Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a code switch for detecting whether an external force such as a pressing force has acted within a predetermined range.

[0002]

2. Description of the Related Art An insulated and elastic long tube is used as a cord switch which is long in its entirety and can detect that a pressing force is applied even if any part along the longitudinal direction is pressed. 2. Description of the Related Art There is a cord switch of a type in which long electrodes are fixed to an inner peripheral portion of an outer skin portion in a state of being separated from each other inside an outer shell portion. In this type of code switch, when the outer cover is elastically deformed by the pressing force, the electrodes come into contact with each other and short-circuit, so that the electric resistance value of the electric circuit including the electrodes is sharper compared to the state before the contact. Change. By detecting a sudden change in the electric resistance value or the current value, it is configured to recognize that a pressing force has acted on the outer skin portion.

[0003]

In such a code switch, the electrodes must be electrically connected to a computer or the like. In this case, it is common to connect the other end of the lead wire, one end of which is directly or indirectly electrically connected to a computer or the like, to the longitudinal end of the electrode.

Here, Japanese Patent Application Laid-Open No. 61-248310 discloses an example of a method for electrically connecting an electrode and a lead wire.

The method disclosed in Japanese Patent Application Laid-Open No. 61-248310 will be briefly described. A part of the outer periphery of the outer skin is locally cut off near the end of the outer skin to expose an electrode in the outer skin to the outside. After fixing the end of the lead wire to the electrode from the cut portion, the cut portion is covered with an insulating member having elasticity.

However, according to this method, the lead wire is exposed outside the cut portion covered with the insulating member. Therefore, when foreign matter or the like comes into contact with the lead wire, the lead wire is pulled by the pressure from the foreign matter. As a result, the connection between the lead wire and the electrode may be broken.

An object of the present invention is to provide a cord switch in which an electric connection between a terminal portion of an electrode and the outside is strong in consideration of the above fact.

[0008]

According to a first aspect of the present invention, there is provided a cord switch comprising: a hollow outer skin portion elastically deformable by an external pressure;
A plurality of electrodes that are provided inside the outer skin portion and are separated from each other and whose terminal portions are drawn out from the outer skin portion, and are connected to the terminal portions of the plurality of electrodes and in the direction in which the terminal portions of the electrodes are drawn out. A connection member extending in a direction intersecting with the connection member and connecting the electrodes to determination means for determining whether the plurality of electrodes have come into contact with each other; and an end portion of the skin portion provided at an end of the skin portion While covering the connecting portion between the connecting member and the terminal portion of the plurality of electrodes, and holding the connecting member in a state of extending in a direction intersecting the drawing direction of the terminal portion of the electrode. And a sealing member.

According to the cord switch having the above-described structure, the terminal portion of the electrode is drawn out from the end of the outer skin portion, and the connecting member is connected to the terminal portion so that the terminal portion intersects with the drawing direction of the terminal portion. The connecting member extends toward and is connected to the determination means.

Here, in the present code switch, the sealing member seals the end of the outer cover, thereby preventing foreign matter such as water droplets from entering the inside from the end of the outer cover.
The sealing member covers the connection between the connection member and the terminal portion of the electrode, and the connection member is sealed in a state where the connection member is pulled out in a direction intersecting the drawing direction of the terminal portion of the electrode. It is held by the stop member. Therefore, the connection between the electrode and the connection member can be strengthened, and disconnection and the like can be prevented.

Further, since the connecting member is drawn out of the sealing member regardless of the drawing direction of the terminal portion of the electrode,
For example, in a case where the connection member pulled out from the sealing member is made to penetrate the support that supports the outer skin portion, and the connection member is disposed on the opposite side to the outer skin portion via the support, the support body is used. If the connecting member is pulled out from the sealing member in the penetrating direction when penetrating, the exposed portion of the connecting member on the outer skin side of the support is eliminated or reduced, and foreign matter may touch the exposed portion of the connecting member. It is eliminated or reduced, and disconnection or the like due to this can be prevented.

Further, if the direction in which the connecting member is pulled out from the sealing member is made to correspond to the connecting direction of the connecting member when the connecting member is directly or indirectly connected to the judging means, the connection is made outside the sealing member. The connecting member can be directly or indirectly connected to the determination means without bending or bending the member,
The handling of the connecting member in the work of connecting the connecting member to the determination means is facilitated.

A cord switch according to a second aspect of the present invention is the cord switch according to the first aspect, wherein the closing portion is capable of being fitted into a hole formed in a support for supporting the outer skin portion and closing the hole in the fitted state. Is formed on the sealing member, and the connection member is drawn out from the closing portion.

According to the cord switch having the above structure, the sealing member is formed with the closing portion, and the closing portion is fitted into the hole of the support to close the hole. Foreign matter is prevented from entering. Here, in this cord switch, the connection member is pulled out from the closing portion,
Thereby, the connection member is provided on the opposite side to the outer skin portion via the support. For this reason, the connecting member is not exposed on the outer skin side of the support, and the foreign matter does not touch the exposed portion of the connecting member, so that disconnection or the like due to this can be reliably prevented.

FIG. 9 is a perspective view of a vehicle 12 to which a cord switch 10 according to a first embodiment of the present invention is applied, as viewed from the front side. FIG. A perspective view from the rear side is shown.

As shown in FIG. 7, the vehicle 12 is provided with a door panel 14. This door panel 14
It is formed so that it can fit into an opening 20 formed on the side wall 18 of the vehicle body 16 for occupant getting on and off a rear seat (not shown). When the door 20 is closed, the door panel 14 is closed.
And the outer surface of the side wall 18 are formed substantially flush.

At the upper end of the door panel 14, a substantially U-shaped door frame 22 which is opened downward is provided integrally, and forms a window frame of a window glass 24 provided on the door panel 14. doing. Also, door panel 1
A window regulator (not shown) is provided in the interior of the vehicle 4 (that is, between the outer panel 26 and the inner panel 28 shown in FIG. 2 or FIG. 3), and the interior of the vehicle 12 (for example, inside the door panel 14 or when driving). The window glass 24 can be moved up and down by operating a switch (not shown) provided near the seat.

As shown in FIG. 7, a bracket 30 extending inward in the vehicle width direction is integrally fixed to the lower end of the door panel 14. As shown in FIG. 8, a roller 32 is pivotally supported at the tip end of the bracket 30. Further, the roller 32 is provided on a guide rail 34 provided on the back side of a floor panel (not shown) of the vehicle 12. It is in contact with the outer surface in the vehicle width direction. This roller 32
Is generally the vehicle 1 while rolling due to friction with the guide rail 34.
2 can be moved in the front-back direction. However, as shown in FIG. 8, the outer end of the guide rail 34 in the vehicle width direction is inclined toward the inside in the vehicle width direction at the front end side, and the roller 32 rolls along this inclined portion. The roller 32 moves inward in the vehicle width direction while moving forward of the vehicle 12, and the door panel 14, which has slid along the front-rear direction of the vehicle 12 on the outer side in the vehicle width direction on the side wall 18, moves inward in the vehicle width direction. It displaces and fits into the opening 20. Also,
The roller 32 moves outward in the vehicle width direction while moving rearward of the vehicle 12, and the door panel 14 that has been fitted into the opening 20 moves outward in the vehicle width direction of the side wall 18 and moves along the front-rear direction of the vehicle 12. To be slidable.

As shown in FIG. 8, a pulley 36 and a drive roller 38 that rotate around the vertical axis of the vehicle 12 are provided inside the guide rail 34 in the vehicle width direction. It has been hung. The bracket 30 described above is fixed to the endless belt 40,
When the bracket 30 moves by the rotation of the endless belt 40, the rollers 32 roll along the guide rails 34, and the door panel 14 further moves.

The drive roller 38 is connected to a slide actuator 50 (see FIG. 7) disposed on the back side of the floor panel, and is provided with a slide motor 52 (see FIG.
0), the endless belt 40 rotates. Further, as shown in FIG. 10, the slide actuator 50 includes a slide driver 54. The slide motor 52 is electrically connected to a computer 56 constituting control means via a slide driver 54, and furthermore, an operation switch 58 provided near the driver's seat of the vehicle 12 via the computer 56.
(See FIG. 7).
8, the computer 56 sends a predetermined signal to the computer 56, and the computer 56 sends a predetermined signal to the slide driver 54 to operate the slide driver 54, and the slide driver 54 transfers the power from the power supply 48 to the slide motor 52. The slide motor 52 is operated or stopped by supplying or stopping the supply of electric power. Thus, the door panel 14 can be slid (open / closed).

That is, the mechanism for opening and closing the door panel 14 of the vehicle 12 employs a so-called automatic sliding door device which opens and closes the door panel 14 by sliding it back and forth by the driving force of the slide motor 52.

As shown in FIG. 10, the slide actuator 50 has a position detecting device 60. The position detection device 60 is provided corresponding to the rotation axis of the slide motor 52, and can detect the rotation amount of the rotation axis from the time when the slide motor 52 starts driving.

The rotation of the rotation shaft of the slide motor 52 is transmitted to an output shaft via a reduction gear, and the rotation of the output shaft rotates the drive roller 38 (see FIG. 8) to rotate the endless belt 40. Then, the door panel 14 is configured to slide. Therefore, the amount of sliding of the door panel 14 is proportional to the amount of rotation of the output shaft, and the amount of rotation of the output shaft is proportional to the amount of rotation of the reduction gear and the rotating shaft. Therefore, the sliding amount of the door panel 14 can be calculated by measuring the rotation amount of the rotating shaft from the start of the slide motor 52.

As an example of the configuration of the position detecting device 60, a plurality of slits penetrating along a thickness direction of the rotating disk that rotates with the rotating shaft are formed at predetermined angles around the rotating shaft. A light-emitting element and a light-receiving element are arranged so as to sandwich the rotating disk, and only when the rotating disk rotates and the slit faces the light-emitting element, the light-receiving element emits light from the light-emitting element and receives light passing through the slit. There is a configuration in which the number of light receptions by the element is counted to calculate the amount of rotation of the rotating shaft. In addition, one of the sliding contacts is brought into contact with a conductive plate such as a metal plate that rotates together with the rotating shaft, and a conductive pulse piece that is formed so as to radially protrude from the outer peripheral portion of the conductive plate around the rotation axis at a predetermined angle. The other sliding contact is arranged so that it can be contacted, and when the conductive board rotates and the pulse piece comes into contact with the other sliding contact, both sliding contacts conduct through the pulse piece and the conductive board. There is also a configuration in which the number of conductions of both sliding contacts is counted to calculate the amount of rotation of the rotating shaft.

In the present embodiment, the position detecting device 6
Although 0 is a configuration for detecting the rotation amount of the rotation shaft of the slide motor 52, the configuration of the position detection device 60 is not limited to this, and any configuration that directly or indirectly detects the position of the door panel 14 can be used. Any configuration may be used. As an example of a configuration for detecting the position of the door panel 14, for example, a light emitting element is provided inside the door panel 14,
When the door panel 14 slides to a predetermined position on the side wall 18 of the vehicle body 16, a light receiving element is provided at a position facing the light emitting element, and when the light receiving element receives light emitted from the light emitting element, the door panel 14 is moved to the predetermined position. A configuration for detecting that a slide has occurred is conceivable.

On the other hand, as shown in FIG. 9, a bracket 62 extending inward in the vehicle width direction is provided at an intermediate portion and an upper end portion of the door panel 14 in the vertical direction. Rollers (not shown) are provided at the distal ends of these brackets 62, each of which enters a guide groove 50 of a guide rail 64 provided at an appropriate position of the vehicle 12 in a state where it is prevented from falling off, and this guide rail is provided. Move along 64. That is, the door panel 14 is supported on the side wall 18 of the vehicle body 16 via the guide rail 64 and the bracket 62, and moves while being guided by the guide rails 34 and 64 by the driving force of the slide actuator 50 described above.

The guide rail 64 is also a guide rail 3.
Similarly to 4, the front end side is inclined inward in the vehicle width direction. In this inclined portion, the roller of each bracket 62 moves inward in the vehicle width direction while moving forward of the vehicle 12 along the guide groove 66 of the guide rail 64, or moves outward in the vehicle width direction while moving backward of the vehicle 12. Moving. During this movement, the door panel 14 moves in and out of the vehicle width direction.

As shown in FIG. 7, a closer actuator 70 is disposed inside the door panel 14. As shown in FIG. 10, the closer actuator 70 includes a closer driver 72 constituting control means and a closer motor 74 as drive means. The closer driver 72 is electrically connected to the computer 56, and the door panel 14 is slid toward the direction in which the opening 20 is closed by the driving force of the slide motor 52 (ie, toward the front of the vehicle 12). When the above-described position detection device 60 detects the sliding of the door panel 14 until the door panel 14 is just before completely closing the opening 20, the computer 56 operates the closer driver 72 to send the closer motor 74 to the closer motor 74. It is driven by supplying electric power. Thereby, the closer motor 74 activates a lock mechanism (not shown) of the door panel 14 such as a latch provided on the door panel 14 when the door panel 14 is fitted into the opening 20, and
The door panel 14 is guided to a predetermined position in the opening 20 where the door panel 14 can be locked by the lock mechanism.

These electrodes 88 to 94 are spaced apart from each other via the cross hole 86 near the center of the cross hole 86 and are spirally arranged along the cross hole 86, and are integrally fixed to the inner peripheral portion of the cross hole 86. I have. Therefore, the electrodes 88 to 94 are bent by the outer skin portion 64 being elastically deformed. In particular, if the outer skin portion 84 is elastically deformed to such an extent that the cross hole 86 is crushed, the electrodes 88 to 94 are bent and the electrode 88 becomes the electrode 90 or the electrode 90. The electrode contacts the electrode 94 or the electrode 92 contacts the electrode 90 or the electrode 94 to cause a short circuit. When the outer skin portion 64 is restored, the electrodes 88 to 94 are also restored.

Is held between the other vertical wall 102 so that both ends face each other along the longitudinal direction, is gripped in a state of being wrapped by the other swaged piece 108 which is swaged, and is fixed by welding. Have been. Thus, the electrode 90 and the electrode 92 are electrically connected via the resistor 98.

On the other hand, as shown in FIG. 1, a plurality of vertical walls 11 are provided on the back side (the side shown in FIG. 1) of the terminal plate 96.
2 are erected. The lower ends of the electrodes 88 and 94 are arranged between the vertical walls 112, and each is held by being swaged by the swaged piece 108 and fixed by welding. Each of the caulking pieces 108 to which the terminal portions of the electrodes 88 and 94 are fixed is attached to the end of the pair of lead wires 122 and 124 of the cord 120 as a connecting member. It is fixed similarly to. These lead wires 122 and 124 are elongated in a direction substantially perpendicular to the direction in which the electrodes 88 and 94 are drawn out (that is, pulled out from the caulking piece 108 radially outward of the outer cover 84). As shown in FIG. 2, the door panel 14 is provided inside the door panel 14 through a through hole 126 formed at the front end of the door panel 14, that is, between the outer panel 26 and the inner panel 28 that constitute the door panel 14. Have been. As shown in FIG.
124, that is, the cord 120 is electrically connected to a power source, and the above-described electrodes 88 and 94 are connected to the cord 12.
Electric power is supplied from a power supply via the power supply 0. Note that FIG.
Although the cord 120 is illustrated as being directly connected to the power supply, other connecting means may be interposed between the cord 120 and the power supply. In particular, the present embodiment has a configuration in which the code switch 10 is applied to an automatic sliding door device.
As described above, the door panel 14 is configured to slide. When the power supply is provided on the vehicle body 12 side in such a configuration (that is, in the case of a configuration in which the door panel 14 moves relatively to the power supply), for example,
In some cases, it is better to connect the cord 120 to the power supply via a sliding contact or the like.

On the other hand, although not shown in detail, the outer skin 84
A terminal plate 96 is also provided at the upper end of. However, no resistor 98 is provided on the upper terminal plate 96. On the front side of the upper terminal plate 96, the upper end of the electrode 88 and the upper end of the electrode 92 are swaged similarly to the lower ends of the electrodes 88 to 94.
The upper end of the electrode 90 and the upper end of the electrode 94 are electrically connected to the caulking piece 108 by welding on the back side of the terminal plate 96.

That is, as shown in the circuit diagram of FIG. 11, the current from the power supply is supplied from the electrode 88 to the electrode 92 and the resistor 9

If any one of the contacts 94 makes a short circuit, the current flows without passing through the resistor 98, so that the resistance value of the entire circuit decreases and the current value increases. Here, as shown in FIG.
The current flowing out of the device returns to the power supply via the current detecting element 132 as a judging means for transmitting a signal when a current equal to or more than a predetermined value is detected. When the current increases, a signal is transmitted from the current detecting element 132, and the signal is received by the computer 56 (see FIG. 10) which is electrically connected to the current detecting element 132.

Further, as shown in FIG.

The protector 136 includes a holding portion 138 formed in a cylindrical shape along the longitudinal direction. The inner diameter of the holding portion 138 is substantially the same as the outer diameter of the outer skin portion 84, and holds the sensor body 82 inserted therein. Therefore, in practice, the holding portion 138 is elastically deformed by receiving the external pressure, so that the outer skin portion 84 is indirectly elastically deformed by receiving the external pressure. A mounting portion 140 is formed so as to protrude radially outward from a part of the outer periphery of the holding portion 138.

As shown in FIG. 2 and FIG.

When the plate-shaped bracket 146 having an L-shaped cross section fixed to the inner side) is inserted,
The holding piece 144 is elastically deformed, and the restoring force (elastic force) presses the bracket 146 against the other inner wall side in the mounting groove 142 to hold the bracket 146. Thus, the code switch 10 is fixed to the door panel 14.

Further, as shown in FIGS. 1, 5, and 6, a mold 150 is provided at the lower end of the outer cover 84. The mold 150 is formed of an insulating and thermoplastic rubber material or a synthetic resin material, and its upper end is in close contact with the outer periphery of the lower end of the protector 136. Thereby, the outer skin portion 84 and the lower end portion of the protector 136 are sealed. Further, inside the mold 150, an electrode 88 pulled out from the lower end of the outer cover 84 is provided.

Next, the operation and effect of the present code switch 10 will be described. The code switch 10 attached to the door panel 14 slides with the door panel 14 when the door panel 14 slides by the driving force of the slide motor 52. When the door panel 14 slides rearward of the vehicle 12 and the opening 20 is opened, the slide motor 52 starts driving and the door panel 1
When the front panel 4 is slid forward of the vehicle 12 and foreign matter is present on the front side of the door panel 14, the code switch 10 sliding with the door panel 14 comes into contact with the foreign matter and the code switch 10 moves the foreign matter forward of the vehicle 12. Press toward the side. When a pressing reaction force from a foreign object acts on the cord switch 10 at this time, the protector 136 and the outer skin portion 84 are elastically deformed by the pressing reaction force, and the outer skin portion 84 is deformed.
, Any of the electrodes 88 to 94 contact each other. In this state, as described above, the electric resistance of the electric circuit including the electrodes 88 to 94 (see FIG. 11) changes, and the current value flowing through the circuit sharply increases. When the current detection element 132 detects this rise in the current value, the current detection element 132 transmits a signal, and the transmitted signal is sent to the computer 56. The computer 56 that has received the signal operates the slide driver 54 to reversely drive the slide motor 52 and slide the door panel 14 toward the rear side of the vehicle 12 again. This prevents foreign matter from being caught by the door panel 14.

As shown in FIG. 1, FIG. 5, and FIG. 6, in the present code switch 10, the terminal portion (that is, the end portion in the longitudinal direction) is sealed by the mold 150. Therefore, foreign matter such as water droplets does not enter from the end of the outer cover 84. Moreover, this mold 15
Numeral 0 encloses the terminal plate 96 therein, around each member such as the resistor 98, the connection portion between the electrodes 90, 92 and the resistor 98, and the electrodes 88, 94 and the lead wire 122,
A rubber material or a synthetic resin material constituting the mold 150 is in close contact with the periphery of the connection portion with the mold 124, and these are held by the mold 150 from the outside. Therefore, disconnection or the like of the connection portion due to an impact from the outside of the mold 150 or the like is prevented.

Further, as shown in FIG. 1, in the present code switch 10, the lead wires 122 and 124 are
The mold 150 is pulled out from the rear end of the mold 150 in a direction perpendicular to the drawing direction. For this reason,
Lead wires 122 and 12 drawn out of mold 150
4 is pulled into the door panel 14 through the through hole 126 as it is (that is, in a state where it is pulled out). Moreover, the rear end of the mold 150 is the door panel 1.
4 is in contact with the front end of lead wires 122, 12
4 is not exposed on the front side of the door panel 14. Therefore,
No foreign matter or the like comes into contact with the lead wire at the front side of the door panel 14, and disconnection or the like due to this can be prevented. Also, the lead wire 12 drawn out of the mold 150
2 and 124 can be passed through the through-hole 126 as it is, so that the door panel 1 of the cord switch 10
4, the lead wires 122, 1
There is no need to bend the lead wires 122 and 124 in order to penetrate the lead wires 24, and the handling of the lead wires 122 and 124 becomes extremely easy. Thereby, the workability in the assembling process of the code switch 10 can be improved, and the assembling cost can be reduced. Further, in the present embodiment, the cord switch 10 is provided on the door panel 14 of the vehicle 12, and the opening 20 that the door panel 14 opens and closes is a portion through which the occupant passes. Therefore, as described above, by pulling out the lead wires 122 and 124 from the rear end of the mold 150 and passing the lead wires 122 and 124 through the through-hole 126 as they are and inside the door panel 14, the lead wires 122 and 124 are basically noticeable. Never
As a result, the appearance of the vehicle 12 can be improved.

In the present embodiment, the door panel 14
Although the rear end of the mold 150 contacts the front end of the door 150, the rear end of the mold 150 may be separated from the front end of the door panel 14. In this case, although the lead wires 122 and 124 are slightly exposed at the front side of the door panel 14, the exposed portions are limited between the front end of the door panel 14 and the rear end of the mold 150. It hardly impairs the function or effect that has been performed.

In this embodiment, the lead wire 12
2 and 124 are connected to the electrodes 88 and 94, that is, from the portion fixed by the caulking piece 108 to the electrodes 88 and 94.
Is extended in a direction perpendicular to the direction in which the electrode 8 is pulled out, and is pulled out of the mold 150 as it is.
It suffices if they intersect the drawing directions of 8, 94. In addition, the lead wires 122 and 124 may be connected to the electrodes 88 and 94 in any way as long as the direction of extraction from the mold 150 intersects the direction of extraction of the electrodes 88 and 94. As shown in FIG. 12, lead wires 122 and 124 are
8, 94, and is curved inside the mold 150 and is drawn out of the mold 150 in a direction intersecting the drawing direction of the electrodes 88, 94 (a direction orthogonal to FIG. 12). Is also good.

Next, another embodiment of the present invention will be described. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

FIG. 13 is a sectional view of a terminal portion of the cord switch 160 according to the second embodiment of the present invention, and FIG. 14 is a perspective view of a terminal portion of the cord switch 160. I have. As shown in FIG. 14, the cord switch 160 is attached to the mounting portion 164 of the protector 136.
Is different from the first embodiment in that the mounting portion 16
4 is provided with a mounting groove 166. This mounting groove 16
6 has an opening end whose width dimension is substantially the same as the thickness of a plate-shaped bracket 168 having an L-shaped cross section fixed to the inside of the door panel 14 (more specifically, the inner side surface of the inner panel 28). However, the bottom portion is a wide portion 170 having a larger width dimension than the opening end side. The wide portion 170 corresponds to the folded portion 172 formed at the tip of the bracket 168. When the folded portion 172 is inserted to the wide portion 170, the folded portion 172 engages with the inner wall of the wide portion 170. As a result, the bracket 168 does not fall out of the mounting groove 166. Thereby, the code switch 160 is fixed to the door panel 14.

As shown in FIGS. 13 and 14, in the present code switch 160, the structure of the mold 180 as a sealing member is different from that of the mold 150 of the code switch 10 according to the first embodiment. Grommet portion 182 as a closing portion from the rear end toward the rear
Are formed to protrude.

The grommet portion 182 has a substantially columnar shape, and its outer diameter can be fitted into the through hole 126 of the door panel 14. The grommet portion 182 closes the through hole 126 in the fitted state. Therefore, intrusion of foreign matter such as water droplets from the through hole 126 is prevented by the grommet portion 182. The grommet portion 182 has a retaining portion 184.
Are formed. The retaining portion 184 has an outer diameter larger than the inner diameter of the through hole 126 at the base end and an outer diameter 12 at the distal end.
6 and a grommet 1
When fitting 82 into the through hole 126, the distal end of the retaining portion 184 is pushed into the through hole 126. Although the base end side of the retaining portion 184 has a diameter larger than the inner diameter of the through hole 126,
Is formed of a rubber material or a soft synthetic resin material similarly to the mold 150,
When pushed in, the base end side of the retaining portion 184 is elastically deformed, so that the base end side of the retaining portion 184 can pass through the through hole 126. When the retaining portion 184 penetrates, the base end of the retaining portion 184 comes into contact with the back surface of the front end of the door panel 14, so that the grommet portion 182 does not come out of the through hole 126.

Further, the above-described lead wires 122 and 124
Is pulled out from the tip of the retaining portion 184 through the grommet portion 182. Therefore, by fitting the grommet portion 182 into the through hole 126, the lead wire 12
The portions of the molds 2 and 124 drawn out of the mold 180 are already located inside the door panel 14 (in other words, the lead wires 122 and 124 pass through the through holes 126 when the grommet portion 182 passes through the through holes 126). . For this reason,
In the second embodiment, the same operation as in the first embodiment can be achieved, and the same effect can be obtained. Moreover,
Even if the rear end of the mold 180 is separated from the front end of the door panel 14, the lead wires 122 and 124 are not exposed to the front side of the door panel 14.

In addition, in the opening such as the through hole 126 of the door panel 14, it is basically necessary to arrange a closing member such as a grommet or the like to close the opening so as to prevent foreign matters such as water droplets from entering. However, in the present embodiment, the mold 18
Since the grommet portion 182 is formed at 0, there is no need to use a separate closing member, and the number of components can be reduced.
