outer diameter than both ends so that the front slider 66 can move smoothly within the front guide member 16.

A raised portion 54B is formed in the center of the windshield bracket 54 and projects toward the interior of the vehicle. A circular hole 68 is bored in this raised portion 54B as shown in FIG.
A nut 70 is welded to the outdoor side corresponding to the above, and a bolt 72 is screwed from the indoor side. This bolt 72 is connected to a long hole 74 formed in the raised portion 54B.
It is also used for attaching the front hook holder 76, and at the time of assembly, it is pre-assembled temporarily up to the state 72' shown in the imaginary line in FIG.

This front hook holder 76 is the 12th and 13th
As shown in the figure, it is formed by punching out a steel plate, and has a stepped bent portion 76A around its periphery. A long hole 78 is formed in the center of the front hook holder 76, and is used for tightening the bolt 72 of the windshield bracket 54 through the hole 78, as shown in FIG. Further, a circular hole 80 is communicated with one end of this elongated hole 78, and a bolt 72 temporarily assembled in advance to the windshield bracket 54 is connected to the circular hole 80.
The head of the can be penetrated.

Further, a protrusion 82 bent at a right angle is formed at one end of the front hook holder 76, and a protrusion 82 is formed at one end of the front hook holder 76.
It can be inserted into the elongated hole 74 of. Therefore, in the front hook holder 76, the protrusion 82 is connected to the elongated hole 7.
4, the bolt 72 restricts the relative movement of the elongated hole 78 in the direction perpendicular to the longitudinal direction of the elongated hole 74 in the windshield bracket 54.
Bolt 7 after the relative longitudinal position of
2, it is firmly attached to the windshield bracket 54.

As shown in FIGS. 14 and 15, wave-like irregularities 84 and 86 are formed on the abutment surfaces of the front hook holder 76 and the windshield bracket 54, respectively, to further ensure the connection between the two. This wavy unevenness 86 extends around the circular hole 68 of the raised portion 54B of the windshield bracket 54, and the wavy unevenness 84 extends around the elongated hole 78 of the front hook holder 76.
are formed around each.

A wire attachment part 88 protruding from a part of the front hook holder 76 has a box shape with one end open.
As shown in FIG. 12, a wire passage notch 92 is formed so that a wire hook 90, which is crimped and fixed in a substantially rectangular column shape, can be inserted into a portion of the wire 22.

In order to fix the wire hook 90 housed in the wire attachment part 88, a protruding piece 94 (Fig. 16) protruding from a part of the wire attachment part 88 is inserted into the wire attachment part 88, as shown in FIGS. 16 and 17. It is bent to form 94' and a wire hook 90 is held between it and the wire attachment part 88.

A synthetic resin coating 96 is applied to the wire attachment portion 88 and the protruding piece 94, thereby preventing abnormal noises generated between the wire attachment portion 88 and the protruding piece 94. That is, in FIG. 17, both axial ends of the wire hook 90 and the wire attachment portion 8
8, there may be a slight gap between the wire hook 90 and the wire hook 90, which receives this driving force, when the wire 22 is driven and moves in the longitudinal direction. Although the wire attachment part 88 moves slightly by the above-mentioned gap amount,
The synthetic resin coating 96 can absorb the abnormal noise generated by collision with the inner surface of the holder.

Conversely, there is a possibility that the wire attachment portion 88 is slightly smaller than both axial ends of the wire hook 90, and even in this case, the synthetic resin coating 96 bends to allow insertion.

As shown in FIG. 10, a cushion rubber 98 is attached to the bent portion 54A of the windshield bracket 54, and when the windshield bracket 54 is lowered to its lowest position, it comes into contact with the lower surface of the inner plate 10A of the door 10 and closes the windshield. A stopper is formed to restrict the lowering position of 14.

In this way, the windshield bracket 54
connects the windshield 14 to the front guide member 16
The wire 22 is supported and guided in the vertical direction of the vehicle, and the wire 22 between the front upper pulley 28 and the front lower pulley 42 is connected to the windshield 14 via the front hook holder 76.
The driving force of 2 is transmitted to the window glass 14.

The rear guide member 18 and the window glass 14 are connected through a rear glass bracket 100 also shown in FIG.
This rear glass bracket 100 is made of a steel plate like the windshield bracket 54, and has a shape with a bent portion 100A around the periphery. A pair of elongated holes 102 and 104 are bored in the center of the rear glass bracket 100 in the horizontal direction.
Assembly bolt 10 also shown in FIGS. 1 and 8
6,107 is used for passing through. The assembly bolts 106, 107 have a flange 106A in the middle, and are fitted with a synthetic resin filler 60, similar to the case of the windshield bracket 54 shown in FIG.
It is fixed to the window glass 14 with a nut 62.

Further, during assembly, the nuts 108 are screwed into the protruding threaded ends of the assembly bolts 106, 107 to fix the rear glass bracket 100 to the window glass 14. In this case, the long hole 104
A circular hole 110 is communicated with the mounting bolt 1.
07, the nut 108 is temporarily fastened to the nut 108' as shown by the imaginary line in FIG.
08 can be inserted into the circular hole 110, which facilitates assembly.

From a part of the rear glass bracket 100, the first
As shown in FIG. 9, a pin 112 is fixed by caulking or the like and protrudes, and a ball 114 is formed at the tip of this pin 112. This ball 11
4 is pivotally supported within a spherical recess 118 of the rear slider 116, so that the rear slider 116 can rotate.

The rear slider 116 has a substantially disk shape, is accommodated in the rear guide member 18, and has the role of supporting the window glass 14 to the rear guide member 18, similar to the front slider 66 in the front guide member 16. The rear guide member 18 has a substantially C-shaped cross section that opens toward the outside and has leg portions 18A bent at right angles at both ends in the front and rear direction.
It consists of a locking piece 18B bent at a right angle from the tip of the rear slider 116, which restricts the movement of the rear slider 116 in the indoor/outdoor direction and the longitudinal direction of the vehicle. Only movement is now possible.

Like the windshield bracket 54, a wire attachment part 88 protrudes from the rear glass bracket 100, and accommodates a wire hook 120 which is caulked and fixed to the middle part of the wire 22, and is similarly held by a protruding piece 94. Also, similar to the case of the front hook holder 76, this wire attachment portion 88 is coated with a synthetic resin coating 96 to absorb abnormal noise between the wire attachment portion 88 and the wire hook 120.

In this way, the rear glass bracket 100 connects the rear lower part of the windshield 14 to the rear guide member 1.
8 and is connected to the wire 22 to receive driving force.

Front guide member 16, rear guide member 18
is the windshield 1 when viewed from the front and rear directions of the vehicle.
4, the vertically intermediate portion has a curved shape that bulges toward the outdoors. An example of the rear guide member 18 is shown in FIG. 22, which allows the window glass 14, which has a curved surface bulging toward the outside, to be smoothly raised and lowered.

Further, as shown in FIG. 22, the wire 22 between the rear upper pulley 50 and the rear lower pulley 52 is bent by a synthetic resin rear wire guide shoe 122 provided at the intermediate portion of the rear guide member 18. Therefore, the door 10 has an inner plate 10
A part of A is bent toward the outside, so that a recess 124 can be formed to expand the indoor living space. If the rear wire guide shoe 122 is not provided, the wire will also interfere with the door inner plate 10A as shown by the broken line in FIG. Such a structure in which the wire 22 is bent at the intermediate portion is unique to a wind regulator using the wire 22, and cannot be achieved with a conventional wind regulator using an X-shaped arm.

Note that this rear wire guide shoe 122 does not support this rear slider 1 even when the wire attachment portion 88 reaches the same height as shown by the imaginary line in FIG.
It is arranged so as not to interfere with 16. Therefore, when the wire 22 reaches the highest position as shown by the solid line in FIG.
If the rear guide shoe 122, the rear wire guide shoe 122, and the rear lower pulley 52 form a straight folded line, and the wire attachment portion 88 reaches the lower end of the rear guide member, the rear upper pulley 50, the rear wire guide between the shoe 122, the rear wire guide shoe 122, and the wire attachment portion 88;
A folded line forms between the wire attachment portion 88 and the rear lower pulley 52. Further, when the wire attachment portion 88 is located at the upper and lower intermediate portions, the wire 22 does not come into contact with the rear wire guide shoe 122 and forms a folded line between the wire attachment portion 88 and the pulleys 50 and 52.

As shown in FIG. 23, the rear wire guide shoe 122 is attached to the rear guide member 18 via a rear shoe bracket 126. That is, one end of the rear bracket 126 is welded to the rear guide member 18 and the other end protrudes in a direction perpendicular to the longitudinal direction of the rear guide member 18.
As shown in FIGS. 4 and 25, the rear wire guide shoe 122 is inserted into a pair of U-shaped grooves formed by a pair of L-shaped holders 128 protruding from both sides of the rear surface of the rear wire guide shoe 122, and the rear wire guide shoe 122 becomes a rear guide member. 18. A rib 130 protrudes between the L-shaped holders 128 on the back surface of the rear wire guide shoe 122, and the rear wire guide shoe 122 has ribs 130 protruding between the L-shaped holders 128.
6 is held securely.

The sliding surface of the rear wire guide shoe 122 with the wire, that is, the surface on the outside of the vehicle interior, has an arc shape with a predetermined curvature as shown in FIG.
Prevents damage to 2. Furthermore, a pair of stopper pieces 132 protrude from both front and rear sides of the vehicle on the sliding surface of the wire 22 of the rear wire guide shoe 122 at a substantially right angle toward the outside of the vehicle interior. The amount of movement in the forward and backward directions is limited. This movement of the wire 22 in the longitudinal direction of the vehicle is as follows:
This can occur due to tension changes that occur in the wire 22 when the window glass 14 reaches its highest or lowest position.

FIG. 27 shows a front wire guide shoe 1 attached to the middle part of the front guide member 16.
34 is shown. This front wire guide shoe 134 is made of synthetic resin like the rear wire guide shoe 122, and is fixed to the front guide member 16 via a front shoe bracket 136, and its exterior surface in the passenger compartment is in sliding contact with the wire 22. It has become a face.

Also, this front wire guide shoe 134 has a stopper piece 132 like the rear wire guide shoe 122, but it has a stopper piece 132 only on one side in the longitudinal direction of the vehicle; The sliding surface with the wire 22 is an inclined surface 138 where the thickness of the front wire guide shoe 134 is gradually reduced. When the width of the guide shoe is large as described above, the stopper piece 132 can be provided only on one side, and therefore, the front wire guide shoe 134 can be attached to the windshield bracket 54 and the front hook guided by the front guide member 16. There is no interference with the holder 76, and displacement of the wire 22 in the longitudinal direction of the vehicle can be restricted. Also, the wire 22
is shifted in the longitudinal direction of the vehicle and the front guide member 16
22', if this deviation returns to its original state, it will easily climb up the slope 138 and reach the second
It is possible to return to the position shown by the solid line in Figure 7.

FIG. 28 shows an explanation of the mounting angle of the rear upper pulley 50. The rotation axis of this rear atsuppa pulley 50 is the rear atsuppa pulley 50.
Wire 22 leading from to drive unit 20 (direction of arrow Q)
It is perpendicular to the plane containing the rear pulley 5.
It is also preferable to make it perpendicular to the plane containing the wire 22 between the wire hook 120 and the wire hook 120. This reduces the friction between the wire 20 and the groove side surface of the rear upper pulley 50.

This rear pulley 50 and wire hook 12
The wire 22 between the wire 22 and the windshield 14 is shifted between the highest position of the window glass 14, as shown by the solid line in the drawing, and the lowest position of the window glass 14, as shown by the imaginary line, and the included angle is θ. . Therefore, it is preferable that the rotational axis of the rear upper pulley 50 is a plane that further includes a line E that divides the included angle θ into 1/2.

The drive section 20 will be explained with reference to FIGS. 29 to 31.

The base plate 140 is made of a steel plate, has a bent portion 140A around its periphery, has internal threads 142 formed at both end extensions, and is fixed to the inner plate 10A of the door 10 with screws (not shown). ing.

Both ends are caulked to the base plate 140.
A drum shaft 150 protruding from a drum 148 is pivotally supported on the drum case 146 fixed by the drum case 146. A handle shaft 152, which is pivotally supported on the drum 148, is pivotally supported on the base plate 140.

As shown in FIG. 32, a spiral groove 154 is formed on the outer periphery of the drum 148, and both ends of the wire 22 are wound in opposite directions, and wire ends 156 are fixed to both ends of the wire 22. The wire 22 is inserted into the end locking grooves 158 formed at both axial ends of the drum 148.
This prevents the material from slipping out. This allows wire 2
Both ends of the wire 22 are connected via a drum 148, making the wire 22 a closed loop.

In this case, when the drum 148 rotates in one direction,
One end of the wire 22 is unwound from the helical groove 154, and the other end is wound into the helical groove 154.
Handle shaft 152 and base plate 140
A coil spring 160 is provided between the handle shaft 152 and the handle shaft 152 to prevent the handle shaft 152 from rotating in reverse even when tension is applied to the wire 22. Since the function of the coil spring 160 for preventing reverse rotation is well known, a description thereof will be omitted.

A spring case 164 is attached to the drum case 146 with a spring lid 162 in between. The spring case 164 accommodates a spiral spring 166 and locks the outer end of the spiral spring 166. The inner end of this spiral spring 166 is locked to a slit 168 formed in the drum shaft 150, and when the drum shaft 150 rotates in the upward direction of the window glass 14 due to the biasing force of this spring, the self-weight of the window glass 14 is applied. It is designed to give you the power to resist.

A sub-base 170 is fixed to the base plate 140 by caulking, as clearly shown in FIG. This sub-base 170 is bent and formed from a steel plate, and has retainer locking projections 172 and 174 erected from both ends, respectively.

A wire tube 176 is stretched between the retainer locking projection 172 and the rear guide upper bracket 46 of the rear guide member 18. This wire tube 176 is a tube formed of a flexible material such as synthetic resin, and the inside is covered with wires 2.
2 is passing through.

As shown in FIGS. 31 and 33, one end of the wire tube 176 is attached to the wire tube retainer 17.
When the small diameter portion 180 of the wire tube retainer 178 is inserted into the hole 182 formed in the retainer locking projection 172, the stepped portion 184 comes into contact with the retainer locking projection 172. It is locked. The hole 182 is provided with an opening and has a width narrower than the small diameter portion 180 of the retainer to prevent the retainer from coming off.

On the other hand, the other end of the wire tube 176 is connected to the 34th,
Wire tube retainer 1 as shown in Figure 35
86 to the rear guide attachment bracket 46. This wire tube retainer 1
86 is formed with an insertion hole 188 for inserting the wire tube 176.
A wire passage hole 196 is bored coaxially with the wire passage hole 196, and the insertion hole 188 and the wire passage hole 196 are communicated with the outside through a slit 190.

Further, a pair of grooves 192 are bored from both sides of the wire tube retainer 186, and a rectangular groove 192 formed in the rear guide assembly bracket 46 is formed in the wire tube retainer 186.
It is designed to be inserted into the periphery of 4. For assembly, the wire 22 is passed through the slit 190 of the tube retainer 186, the tube 176 with the wire 22 passed through it is inserted into the insertion hole 188, and the rectangular groove 1 of the rear guide attachment bracket 46 is inserted.
It is designed to be installed by inserting a groove 192 into 94. During this assembly, the spacing between the slits 190 is narrowed, so that the insertion hole 188 is reduced to securely hold the wire tube 176.

On the other hand, the retainer locking protrusion 17 of the sub-base 170
4 and the front lower guide bracket 40 of the front guide member 16 is a wire tube 20.
0 is crossed. This wire tube 20

A wire tube retainer 186 shown in FIG. 5 is applied.

Sub base 170 of this wire tube 200
The side ends are inserted into the wire tube retainer 202 shown in FIGS. 31 and 36. The small diameter portion 180 of the wire tube retainer 202 has a longer axial length than the small diameter portion 180 of the wire tube retainer 178, and is inserted into the circular hole 204 of the retainer locking projection 174 so that the amount of insertion can be changed. A compression coil spring 206 is interposed between the retainer locking protrusion 174 and the wire tube retainer 202.
is urged in a direction away from the retainer locking protrusion 174. As a result, tension is always applied to the wire 22 between the drive section 20 and the front guide lower bracket 40, so that the closed loop of the wire 22 always has an appropriate tension. The compression coil spring 206 also prevents the wire tubes 176, 200, 210 from coming off each bracket.

As shown in FIG. 1, the drive unit 20 arranged in this manner is arranged in front of the front guide member 16 and the rear guide member 18, which are arranged parallel to each other.
