FIG. 3D is a cross-sectional view showing a state in which the finger F is in contact with the contact sensor 3 in the cross section taken along line BB in FIG.

The contact sensor 3 includes a contact member 31 that elastically deforms upon contact with a contact object, a holding member 32 that holds the contact member 31, a contact detection unit 33 that outputs contact with the contact object as an electric signal, and a holding member 32. And a flat mount member 34 interposed between the contact detection unit 33 and the upper end surface 10a of the door glass 10.

The contact member 31 is made of a flexible material such as rubber and is elastically deformed by contact with a contact object. The holding member 32 is made of a material having a higher elastic modulus than that of the contact member 31. For example, polycarbonate, acrylic, polyacetal, or the like can be suitably used. Here, the elastic modulus is a value obtained by dividing the stress by the strain within the elastic limit, and indicates that the higher the value, the harder the material is to be deformed.

The holding member 32 is fixed to the door glass 10 via the mount member 34. The mounting member 34 has an upper surface 34 a bonded to the holding member 32 and the contact detection unit 33, and a lower surface 34 b bonded to the upper end surface 10 a of the door glass 10.

And a plurality of window portions 320 to be inserted. Each window part 320 is a long hole extending along the longitudinal direction of the contact sensor 3 in a top view shown in FIG. 3A, and is partitioned by a beam part 322 formed integrally with the wall part 321. In FIG. 3A, the outer edge of the window part 320 is shown with the broken line.

The contact detection unit 33 is disposed in parallel with the first conductive member 331 disposed along the longitudinal direction of the upper end surface 10 a of the door glass 10, and the first conductive member 331, and more than the first conductive member 331. A second conductive member 332 having a large resistance value per unit length, and a pair of separation members 333 that separate the first conductive member 331 and the second conductive member 332 so as to be able to contact and separate are provided. The first conductive member 331 and the second conductive member 332 are pressed and contacted by the contact member 31 at the contact position between the contact member 31 and the contact object. The second conductive member 332 is an electric resistor having a predetermined resistivity made of, for example, conductive rubber, and has a uniform resistance value per unit length in the longitudinal direction.

The second conductive member 332 is fixed to the upper surface 34a of the mount member 34 by a fixing means such as adhesion. The mount member 34 is made of the same resin material as the holding member 32, for example. The first conductive member 331 is made of a highly conductive metal such as aluminum or copper, for example, and is arranged in parallel with the second conductive member 332.

The contact member 31 includes a pressing portion 311 that presses the contact detection portion 33 through the window portion 320 formed in the holding member 32, and the opposite side of the contact detection portion 33 from the window portion 320 (more than the window portion 320. And a contact portion 312 that comes into contact with the contact object on the upper side. Then, as shown in FIG. 3D, when the contact object (finger F) comes into contact with the upper surface 312a of the contact portion 312 and the contact portion 312 is pushed downward by the contact pressure and elastically deformed, the pressing portion 311 becomes the window portion. The first conductive member 331 of the contact detection unit 33 is pressed downward from 320 and is brought into contact with the second conductive member 332.

FIG. 4 is a perspective view showing a connection state between the contact sensor 3 and the cable 5 at the front end portion of the door glass 10. 5A to 5C and FIGS. 6A and 6B are explanatory diagrams showing the configuration and operation of the contact detection unit 33 in the control device 4 and the contact sensor 3. FIG.

The control device 4 and the contact sensor 3 are connected by first to third electric wires 51 to 53 of the cable 5. The first to third electric wires 51 to 53 are covered with a sheath 50 as shown in FIG. The sheath 50 and the first to third electric wires 51 to 53 constitute the cable 5. The first to third electric wires 51 to 53 are insulated electric wires in which a core wire made of a conductive wire such as copper is covered with an insulator made of resin, rubber or the like. Although not shown, the end portion of the contact sensor 3 is sealed with silicon resin or the like, so that intrusion of water or the like between the contact detection unit 33 or the contact member 31 and the holding member 32 is suppressed. Yes.

For example, as illustrated in FIG. 5A, the control device 4 includes a CPU 40 that is an arithmetic element, a storage element 41 that stores a program executed by the CPU 40, a DC power source 42, and a current that measures an output current from the DC power source 42. It has a total 43, first to third switching elements 44 to 46, and a current output unit 47 that supplies a motor current to the electric motor 24.

The CPU 40 can detect the current output from the DC power supply 42 by receiving the detection signal from the ammeter 43. Further, the CPU 40 can output a command signal to the current output unit 47 to cause the electric motor 24 to rotate forward and backward. That is, the CPU 40 functions as a control unit that controls the window regulator 2.

The first to third switching elements 44 to 46 are turned on or off by the CPU 40. In the present embodiment, the first to third switching elements 44 to 46 are transistors, but elements such as FETs and solid state relays can also be used. In the following description, the state in which current can flow through the first to third switching elements 44 to 46 is set to the on state, and the state in which the first to third switching elements 44 to 46 block the current is the off state. And

In the following description, the end of the second conductive member 332 connected to the second electric wire 52 on the vehicle front side is point A, and the first conductive member 331 connected to the first electric wire 51 is a vehicle. A front end is a point B, and a rear end of the second conductive member 332 connected to the third electric wire 53 is a C point. In addition, the vehicle rear side end portion of the first conductive member 331 is an open end, and is not electrically connected to any member.

The CPU 40 can change the path of the current output from the DC power source 42 by switching the on / off states of the first to third switching elements 44 to 46.

Specifically, by turning on the third switching element 46 and turning off the first switching element 44 and the second switching element 45, the current output from the DC power source 42 as shown in FIG. 5A. Can flow from point A to point C. Further, the CPU 40 turns on the second switching element 45 and turns off the first switching element 44 and the third switching element 46, thereby changing the current output from the DC power source 42 from the point A to the point B. Can flow (see FIG. 6A). Further, the CPU 40 turns on the first switching element 44 and the third switching element 46 and turns off the second switching element 45, thereby changing the current output from the DC power supply 42 from the point B to the point C. (See FIG. 6B).

Based on the current value detected by the ammeter 43 in each of these states, the CPU 40 is between points A and C, between points A and B, and between points B and C. It is possible to detect the electrical resistance in the current path.

When the current output from the DC power supply 42 flows through the second conductive member 332 from the point A to the point C, as shown in FIG. The first conductive member 331 and the second conductive member 332 are in contact with each other over the contact length L _P between the end portion P _{1 on} the vehicle front side and the end portion P ₂ on the rear side of the vehicle.

At this contact point P, current flows through the first conductive member 331 having a low resistance value, and the electrical resistance in the current path from point A to point C decreases. Thereby, since the current flowing through the ammeter 43 increases, the CPU 40 can detect that the contact object has come into contact with the contact sensor 3 based on the change in the current value, and the contact length at the contact point P. it is possible to detect the L _P.

Further, as shown in FIG. 5C, the contact product is contacted portion _P A, in contact with the contact sensor 3 at two points of _{P B,} both contact point _P A, the first conductive member 331 in the _{P B} second conductive The member 332 comes into contact. _A current flows through the first conductive member 331 between the contact location PA and the contact location P _B, and the current detected by the ammeter 43 further increases.

When the contact object contacts the contact sensor 3 at one contact point P as shown in FIG. 5B, the CPU 40 switches the on / off states of the first to third switching elements 44 to 46 and outputs them from the DC power source 42. by changing the path of the current, it is possible to detect the position of the end portion P ₁ and the end portion P ₂ of the vehicle rear side of the vehicle front side of the contact point P.

Specifically, as shown in FIG. 6A, the second switching element 45 is turned on, the first switching element 44 and the third switching element 46 are turned off, and a current flows from point A to point B. , current introduced to the point a is folded at the end portion P ₁ of the vehicle front side of the contact point P, flowing through the B point. In this case, since the electrical resistance between the point A and the point B is proportional to the distance between the point A and the contact point P (end portion P ₁ ), the CPU 40 has an end portion on the vehicle front side of the contact point P. the position of P ₁ can be obtained by calculation.

Further, as shown in FIG. 6B, the first switching element 44 and the third switching element 46 are turned on, the second switching element 45 is turned off, and a current is passed from the point B to the point C. introduced current flows through the second conductive member 332 between the end portion P ₂ and the point C of the vehicle rear side of the contact point P on. In this case, since the electrical resistance between the point B and the point C is proportional to the distance between the contact point P (end portion P ₂ ) and the point C, the CPU 40 detects the end of the contact point P on the vehicle rear side. position parts P ₂ can be determined by calculation.

Thus, the CPU 40 can detect the contact position between the contact sensor 3 and the contact object based on the signal (current signal) from the contact sensor 3. CPU40 by measuring the resistance value in the current path between the points A and B is equal to that for detecting the position of the end P ₁ of the vehicle front side of the contact points P, between the points B and C Measuring the resistance value in the current path is equivalent to detecting the position of the end portion P ₂ on the vehicle rear side of the contact point P. Further, measuring the resistance value in the current path between the points A and C is equivalent to detecting the contact length L _P at the contact point P.

The currents flowing through the first to third electric wires 51 to 53 are detection signals indicating the contact state between the contact sensor 3 and the contact object. The CPU 40 controls the window regulator 2 based on the detection signal of the contact sensor 3.

7A to 7D schematically show a simplified model of the door 1 and are explanatory diagrams showing movement instructions to the vehicle door glass opening and closing device 100 according to the present embodiment.

When the door glass 10 is stopped, the CPU 40 can accept an instruction to move the door glass 10 in the vertical direction by a user through a contact operation on the contact sensor 3. More specifically, the CPU 40 can discriminate between a rising instruction for raising the door glass 10 and a lowering instruction for lowering the door glass 10 based on the detection signal of the contact sensor 3 when the contact operation is performed. .

Further, the CPU 40 determines an ascending instruction and a descending instruction according to the contact position in the contact sensor 3 when the contact operation is performed. In the present embodiment, the detection signal when the contact operation is performed on the contact sensor 3 in the range arranged on the inclined portion 10B of the door glass 10 is determined to be a lowering instruction, and the detection signal is arranged on the flat portion 10A of the door glass 10. The detection signal when touching the contact sensor 3 in the specified range is determined as an ascending instruction.

As shown in FIG. 7A, when the user's finger F touches one place (point X shown in the drawing) in the range where the user's finger F is arranged on the inclined portion 10 </ b> B of the door glass 10, the CPU 40 Accordingly, it is recognized that a movement instruction has been made based on the detection signal of the contact sensor 3, and the movement instruction is determined to be a lowering instruction based on the detected contact position. Then, the CPU 40 outputs a command signal to the electric motor 24 to the current output unit 47 so that the door glass 10 is lowered. As a result, the door glass 10 moves to the lower end in the downward direction indicated by the downward arrow in FIG. 7B. Thereby, the window part 1a will be in a fully open state. The CPU 40 can detect the contact position based on the detection signal of the contact sensor 3 when the contact operation is performed based on the principle described in FIGS. 6A and 6B.

On the other hand, as shown in FIG. 7C, when the user's finger F touches one place (Y point shown in the figure) in the range where the user's finger F is arranged on the flat portion 10 </ b> A of the door glass 10, the CPU 40 It is recognized that a movement instruction has been made based on the detection signal of the contact sensor 3 accompanying this contact, and the movement instruction is determined to be an ascending instruction based on the detected contact position. Then, the CPU 40 outputs a command signal to the electric motor 24 so as to raise the door glass 10 to the current output unit 47. As a result, the door glass 10 moves to the rising end in the upward direction indicated by the upward arrow in FIG. 7D. Thereby, the window part 1a will be in a fully closed state.

At this time, the CPU 40 sets the current output unit so that the electric motor 24 is normally driven after a predetermined time (for example, 1 second) has elapsed since the contact state in which the user's finger F touches the contact sensor 3 is released. A command signal is output to 47. That is, when it is determined that there is an ascent instruction, the CPU 40 controls the electric motor 24 so that the door glass 10 ascends after a predetermined time elapses after the finger F leaves the contact sensor 3.

Thus, if the door glass 10 rises immediately after the user performs a contact operation with the finger F, the door glass 10 rises before the contact state between the finger F and the contact sensor 3 is released, and the door sash 11 There is a possibility that the finger F is sandwiched between the contact sensor 3 and the contact sensor 3, but in this embodiment, such a situation can be prevented.

According to the vehicle door glass opening and closing device 100 described above, the door glass 10 can be opened and closed simply by performing a contact operation on the contact sensor 3 disposed on the upper surface of the door glass 10. The operability of the opening / closing operation is improved. Further, for example, as compared with the case where a plurality of contact sensors are disposed as in the apparatus described in Patent Document 2, it is only necessary to dispose a single contact sensor 3, so that an increase in manufacturing cost can be suppressed.

In the present embodiment, the movement instruction when the contact operation is performed on the contact sensor 3 in the range disposed on the inclined portion 10B of the door glass 10 is determined as the descending instruction, and the contact in the range disposed on the flat portion 10A. Although the case where the movement instruction when the contact operation is performed on the sensor 3 is determined as the ascending instruction has been described, the present invention is not limited to this. For example, you may limit a contact position to the range arrange | positioned at 10 A of flat parts. More specifically, when the user's finger F comes into contact with the front side of the vehicle in the extending direction of the contact sensor 3 in the range arranged on the flat portion 10A of the door glass 10, the CPU 40 determines that the instruction is ascending, and the vehicle When the finger F comes in contact with the rear side, the CPU 40 may determine that the instruction is a lowering instruction.

[Variation 1 of the first embodiment]
Next, Modification 1 according to the first embodiment will be described with reference to FIGS. 8A to 8D. FIG. 8A to FIG. 8D schematically show a simplified model of the door 1, and are explanatory diagrams showing a movement instruction to the vehicle door glass opening / closing device 100 according to this modification.

8A to 8D, members or portions having functions substantially common to the components described in the first embodiment are denoted by the same reference numerals, and redundant description thereof is omitted.

In this modification, unlike the first embodiment, the condition for determining whether the movement instruction by the user is an ascending instruction or a descending instruction is different from that in the first embodiment. An ascending instruction and a descending instruction are discriminated according to the length between the points. In the present modification, for example, when the length between the detected operation start point and the operation end point is equal to or greater than a predetermined value, it is determined that the instruction is a lowering instruction. Is determined.

As shown in FIG. 8A, when the user performs a slide operation in the direction of the arrow in the figure with the finger F in contact with the contact sensor 3, the CPU 40 generates a detection signal from the contact sensor 3 along with the contact operation. Based on this, it is recognized that a movement instruction has been made, and the length between the operation start point (S point shown in the figure) and the operation end point (T point shown in the figure) is equal to or greater than a predetermined value. It detects and discriminates the movement instruction from the lowering instruction. Then, the CPU 40 outputs a command signal to the electric motor 24 to the current output unit 47 so that the door glass 10 is lowered. As a result, the door glass 10 moves to the lower end in the downward direction indicated by the downward arrow in FIG. 8B. Thereby, the window part 1a will be in a fully open state.

On the other hand, as shown in FIG. 8C, when the user slides the finger F in contact with the contact sensor 3 in the direction of the arrow in the figure, the CPU 40 detects the detection signal of the contact sensor 3 along with this contact operation. Based on this, it is recognized that the movement instruction has been made, and the length between the operation start point (S point shown in the figure) and the operation end point (T point shown in the figure) is less than a predetermined value. Detecting and distinguishing the movement instruction from the ascending instruction. Then, the CPU 40 outputs a command signal to the electric motor 24 so as to raise the door glass 10 to the current output unit 47. As a result, the door glass 10 moves to the rising end in the upward direction indicated by the upward arrow in FIG. 8D. Thereby, the window part 1a will be in a fully closed state. The sliding direction is not limited. For example, the same control as described above may be performed by sliding the T point shown in the figure as the operation start point and the S point shown in the figure as the operation end point. Good.

According to this modified example configured as described above, the door glass 10 can be moved up and down regardless of the position of contact with the contact sensor 3.

[Modification 2 of the first embodiment]
Next, Modification 2 according to the first embodiment will be described.

In the present modification, the condition for determining whether the movement instruction by the user is an ascending instruction or a descending instruction is different from the first embodiment, depending on the number of times the user contacts the contact sensor 3 within a predetermined time. An ascending instruction and a descending instruction are determined.

In this modification, for example, when the number of times of contact with the contact sensor 3 by the user's finger F within a predetermined time (for example, 0.5 seconds) is a predetermined number (for example, once), the CPU 40 instructs the movement instruction to increase. When the number of times of contact with the contact sensor 3 exceeds a predetermined number (for example, when the number of times of contact is two or more), it is determined that the movement instruction is a lowering instruction. That is, the CPU 40 counts the number of times the finger F contacts the contact sensor 3 based on the detection signal of the contact sensor 3 within a predetermined time, and determines an ascending instruction and a descending instruction according to the contact state.

The relationship between the number of contacts and the determination result is not limited to this. For example, when the number of contacts within a predetermined time is one, the instruction is determined to be a lowering instruction, and when it is two or more times, the instruction is determined to be an increasing instruction. The CPU 40 may be configured to do so.

[Modification 3 of the first embodiment]
Next, Modification 3 according to the first embodiment will be described.

In this modification, unlike the first embodiment, the condition for determining whether the movement instruction by the user is an ascending instruction or a descending instruction is increased according to the length of the contact time of the user with the contact sensor 3. An instruction and a descending instruction are discriminated.

In this modification, for example, the CPU 40 has a predetermined contact time between the finger F and the contact sensor 3 (a time during which the contact state between the finger F and the contact sensor 3 continues) based on a detection signal obtained by a user's contact operation. If it is less than the time (for example, 2 seconds), it is determined as a descending instruction. The relationship between the contact time and the movement instruction is not limited to this. For example, when the contact time is less than a predetermined time, it is determined as an ascending instruction, and when it is longer than the predetermined time, it is determined as a descending instruction. The CPU 40 may be configured.

According to this modified example configured as described above, the operability is improved similarly to the modified examples 1 and 2 according to the first embodiment.

[Modification 4 of the first embodiment]
Next, Modification 4 according to the first embodiment will be described.

In this modification, the condition for determining whether the movement instruction by the user is an ascending instruction or a descending instruction is different from the first embodiment, and the number of times of contact with the contact sensor 3 within a predetermined time is a plurality of times. An ascending instruction and a descending instruction are discriminated according to the change in the contact position.

In this modification, for example, when the user performs a contact touch operation for each finger with the plurality of fingers F on the contact sensor 3, the CPU 40 determines the contact position based on a detection signal obtained by the user's contact operation. If the contact position is continuously moving from the vehicle front side to the vehicle rear side in the longitudinal direction of the contact sensor 3, the movement instruction is determined as an ascending instruction, and the contact position is determined by the contact sensor 3. When the vehicle moves continuously from the vehicle rear side to the vehicle front side in the longitudinal direction, the movement instruction is determined as a lowering instruction. At this time, the CPU 40 may be configured to increase or decrease the moving speed of the door glass 10.

According to this modified example configured as described above, since the user can instruct the movement of the contact sensor 3 by an intuitive contact operation, for example, when the user performs a contact operation on the contact sensor 3 a plurality of times. Thus, it is possible to prevent malfunction when a contact operation is performed at the same position of the contact sensor 3 against the user's intention.

The rising instruction and the lowering instruction are discriminated according to the length of the contact range between the first conductive member 332 and the second conductive member 332. That is, the CPU 40 determines an ascending instruction and a descending instruction according to the pressing force in the contact operation.

In the present modification, for example, the CPU 40 detects the length of the contact range between the first conductive member 331 and the second conductive member 332 that has been changed by the pressing force based on a detection signal generated by the user's contact operation. When the length of the contact range is equal to or greater than a predetermined value, the movement instruction is determined as an ascending instruction, and when the length of the contact range is less than the predetermined value, it is determined as a descending instruction. At this time, the CPU 40 may be configured to increase or decrease the moving speed of the door glass 10. The method for determining the movement instruction based on the predetermined value is not limited to this. For example, it is determined that the movement instruction is a lowering instruction when it is equal to or greater than the predetermined value, and is determined as an ascending instruction when it is less than the predetermined value. Also good.

According to the present modification configured as described above, the operability is improved as in the first to third modifications according to the first embodiment.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS. 9A to 9D. FIG. 9A to FIG. 9D schematically show a simplified model of the door 1, and are explanatory diagrams showing movement instructions to the vehicle door glass opening / closing device 100 according to the present embodiment.

9A to 9D, members or portions having functions substantially common to the components described in the first embodiment are denoted by the same reference numerals, and redundant description thereof is omitted.

In 1st Embodiment, when the movement instruction | indication of the door glass 10 was made, the case where the door glass 10 was moved to a raise end or a descent | fall end was demonstrated, However, in 2nd Embodiment, the moving amount | distance of the door glass 10 further. Is adjustable. That is, in the second embodiment, the CPU 40 increases or decreases the amount of movement of the door glass 10 according to the position of the user touching the contact sensor 3.

As shown in FIG. 9A, when the user touches one place (Z point shown in the drawing) of the contact sensor 3 in the range where the user F is placed on the inclined portion 10B of the door glass 10, the CPU 40 As in the embodiment, it is recognized that a movement instruction has been made based on the detection signal of the contact sensor 3 accompanying this contact operation, and the movement instruction is determined to be a lowering instruction based on the detected contact position. At this time, the CPU 40 detects the contact position (Z point) of contact with the contact sensor 3 of the finger F based on the detection signal, and the contact position (Z point) is the seal lip of the weather strip 15 as shown in FIG. 9B. The door glass 10 is controlled to descend until it comes into contact with the vehicle interior seal lip 151 and the vehicle exterior seal lip 156.

Similarly, as shown in FIG. 9C, when the user touches one place (point W shown in the drawing) of the contact sensor 3 in the range where the user F is placed on the inclined portion 10B of the door glass 10, the CPU 40 Based on the detection signal of the contact sensor 3, it is recognized that a movement instruction has been made, and the movement instruction is determined to be a lowering instruction based on the detected contact position. At this time, as shown in FIG. 9D, the CPU 40 lowers the door glass 10 until the contact position (point W) comes into contact with the seal lips (the vehicle interior seal lip 151 and the vehicle exterior seal lip 156) of the weather strip 15. To control.

Thus, in the present embodiment, the amount of movement of the door glass 10 can be increased or decreased according to the contact position with the user's finger F. That is, the user can move the door glass 10 to a desired position by touching the door glass 10 with fingers F. Thereby, in addition to the effect | action and effect similar to 1st Embodiment, the movement precision of the door glass 10 can be improved.

In addition, although this embodiment demonstrated only the case where the door glass 10 was moved until a contact position contacted the seal lip of the weather strip 15, it is not limited to this. For example, the door glass 10 may be moved based on a movement amount set in advance according to the contact position. Specifically, when the first to third contact areas are provided in order from the front of the vehicle to the rear of the vehicle in the extending direction of the contact sensor 3, and the user's finger F comes into contact with the first contact area The distance of movement may be set in advance, such as 50 mm, 200 mm when the second contact area is touched, and fully open when the third contact area is touched.

Furthermore, the function of controlling the amount of movement of the door glass 10 in the present embodiment can be variously applied not only to the first embodiment but also to the first, second, and third modifications according to the first embodiment. . For example, the CPU 40 may determine whether it is an ascending instruction or a descending instruction according to the number of times of contact, and may further increase or decrease the amount of movement of the door glass 10 according to the contact position.

[Modification of Second Embodiment]
Next, a modification according to the second embodiment will be described.

In this modification, the method for increasing or decreasing the amount of movement of the door glass 10 is different from that of the second embodiment. That is, in the second embodiment, the movement amount of the door glass 10 is increased or decreased according to the contact position, whereas in the present modification, the movement amount of the door glass 10 is changed according to the length of the contact range. Increase or decrease.

Here, “the length of the contact range” refers to the distance between both end portions of the contact location. When there are a plurality of contact locations, the contact portion on the most vehicle front side in these contact locations and the most rear side of the vehicle. This is the distance to the contact part on the side. For example, as shown in FIG. 5C, when the contact portion of the contact sensor 3 is two places, the contact points P with the vehicle front end portion P ₃ of _A, the contact point P end P ₄ of the vehicle rear side of the _B The distance between and the “contact range length”.

The CPU 40 according to the present modification detects the length of the contact range based on the principle described with reference to FIGS. 5C, 6A, and 6B when the contact operation to the contact sensor 3 with the user's finger F is performed. Control is performed so that the door glass 10 moves a movement amount set in advance according to the length of the contact range. For example, the threshold value may be set in advance, such as 50 mm when the length of the contact range is smaller than the predetermined threshold value, and 100 mm when larger than the predetermined threshold value. Further, by setting a plurality of threshold values, the movement amount of the door glass 10 can be more finely increased or decreased.

Therefore, when the user performs a contact operation, the length of the contact range is changed by changing the number of fingers F contacting the contact sensor 3 by changing the number of fingers F to two or three instead of one, for example. Therefore, the movement amount of the door glass 10 can be increased or decreased.

According to this modified example configured as described above, in addition to the operation and effect of the second embodiment, the door glass 10 can be simply changed by changing the number of fingers F contacting the contact sensor 3 regardless of the contact position. Since the amount of movement can be increased or decreased, the operability is further improved.

It should be noted that the functions related to this modification described so far can be applied in various ways to the first embodiment and the modifications 2 to 4 according to the first embodiment.
