Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic opening / closing device such as a motor-driven window regulator and the like, and more particularly to an automatic opening / closing device having a foreign matter detecting function for detecting foreign matter being caught by a moving body such as a window glass or a door panel. Related to the device.

[0002]

2. Description of the Related Art In recent years, an opening and closing device for a window glass of a vehicle includes:
A so-called power window device using the driving force of a motor is employed. In this type of power window device, a pinch detection mechanism (pinch detection device) that prevents pinching of foreign matter between the window frame and the window glass when closing the window glass is provided. As such an entrapment detection mechanism, for example, a string-shaped pressure-sensitive sensor is arranged along a window frame, and when a foreign object that has received a pressing force from the window glass that is closing and closing presses the pressure-sensitive sensor. The pressure is detected to detect the entrapment of foreign matter, and a control means such as a computer stops the motor or drives the motor in reverse based on the detection result.

[0003] Usually, a window frame of a vehicle is provided with a weather strip formed of a flexible synthetic resin material, and the window frame is closed by pressing an end portion of the window glass against the weather strip. It has become so. A pressure sensor is embedded in this weather strip, and the lead wire drawn out from the pressure sensor is used as it is in the window glass storage portion (for example,
A configuration is also conceivable in which it is drawn into the door panel and electrically connected to the control means arranged in the storage section.

However, as described above, since the window glass is pressed against the weather strip, the weather strip is elastically deformed by the pressure from the window glass, and the pressure from the window glass is transmitted through the weather strip to the pressure-sensitive sensor. May act on In such a case, the control unit mistakenly recognizes that the window glass has caught the foreign matter even though the window glass has not caught the foreign matter. Therefore, in consideration of such a case, it is preferable to dispose the pressure-sensitive sensor along the window frame on the side of the weather strip without embedding the pressure-sensitive sensor in the weather strip. One means for this is to support the pressure sensor in the garnish between the garnish and the weather strip, which are provided closer to the vehicle interior than the weather strip and decorate the interior side of the window frame. . When the pressure-sensitive sensor is arranged in this manner, erroneous detection of the pressure-sensitive sensor due to the elastic deformation of the weather strip can be prevented.

[0005]

The above-mentioned control means such as a computer is provided inside a door panel or a predetermined portion of a vehicle body, and is connected to one end of a conductive means such as a cord provided in the door panel. Have been. The other end of the conductive means is drawn out of the door panel from a draw-out opening formed at the upper end of the door panel, and is connected to a terminal portion of the pressure-sensitive sensor via a connecting means such as a connector.

However, in such a configuration, since the connector and its vicinity are exposed to the outside, there is a problem that the appearance in the vicinity is deteriorated.

An object of the present invention is to provide an automatic opening / closing device, such as a power window device, capable of preventing the appearance quality from being deteriorated in the vicinity of a sensor terminal in consideration of the above fact.

[0008]

According to a first aspect of the present invention, there is provided an automatic opening / closing device which is housed inside a moving body housing and which opens and closes by the driving force of a driving means, and a closing movement end point of the moving body. A contact portion with which the moving body that has moved to the closing movement end point is provided, and a longitudinal portion is formed along the contact portion, and a side portion of the contact portion and at least a part thereof are the contact portion. A pressure-sensitive sensor that is disposed closer to the moving body storage unit, elastically deforms by the pressing force from the moving body storage unit side than the contact unit, and detects the pressing force, and a side of the contact unit. A support that is disposed along the contact portion and supports the pressure-sensitive sensor, and one end in the longitudinal direction of the pressure-sensitive sensor that penetrates a through hole formed in the support and is retracted into the sensor terminal receiving portion And

According to the automatic opening / closing device having the above structure, at least a part of the moving body closed by the driving force of the driving means in the closing movement direction side comes out of the moving body housing portion and approaches the contact portion. When the moving body reaches the closing movement end point, the end in the closing movement direction of the moving body comes into contact with the contact portion. When the moving body comes into contact with the contact portion, the space between the moving body storage section and the contact portion is closed by the moving body.

If foreign matter is present on the moving side of the moving body in the closing movement direction, the end of the moving body on the closing movement side contacts the foreign matter before contacting the contact portion, The moving body presses the foreign matter toward the closing movement direction, moves the foreign matter toward the closing movement direction, and approaches the contact portion and the pressure-sensitive sensor arranged beside the contact portion. Since at least a part of the pressure sensor is disposed closer to the moving body storage section than the contact section, a foreign object approaching the contact section approaches the pressure sensor before contacting the contact section. Then, the pressure sensor is pressed in the closing movement direction to elastically deform the pressure sensor. The pressure-sensitive sensor detects the pressing force from the foreign object by elastically deforming by the pressing force from the foreign object (that is, the pressing force from the moving body storage unit side),
Thereby, it is detected that the foreign substance exists between the moving body and the contact portion.

In this automatic opening and closing device, the pressure-sensitive sensor is supported by a support member arranged along the contact portion on the side of the contact portion. On one end side, a through hole is formed in the support, and the pressure sensitive sensor penetrates this through hole and is drawn into the sensor terminal housing.
Therefore, the terminal processing portion of the pressure-sensitive sensor by the connecting means such as the connector is not exposed to the outside. The sensor terminal housing is also provided integrally at the end of the moving body housing in the closing movement direction, and is connected to the terminal side of the pressure-sensitive sensor or the terminal portion of the pressure-sensitive sensor via the connection means described above. It is possible to draw in the conductive means such as the cord or the like into the movable body storage portion without exposing the conductive means to the outside. in this way,
In this automatic opening and closing device, the terminal processing part of the pressure-sensitive sensor, the connecting means such as a connector provided in the terminal processing part, and the exposure of the conductive means such as a cord can be prevented, so that the appearance quality can be improved. .

[0012] The automatic opening and closing device according to the second aspect is the first aspect.
The present invention according to the above, further comprising a holding unit configured to include a holding unit that holds the pressure-sensitive sensor, and a holding unit that is formed integrally with the holding unit and holds the support.
The pressure-sensitive sensor is supported by the support via the holding means.

In the automatic opening / closing device having the above-described structure, the pressure-sensitive sensor is held by the holding portion of the holding means, and the supporting body is held by the holding portion integrated with the holding portion. A sensor is supported on the support. As described above, in the automatic opening / closing device, the pressure-sensitive sensor can be mounted on the support simply by holding the support between the holding portions, so that the assemblability of the pressure-sensitive sensor to the support is improved.

The automatic opening and closing device according to the third aspect is the first aspect.
In the present invention described above, the holding portion of the holding means,
A low-rigidity portion having a lower rigidity than the pressure-sensitive sensor and located on the side of the moving body housing portion of the pressure-sensitive sensor, and having a higher rigidity than the pressure-sensitive sensor and opposite to the moving body housing portion of the pressure-sensitive sensor; And a high-rigidity portion located on the side, and is formed in a tubular shape capable of storing the pressure-sensitive sensor.

According to the automatic opening / closing device having the above structure, since the low-rigidity portion of the holding portion is located on the side of the moving body housing portion of the pressure-sensitive sensor, the foreign matter that is moved by being pressed by the moving body that moves closed is held. Abutting against the low-rigidity part of the part to press the low-rigidity part. Since the low-rigidity portion has lower rigidity than the pressure-sensitive sensor, the low-rigidity portion is easily elastically deformed if a pressing force enough to elastically deform the pressure-sensitive sensor acts on the low-rigidity portion. For this reason, the pressure-sensitive sensor can receive the pressing force from the foreign material without the pressing force from the foreign material being hindered by the holding unit, and can reliably and quickly detect the foreign material.

On the other hand, on the opposite side of the low-rigidity portion via the pressure-sensitive sensor (ie, on the opposite side of the moving-body storage portion with respect to the pressure-sensitive sensor), the high-rigidity portion of the holding portion is provided. Is located. Since the high-rigidity portion has higher rigidity than the pressure-sensitive sensor, the high-rigidity portion does not elastically deform together with the pressure-sensitive sensor that receives the pressing force from the foreign matter. Therefore, it is possible to prevent the pressure sensor having received the pressing force from the foreign object from moving without being elastically deformed, and as a result, it is possible to detect the foreign object reliably and quickly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS <Structure of First Embodiment> FIG.
1 shows a side view of a door panel 12 of a vehicle to which a power window device 10 as an automatic opening / closing device according to a first embodiment of the present invention is applied. The door panel 12 includes two panel members, an inner panel and an outer panel (detailed illustration is omitted), and a window glass 14 as a moving body can be stored between the inner panel and the outer panel. Has become. Therefore, in the present embodiment, the door panel 12 corresponds to the moving body storage section according to the first aspect of the present invention.

The window glass 14 is mechanically connected to a motor 66 of a window regulator 62 as driving means, which will be described later, and is raised and lowered by the driving force of the motor 66.

As shown in FIG. 3, this window glass 14
The roof panel of the vehicle corresponds to the upper end of the window glass 14 when the vehicle has moved up and reached the end point of the movement, and the roof panel of the vehicle has a waist as a contact portion formed of a synthetic resin material having a rigidity equivalent to that of a rubber material. The strip 16 is disposed, and when the window glass 14 moves up and reaches the end point of the movement, the window glass 1 is moved.
The upper end of 4 contacts or presses against the weather strip 16.

A garnish 18 as a support is disposed near the weather strip 16 and on the vehicle interior side of the window glass 14. The garnish 18 is formed of a synthetic resin material having a predetermined rigidity, and decorates the interior of the vehicle. A sensor support portion 20 is formed at a substantially lateral end of the garnish 18 in the left-right direction of the vehicle. The sensor support portion 20 is formed by bending a substantially vehicle lateral direction end of the garnish 18 substantially downward of the vehicle. The sensor support 20 supports a pressure-sensitive sensor 30.

The garnish 18 is made of an insulating elastic material such as rubber or soft synthetic resin material.
Of the sensor main body 32 is formed in a long shape that is elongated along substantially the lateral end of the vehicle. A cross hole 3 having a cross-shaped cross section is provided inside the outer skin portion 34.
6 are formed along the longitudinal direction of the outer skin portion 34. The cross hole 36 is gradually displaced around the center of the outer skin portion 34 along the longitudinal direction of the outer skin portion 34.

An electrode as an electrode which is formed into a long string having flexibility by twisting a conductive thin wire such as a copper wire inside the outer sheath portion 34 and is covered with a conductive rubber. Lines 38, 40, 42, 44 are provided.
These electrode wires 38 to 44 constitute the sensor main body 32,
As shown in FIG. 5, in the vicinity of the center of the cross hole 36, they are spaced apart from each other via the cross hole 36, are spirally arranged along the cross hole 36, and are integrally fixed to the inner peripheral portion of the cross hole 36. ing. Therefore, the electrode wires 38 to 44 are bent by the elastic deformation of the outer skin portion 34, and particularly, if the outer skin portion 34 is elastically deformed to the extent that the cross hole 36 is crushed, the electrode wire 38 or the electrode wire 42 becomes the electrode wire 40 or the electrode wire. Conducts by contacting the line 44. When the outer skin portion 34 is restored, the electrode wires 38 to 44 are also restored.

As shown in the circuit diagram of FIG. 6, the electrode wire 38 and the electrode wire 42 are conductive at one longitudinal end, and the electrode wire 40 and the electrode wire 44 are also at one longitudinal end. Conducted in the part. On the other hand, as shown in FIG. 4, a connector 46 is disposed at one end in the longitudinal direction of the outer cover 34. As shown in the circuit diagram of FIG.
6, a resistor 48 is provided. One end of the resistor 48 is electrically connected to the other end of the electrode wire 40 in the longitudinal direction, and the other end of the resistor 48 is electrically connected to the other end of the electrode wire 42 in the longitudinal direction. Wire 40 and electrode wire 42
Are electrically connected via a resistor 48.

In the connector 46, one end in the longitudinal direction of a pair of conducting wires 52 and 54 of a lead wire 50 as a connecting means is accommodated and fixed to a terminal inside the connector 46. The other ends of the above-described electrode wires 38 and 44 in the longitudinal direction are fixed to the terminals to which the conductive wires 52 and 54 are fixed, respectively.
8 are electrically connected, and the conducting wire 54 and the electrode wire 44 are electrically connected. The conducting wire 52 is connected directly to the battery 56 or indirectly via another connecting member (for convenience, the conducting wire 52 and the battery 56 in the circuit diagram of FIG. 6).
And the conducting wire 54 is connected to a battery 56 via a current detecting element 58 which cuts off the circuit when a current of a predetermined value or more flows. That is, from the electrode line 38 to the electrode line 44 via the electrode line 40 and the electrode line 42.
The current flowing to the electrode wire normally flows through the resistor 48, but if the outer skin portion 34 is crushed and the electrode wire 38 or the electrode wire 4
When 2 is brought into contact and short-circuited by contact with the electrode wire 40 or the electrode wire 44, the current flows without passing through the resistor 48. For example, if a current is passed through this circuit at a constant voltage, the current value changes. . Therefore, if a change in the current value at this time is detected, it is determined whether or not the outer skin portion 34 has been crushed, that is,
It can be detected whether or not an external force has acted on the outer cover 34.

As shown in FIG. 6, the current detecting element 58 is connected to the computer 60. When the current detecting element 58 has passed a current of a predetermined value or more in the circuit, that is, the electrode wire 38 or When the current detection element 58 detects that the electrode wire 42 is in contact with the electrode wire 40 or the electrode wire 44 and is conductive and short-circuited, the computer 60 operates the driver 64 of the window regulator 62 to move the window glass 14 up and down. The motor 66 of the window regulator 62 is reversely driven (see FIG. 7).

As shown in FIG. 3, the pressure-sensitive sensor 30 has a long protector 70 as a holding means along the longitudinal direction of the sensor main body 32. Protector 7
Reference numeral 0 denotes a low-rigidity portion 72 made of a synthetic resin material or a rubber material having a lower rigidity than the synthetic resin material forming the outer skin portion 34.
And a high-rigidity portion 74 formed of a synthetic resin material or a rubber material having a higher rigidity than the synthetic resin material forming the outer skin portion 34.
And a holding section 76 constituted by the above. The low rigidity portion 72 is located on the lower side of the vehicle than the high rigidity portion 74,
Basically, it covers most of the outer skin portion 34 (sensor main body 32).

On the other hand, the high-rigidity portion 74 is in contact with the upper portion of the outer peripheral portion of the sensor main body 32 on the vehicle. The sensor body 32 is supported above. This prevents the outer skin portion 34 from being displaced upward without being elastically deformed when an external force from substantially below the vehicle acts on the outer skin portion 34.

The high rigidity portion 74 is formed with a pair of holding legs 78 as holding portions. The holding leg 78 extends substantially upward of the vehicle, and holds the above-described sensor support portion 20 with its own elastic force. Further, engaging projections 80 are formed on the surfaces of the holding legs 78 on the sides facing each other,
The engagement protrusion 80 enters the engagement concave portion 82 formed in the sensor support portion 20 corresponding to the engagement protrusion 80, thereby preventing the protector 70 from being unintentionally detached from the sensor support portion 20. .

However, as shown in FIG.
Protector 70 corresponding to the vicinity of the substantially front end of vehicle 4
In the vicinity of one end of the protector 70, the holding leg 78 is not formed, and the garnish 18 where the vicinity of one end of the protector 70 in the longitudinal direction is located has the sensor support portion 20 formed near the end near the front side of the vehicle. Not. The garnish 18 has a through hole 90 formed substantially near the front end of the vehicle. The through hole 90 is sufficiently larger than the cross-sectional shape of the protector 70 at one end in the longitudinal direction.
The reference numeral 0 penetrates the through hole 90 and is drawn into the sensor terminal accommodating portion 100 on the back surface side of the garnish 18.

Further, in the sensor terminal housing portion 100 on the back side of the garnish 18, the above-described lead wire 50 is routed, and the lead wire 50 is connected to the inside of the door panel 12 from a position very close to a connection portion between the vehicle body and the door panel 12. (That is, between the outer panel and the inner panel) and is electrically connected to the current detection element 58 and the window regulator 62 arranged inside the door panel 12.

Here, as shown in FIG. 2, a grommet 92 is attached to one longitudinal end of the protector 70. The grommet 92 is entirely formed of a rubber material or a synthetic resin material having a predetermined elasticity. The grommet 92 has a small-diameter portion 94 whose outer shape is substantially equal to the inner shape of the through-hole 90, and the small-diameter portion 94 is fitted in a state where the outer peripheral portion is in close contact with the inner peripheral portion of the through-hole 90. The dimension of the small diameter portion 94 along the axial direction (opening direction) of the through hole 90 is equal to the thickness of the garnish 18, that is, the axial size (opening size) of the through hole 90, or the garnish 1.
8 is slightly shorter than the thickness of 8. At both ends of the small-diameter portion 94, large-diameter portions 96 having an inner diameter of the through hole 90 and an outer diameter larger than the connector 46 described above are formed. As described above, the dimension of the small-diameter portion 94 along the axial direction (opening direction) of the through hole 90 is equal to or slightly shorter than the thickness of the garnish 18.
One large diameter portion 96 is in close contact with one surface in the thickness direction of the garnish 18, and the other large diameter portion 96 is in close contact with the other surface in the thickness direction of the garnish 18.

A through hole 98 is formed in the grommet 92 having the above configuration. The through hole 98 is formed so as to penetrate from one large diameter portion 96 to the other large diameter portion 96 via the small diameter portion 94, and has an inner peripheral shape which is one end side of the protector 70 in the longitudinal direction (that is, the holding leg 78). ), One end in the longitudinal direction of the protector 70 passes through the through hole 98, and the inner peripheral portion of the through hole 98 is in close contact with the outer peripheral portion of the protector 70.

<Operation and Effect of First Embodiment>
The operation and effect of the present embodiment will be described.

When the window glass 14 is stored inside the door panel 12 (ie, between the inner panel and the outer panel constituting the door panel 12), a switch (not shown) provided on the vehicle interior side or the like is operated. When the driver 66 of the window regulator 62 is operated to rotate the motor 66 in the normal direction, the window glass 14 moves upward by the driving force of the motor 66. Basically, the window glass 14 that has moved up moves until the upper end abuts on the weather strip 16 so that the door panel 1 is moved by the window glass 14.
Then, the space between the upper end portion 2 and the weather strip 16 is closed and stopped.

In the case where foreign matter is present above the ascending window glass 14, the upper end of the window glass 14 contacts the foreign matter before contacting the weather strip 16, and the window glass 14 Is pressed upward to move the foreign matter upward to approach the weather strip 16 and the garnish 18.

Foreign matter approaching the garnish 18 comes into contact with the protector 70 of the pressure-sensitive sensor 30 located substantially below the vehicle with respect to the weather strip 16 before abutting on the weather strip 16 to cause the protector 70 to contact the garnish 18. Press upward. The holding portion 76 of the protector 70 has a low rigidity portion 7.
2 and the high-rigidity portion 74, but as described above,
Since the low-rigidity portion 72 is located on the lower side of the vehicle than the high-rigidity portion 74, the foreign matter elastically deforms the low-rigidity portion 72 having relatively low rigidity. Here, the rigidity of the low rigidity portion 72 is
4, the pressing force from the foreign material is immediately transmitted to the outer skin portion 34 without being impeded by the low rigidity portion 72, and the outer skin portion 34 is transmitted through the low rigidity portion 72. It is crushed (elastically deformed) by the pressing force from the received foreign matter.

Since the stiffness is higher than the outer skin portion 34 above the outer skin portion 34, the high-rigidity portion 74 is not elastically deformed together with the outer skin portion 34 subjected to the pressing force from the foreign matter. Therefore, the outer cover 34 receiving the pressing force from the foreign matter does not move upward without elastic deformation.

When the outer skin 34 is crushed, the outer skin 3
When the electrode wire 38 or the electrode wire 42 inside the electrode 4 comes into contact with the electrode wire 40 or the electrode wire 44 to be short-circuited, the current flows without passing through the resistor 48. Thus, for example, if a current is applied to the electric circuit including the electrode lines 38 to 44 at a constant voltage, the current value changes, and the change in the current value at this time is detected by the current detection element 58.

When the computer 60 receives an electric signal from the current detecting element 58 when the change in the current value is detected, the computer 60 changes the current value, that is, the outer cover 34 is pressed by the foreign object. It is determined that the electrode wire 38 or the electrode wire 42 is crushed and comes into contact with the electrode wire 40 or the electrode wire 44 to conduct electricity.

The computer 60 having made the above determination operates the driver 64 of the window regulator 62 to invert the motor 66 of the window regulator 62. As a result, the window glass 14 descends to release the foreign matter from being caught.

In the power window device 10, the sensor body 32 of the pressure-sensitive sensor 30 is not embedded in the weather strip 16 but is covered by a protector 70, and the protector 70 is formed on the garnish 18. It is supported by the support part 20. Thus, even if the upper end of the window glass 14 is pressed against the weather strip 16, the pressure sensor 30 is not affected at all. For this reason, even if the weather strip 16 is deformed, there is no erroneous recognition that the pressure-sensitive sensor 30 has caught foreign matter.

Further, an insertion hole for inserting the sensor main body 32 into the weather strip 16 is formed to form the sensor main body 32.
In this embodiment, since it is only necessary to hold the holding leg 78 of the protector 70 on the sensor support portion 20 of the garnish 18, the assembly of the pressure-sensitive sensor 30 is improved. Man-hours are reduced.

Further, when an insertion hole for inserting the sensor main body 32 into the weather strip 16 is formed, the inner diameter of the insertion hole must not be too large or too small than the outer diameter of the sensor main body 32. Therefore, dimensional control is difficult, and strict dimensional control must be performed over the entire insertion hole along the axial direction. However, in the present embodiment, there is an error in the dimensions of the holding leg 78 and the sensor support portion 20. This does not affect the detection performance of the pressure sensor 30.

On the other hand, in the present embodiment, the garnish 18 does not support the protector 70 with the sensor supporting portion 20 near the end of the garnish 18 substantially on the front side of the vehicle.
The garnish 18 does not support the protector 70 with the sensor support 20 near the end of the garnish 18 substantially on the front side of the vehicle. As described above, the grommet 92 is attached to the through hole 90 formed in the garnish 18 near the end of the garnish 18 substantially on the front side of the vehicle, and the protector 70 penetrates the through hole 98 of the grommet 92 so that the garnish 18 Is drawn into the sensor terminal accommodating section 100 on the back side of the sensor terminal. The connector 46 for connecting one end in the longitudinal direction of the electrode wires 38 to 44 of the sensor main body 32 is disposed on the back side of the garnish 18, so that the connector 4
6 and the lead wire 50 cannot be seen from inside and outside the vehicle interior,
The appearance (design) of the vehicle is not deteriorated.

Further, since the through hole 90 of the garnish 18 is closed by the grommet 92, the through hole 90 itself cannot be basically seen, and in this sense, the appearance (design) of the vehicle does not deteriorate.

Further, in the present embodiment,
Although the connector 46 and the lead wire 50 are treated so as to be invisible from the inside and outside of the vehicle, the work for that purpose is performed together with the grommet 92 through the through hole 90 formed in the garnish 18 with the protector 70 (pressure-sensitive sensor 30). , The workability for performing the above processing is extremely good.

Further, since the connector 46 and the lead wire 50 are arranged in the sensor terminal accommodating portion 100 on the back surface of the garnish 18 and the gap between the through hole 90 and the protector 70 is closed by the grommet 92, rainwater or the like is removed. 46 and the vicinity of the lead wire 50, and the pressure-sensitive sensor 30 caused by rainwater, foreign matter, etc. adhering to the connector 46.
Can be reduced or prevented from deteriorating the detection performance.

In this embodiment, the grommet 92 is used.
Is fitted in the through hole 90, but the closing member capable of closing the gap between the through hole 90 and the protector 70 is not limited to the grommet 92. For example, the through hole 90
A configuration may be adopted in which an adhesive, a putty, or the like is provided between the protector 70 and the through hole 90 to close the space between the through hole 90 and the protector 70.

<Structure of the Second Embodiment> Next, another embodiment of the present invention will be described. Each of the following embodiments is basically the same as the protector 70 and the sensor support 20 of the garnish 18 in the first embodiment.
This is a modified example. Further, in the following description of each embodiment, the same reference numerals are used for parts that are basically the same as the above-described embodiment than the embodiment described including the first embodiment. And description thereof is omitted.

FIG. 8 is a sectional view showing a configuration of a main part of a power window device 120 as an automatic opening / closing device according to a second embodiment of the present invention. As shown in this drawing, the pressure-sensitive sensor 122 of the power window device 120 includes a protector 124 as holding means. The high-rigidity portion 126 of the protector 124 is basically the same as the high-rigidity portion 74 of the protector 70 in the first embodiment, but an auxiliary fitting 128 having a higher rigidity than the high-rigidity portion 126 is provided inside the protector. It is embedded continuously or intermittently along the longitudinal direction of the reference numeral 124.

The auxiliary fitting 128 has a plate-like base 130 extending in the width direction substantially along the left-right direction of the vehicle, and leg portions 132 extending from both ends in the width direction of the base 130 substantially toward the upper side of the vehicle. The overall cross-sectional shape is a substantially concave shape that opens substantially toward the upper side of the vehicle. Each of the legs 132 corresponds to each of the holding legs 78 of the high rigidity portion 126, and is embedded inside each of the holding legs 78.

<Operation and Effect of Second Embodiment> The present embodiment having the above-described configuration will be compared with the first embodiment. Assuming that the rigidity of the high-rigidity portion 126 excluding the auxiliary metal fitting 128 is the same as the rigidity of the high-rigidity part 74 in the first embodiment, the high-rigidity part 126 has
Is embedded, the rigidity of the high-rigidity part 126 is improved.
That is, the rigidity of the holding leg 78 is improved by embedding the leg 132 of the auxiliary fitting 128 inside each holding leg 78, and when the holding leg 78 holds the sensor support unit 20, the two holding legs 78 are held. Are less likely to deform in the direction away from each other. Thus, the protector 70 (the pressure-sensitive sensor 30) can be supported by the sensor support 20 for a long time.

<Structure of Third Embodiment> FIG. 9 is a sectional view showing the structure of a main part of a power window device 140 as an automatic opening / closing device according to a third embodiment of the present invention. I have. As shown in this drawing, in the pressure-sensitive sensor 142 of the power window device 140, a groove 148 that opens substantially toward the vehicle width direction inside the vehicle is formed in the high-rigidity portion 146 of the protector 144 as a holding unit. The inner walls of the groove 148 facing each other inside the groove
This corresponds to the holding leg 78 in the first embodiment.

The sensor support 150 of the garnish 18 extends substantially outward in the vehicle width direction, unlike the sensor support 20 of the first embodiment, corresponding to the protector 144 described above.

The sensor support 150 is a high rigidity part 146.
The inner walls opposing each other inside the groove 148 sandwich the sensor support 150 by entering the groove 148, whereby the protector 144 is supported by the sensor support 150.

<Operation and Effect of Third Embodiment> As described above, in the present embodiment, since the sensor support portion 150 is inserted into the groove portion 148 opened toward the indoor side in the vehicle width direction, the gravitational action is performed. The direction is different from the direction in which the protector 144 drops off from the sensor support 150.
Therefore, even if the inner wall of the groove 148 does not pinch the sensor support 150 with a particularly large pinching force, the sensor support 15
0 can support the protector 144.

Further, unlike the sensor support portion 20 in the first embodiment, the sensor support portion 150 is formed so as to extend substantially toward the outside of the vehicle in the vehicle width direction, so that the sensor support portion 150 is formed. In this case, it is not necessary to bend the garnish 18 greatly. For this reason, manufacture of the garnish 18 becomes easy.

<Structure of Fourth Embodiment> FIG.
A cross-sectional view shows a configuration of a main part of a power window device 160 as an automatic opening / closing device according to a second embodiment of the present invention. As shown in this figure, in the pressure-sensitive sensor 162 of the power window device 160, a groove 148 that opens substantially toward the vehicle width direction inside the vehicle is formed in the high-rigidity portion 166 of the protector 164 as a holding unit. An auxiliary fitting 168 having a higher rigidity than the high-rigidity portion 166 is embedded continuously or intermittently along the longitudinal direction of the protector 164. Auxiliary fitting 1
Reference numeral 68 denotes a plate-like base portion 170 extending in the width direction substantially along the vehicle vertical direction, and leg portions 172 extending from both ends in the width direction of the base portion 130 substantially toward the vehicle width direction indoor side. The overall cross-sectional shape is a substantially concave shape that opens substantially toward the interior side in the vehicle width direction. Each leg 172
Correspond to inner walls facing each other inside each groove 148 of the high rigidity portion 166.

<Operation and Effect of Fourth Embodiment> As described above, the present embodiment is a configuration having both the configuration of the second embodiment and the third embodiment described above. Both the operations described in the second embodiment and the third embodiment can be performed, and both effects can be obtained.
