Description

[Technical field]

[0001] The present invention relates to a vehicle side glass device. [Background technology]

[0002] Generally, when a passenger is carrying baggage and gets into a vehicle, the passenger places the baggage on the passenger seat, the back seat, the trunk, or the like of the vehicle.

[0003] If the rear door of a vehicle is not a sliding door, it may be difficult to fully open the door in a parking lot if other vehicles are parked nearby, and passengers may not be able to place their luggage on the rear seat. Therefore, there is a demand for convenience if passengers' belongings, such as hand luggage, shopping bags, umbrellas, coats, etc., can be placed inside the vehicle through an open window without having to open the door.

[0004] As a technology to meet the above-mentioned requirements, a technology has been disclosed in which a slider slidably fitted into main rails arranged on the upper and lower edges of the side window is attached to the window glass via a flip-out link, a guide of the flip-out link is slidably fitted into a sub-rail arranged on the outside of the main rail, the sub-rail is provided with a bent portion for flipping out the window glass, and the slider is slid by a motor via a wire, thereby further opening the window glass of a side window of a vehicle such as an automobile (see, for example, Patent Document 1).

[0016] <Embodiment> The configuration of a vehicle side glass device 10 according to this embodiment will be described with reference to Figs. A vehicle V to which the vehicle side glass device 10 of this embodiment is applied is assumed to be equipped with a rear door RD having a hinge at the front or rear of the vehicle, and a door that opens by rotating outward in the vehicle width direction around the hinge as the center of rotation when the rear door RD is opened, and the rear door RD is assumed to be in a closed state.

[0017] <Configuration of the Vehicle Side Window Device 10> As shown in FIG. 1, a vehicle side glass device 10 according to this embodiment includes a side glass portion 100, a slide rail portion 200, a synchronization portion 300, and a connection portion 400. The side glass portion 100 includes a side glass unit 100, a slide rail portion 200, a synchronization portion 300, and a connection portion 400.

[0018] (Regarding the side glass portion 100) As shown in FIG. 1, a side glass portion 100 provided in a rear door RD includes a door glass 110, a door glass frame 120, a fixing portion 130, and a lock portion LK. The rear door RD is provided with a window frame WF that houses a side glass portion 100. The window frame WF has a recess that allows the side glass portion 100 to slide in the front-rear direction of the vehicle, and holds the side glass portion 100 so that the rear door RD can be opened and closed when the side glass portion 100 is housed.

[0019] The door glass 110 is disposed in the rear door RD of the vehicle V on the upper side of the vehicle. When the side glass portion 100 is closed, the door glass 110 is stored in a window frame WF provided on the upper side of the vehicle in the rear door RD so as to be slidable in the front-rear direction of the vehicle. When stored in the window frame WF, the door glass 110 is fixed to the rear door RD by a lock portion LK.

[0020] The door glass frame 120 is fixed to the vehicle rear side of the door glass 110. The door glass frame 120 is formed of a member such as metal or resin, and is provided so as to cover the vehicle rear side of the door glass 110. A fixing portion 130 is provided on the lower rear side of the door glass frame 120, which is engaged with the connecting portion 400 when the side glass portion 100 is opened. The door glass 110, the door glass frame 120, and the fixing portion 130 are fixed to each other.

[0021] The fixing portion 130 is fixed to the lower side of the door glass frame 120 at the rear of the vehicle. As shown in FIG. 2, the fixing portion 130 has a substantially circular opening on the side facing the connecting portion 400 at the rear of the vehicle into which the lower end tuning portion 350 described later fits, and a conical fitting hole CH is formed inside the fixing portion 130 facing in the fore-and-aft direction of the vehicle and having an apex at the front of the vehicle. A fixing pin FX is provided on the vehicle underside of the fitting hole CH, which fixes the connecting part 400 and the fixed part 130 through through holes provided in the fixed part 130 and the lower end synchronization part 350. The fixing pin FX is provided so as to be movable in the vehicle up-down direction by, for example, a plunger PJ or the like.

[0022] (Regarding the slide rail portion 200) 1, the slide rail portion 200 is fixed to the vehicle body BD on the rear side of the vehicle at the upper and lower ends of the side glass portion 100, and slides the upper and lower ends of the side glass portion 100. The slide rail portion 200 is formed of a member such as metal or resin, and extends substantially linearly in the front-rear direction of the vehicle. The slide rail portion 200 is provided as an upper end rail portion 210 at the upper end of the side glass portion 100 , and as a lower end rail portion 250 at the lower end of the side glass portion 100 . 1(a), rotatable rollers RO are provided at both ends of the lower end rail portion 250 in the vehicle longitudinal direction to pull the wire WR into the vehicle body BD. A drive unit WM is provided inside the vehicle body BD. The drive unit WM moves the wire WR in the vehicle longitudinal direction by a motor or the like, thereby pulling the coupling portion 400 in the vehicle longitudinal direction via the pulling unit 420. The drive unit WM is controlled by, for example, the control unit CT.

[0023] The upper end rail portion 210 extends in the vehicle front-rear direction at the vehicle rear side of the upper end portion of the side glass portion 100, and is fixed to the vehicle body BD of the vehicle V at the vehicle rear side. 2(a), the upper end rail portion 210 is formed in a C-shape with an opening on the vehicle lower side when viewed from the front side of the vehicle. A concave groove portion is formed inside the upper end rail portion 210 to allow the side glass portion 100 to slide in the vehicle front-rear direction. A tuning section 300 is fixed to the upper end rail section 210 on the front side of the vehicle. Additionally, the upper rail portion 210 is provided with a taper such that the width UW in the vehicle width direction inside the upper rail portion 210 gradually narrows from the front side of the vehicle to the rear side of the vehicle. In other words, when the upper end of the side glass portion 100 is located on the front side of the vehicle, the gap in the vehicle width direction between the upper rail portion 210 and the upper end of the side glass portion 100 is wide, and as the upper end of the side glass portion 100 moves from the front side of the vehicle to the rear side of the vehicle, the gap in the vehicle width direction between the upper rail portion 210 and the upper end of the side glass portion 100 gradually narrows.

[0024] The lower end rail portion 250 extends in the vehicle front-rear direction at the vehicle rear side of the lower end portion of the side glass portion 100, and is fixed to the vehicle body BD of the vehicle V at the vehicle rear side. 2(b), the lower end rail portion 250 is formed in a C-shape with an opening on the outer side in the vehicle width direction when viewed from the front side of the vehicle. Also, a concave groove portion is formed inside the lower end rail portion 250, and the connecting portion 400 is slidably fitted into the groove portion. Further, the lower end rail portion 250 is provided with a taper such that the width LW in the vehicle vertical direction inside the lower end rail portion 250 gradually narrows from the front side of the vehicle to the rear side of the vehicle. Therefore, when the connecting portion 400 is located on the front side of the vehicle, the gap between the lower end rail portion 250 and the connecting portion 400 in the vehicle vertical direction is wide, and as the connecting portion 400 moves from the front side of the vehicle to the rear side of the vehicle, the gap between the lower end rail portion 250 and the connecting portion 400 in the vehicle vertical direction gradually narrows.

[0025] Further, a guide portion 260 is provided on the underside of the front portion of the vehicle of the lower end rail portion 250. The guide portion 260 is an auxiliary rail that supports the side glass portion 100 by having an upper surface portion of the guide portion 260 come into contact with the underside of the side glass portion 100 when the side glass portion 100 moves toward the rear of the vehicle. The guide portion 260 is formed of a member such as metal or hard resin as a generally L-shaped flat plate whose outer side in the vehicle width direction is bent toward the upper side of the vehicle. The guide portion 260 may be provided below the lower end rail portion 250 in the vehicle front-rear direction, extending along the lower end rail portion 250.

[0026] (Regarding tuning unit 300) As shown in Figures 3(a) and 3(b), the tuning section 300 is provided with an upper end tuning section 310 as a first tuning section that guides the upper end of the side glass section 100 to the upper end rail section 210 as the slide rail section 200, and a lower end tuning section 350 as a second tuning section that adjusts the positions of the connecting section 400 and the fixed section 130 in the side glass section 100. The tuning portion 300 is provided on the front side of the upper end rail portion 210 and on the front side of the connecting portion 400 .

[0027] When the upper end of the side glass part 100 moves towards the rear of the vehicle, the upper end synchronization part 310 guides the upper end of the side glass part 100 into a concave groove part inside the upper end rail part 210 . The upper end tuning portion 310 is formed of a material that is softer than the side glass portion 100, such as metal, resin, or hard rubber. 2(a) and 3(a), the upper end tuning portion 310 is formed in a C-shape with an opening on the vehicle lower side when viewed from the front side of the vehicle. The width UW2 of the opening in the upper end tuning portion 310 in the vehicle width direction is formed wider than the width UW1 of the opening in the upper end rail portion 210 in the vehicle width direction.

[0028] The lower end tuning section 350 is provided inside the connecting section 400 . When the side glass part 100 is moved towards the rear of the vehicle, the lower end synchronizing part 350 protrudes from a storage hole SH provided on the front side of the connecting part 400 of the vehicle and fits into a fitting hole CH provided in the fixing part 130. As shown in FIG. 3(b), the lower end tuning portion 350 is formed, for example, from a material such as metal or hard resin into a cylindrical rod shape extending in the fore-and-aft direction of the vehicle, and the front portion of the vehicle is formed into a cone shape having an apex at the front of the vehicle. The conical portion of the lower end tuning portion 350 on the vehicle front side is provided with, for example, a through hole that penetrates in the vehicle up-down direction. Further, for example, a screw hole extending from the rear side of the vehicle to the front side of the vehicle is provided on the rear side of the lower end synchronizing portion 350. A protruding operation portion 440, which will be described later, is screwed into the rear side of the lower end synchronizing portion 350. As shown in Figs. 2(b) and 3(b), the lower end tuning portion 350 is provided with a groove portion BM extending in the vehicle front-rear direction, which groove portion BM fits into a protrusion portion DB of the connecting portion 400, which will be described later.

[0029] (Regarding the connecting portion 400) As shown in FIG. 3( b ), the connecting portion 400 fits into the fixing portion 130 of the side glass portion 100 , and moves the side glass portion 100 along the lower end rail portion 250 serving as the slide rail portion 200 . The connecting portion 400 includes a housing portion 410, a pulling portion 420, a protruding switch 430, and a protruding actuation portion 440. The connecting portion 400 accommodates the lower end tuning portion 350 therein.

[0030] The housing part 410 is made of metal, hard resin, or the like and is formed in a substantially rectangular parallelepiped shape having a protruding part that protrudes outward in the vehicle width direction at a substantially central part in the vehicle up-down direction of the housing part 410. The housing part 410 is fitted into a concave recess inside the lower end rail part 250 so as to be slidable in the vehicle front-rear direction. The housing 410 has a substantially circular opening on the vehicle front side, and a substantially cylindrical storage hole SH is formed in the vehicle front-rear direction from the vehicle front to the vehicle rear. 2(b) and 3(b), a protrusion DB is provided on the inside of the storage hole SH so as to extend radially inward of the storage hole SH in the vehicle front-rear direction. The protrusion DB is fitted into a groove BM provided in the lower end synchronization part 350. The lower end synchronizing part 350 is housed in the housing hole SH so as to be movable in the front-rear direction of the vehicle. Further, a concave space is formed on the inner side of the housing part 410 in the vehicle width direction, and a traction part 420 is provided therein.

[0031] As shown in Figures 2(b) and 3(b), the towing unit 420 is provided on the inside of the housing unit 410 in the vehicle width direction, and a wire WR connected to a drive unit WM provided inside the vehicle body BD is connected to the front and rear sides of the towing unit 420. The towing unit 420 includes a cylindrical rod 421 extending in the vertical direction of the vehicle, and a towing member 422 that is provided so as to be movable in the vertical direction of the vehicle along the cylindrical rod 421, with the cylindrical rod 421 penetrating the center of the towing member 422. The cylindrical rod 421 is fixed to the housing unit 410 at the upper and lower ends of the vehicle. A wire WR is coupled in the vehicle front-rear direction to the pulling member 422. The pulling part 420 is provided so as to be movable in the vehicle width direction by the elasticity of the wire WR. The connecting portion 400 to which the towing portion 420 is fixed is in a state in which it can move in the vertical direction and the width direction of the vehicle due to the elasticity of the towing member 422 and the wire WR.

[0032] 3(b), the protruding switch 430 is provided to protrude from the vehicle front side of the connecting part 400. When the side glass part 100 is moved, the protruding switch 430 comes into contact with the side glass part 100 and is pushed into the connecting part 400 toward the vehicle rear side. The protrusion switch 430 detects whether the connecting part 400 is protruding towards the front of the vehicle, whether it is in contact with the side glass part 100, or whether it is pressed into the inside of the connecting part 400.

[0033] The protrusion operation part 440 is formed, for example, in a substantially cylindrical bolt shape, and a screw thread is formed on the vehicle front side of the protrusion operation part 440. The protrusion operation part 440 is screwed into a screw hole provided on the vehicle rear side of the lower end synchronization part 350. The protrusion operation part 440 is rotated by a rotation motor (not shown).

[0034] (About the control unit CT) The vehicle V is provided with a control unit CT that controls the vehicle side glass device 10, for example. As indicated by the thick solid arrows in FIG. 4, the control unit CT is connected to the lock unit LK in the side glass unit 100, the fixing unit 130, the connecting unit 400, and the driving unit WM.

[0035] <Actions and Effects> In the vehicle side glass device 10 according to this embodiment configured as described above, the operation of opening and closing the side glass portion 100 will be described with reference to FIGS.

[0036] (Operation of the vehicle side window device 10) The side glass portion 100 is in a closed state. When opening or closing the side glass portion 100, the operation is controlled by, for example, the control portion CT. The control portion CT, for example, determines the states of the lock portion LK and the protrusion switch 430 in the side glass portion 100, and operates the fixing portion 130 and the connecting portion 400 based on the determination result.

[0037] The control unit CT determines the state of the lock unit LK in the side glass unit 100. The control unit CT determines that the side glass unit 100 is stored in the window frame WF when the lock unit LK is ON as shown in Fig. 1(a), and determines that the side glass unit 100 is in a towable state when the lock unit LK is OFF as shown in Fig. 1(b).

[0038] In addition, the control unit CT determines the state of the protrusion switch 430 in the connecting portion 400 . Specifically, as shown in FIG. 5(a), for example, when the protrusion switch 430 is in a state in which the connecting portion 400 protrudes toward the front side of the vehicle, the control portion CT determines that the protrusion switch 430 is in an OFF state. Furthermore, when the protrusion switch 430 is in contact with the side glass portion 100, the control portion CT determines that the protrusion switch 430 is in the tuning portion ON state. When the control portion CT determines that the protrusion switch 430 is in the tuning portion ON state, the control portion CT causes the lower end tuning portion 350 to protrude toward the front side of the vehicle via the connecting portion 400. 5(b), when the protrusion switch 430 is pressed into the connecting part 400, the control part CT determines that the protrusion switch 430 is in the lock ON state. When the control part CT determines that the protrusion switch 430 is in the lock ON state, the control part CT causes the fixing pin FX to protrude to the upper side of the vehicle via the fixing part 130.

[0039] The control unit CT operates the connecting unit 400 via the drive unit WM based on the state determination results of the lock unit LK and the protrusion switch 430. The control unit CT moves the wire WR in the vehicle longitudinal direction via the drive unit WM, thereby pulling the towing unit 420 and moving the connecting unit 400 in the vehicle longitudinal direction.

[0040] Furthermore, for example, when the side glass portion 100 is closed and the lock portion LK is turned ON, the control portion CT causes the fixing pin FX of the fixing portion 130 to be accommodated under the vehicle. Then, the control portion CT causes the lower end synchronizing portion 350 to be accommodated in the accommodation hole SH, and returns the connecting portion 400 to a position on the lower end rail portion 250 at the front side of the vehicle.

[0041] (When the side glass part 100 is fully opened) When the user opens the side glass portion 100, an operation for opening the side glass portion 100 is performed using a remote control key or a switch provided on the vehicle V, for example. At this time, the side glass portion 100 is in the state shown in FIG. The control unit CT releases the locking unit LK of the side glass unit 100, thereby allowing the side glass unit 100 to slide toward the rear of the vehicle.

[0042] When the control unit CT causes the wire WR connected to the drive unit WM to pull the connecting part 400, the connecting part 400 moves from the position shown in Figure 5(a) to the front side of the vehicle, and the protruding switch 430 abuts against the rear side surface of the vehicle at the side glass part 100. When the protruding switch 430 comes into contact with the rear side of the vehicle, the control unit CT determines that the protruding switch 430 has changed from an OFF state to a tuning unit ON state, and rotates the protruding operating unit 440 to cause the lower end tuning unit 350 to protrude toward the front of the vehicle. Since the groove portion BM formed in the lower end tuning portion 350 and the protrusion portion DB formed in the housing portion 410 in the connecting portion 400 are engaged with each other, even when the protruding operating portion 440 rotates, the lower end tuning portion 350 moves toward the front of the vehicle without rotating together with the protruding operating portion 440, and protrudes from the connecting portion 400.

[0043] As shown in Fig. 5(b), the apex of the lower end tuning part 350 protruding toward the front of the vehicle fits into a fitting hole CH provided in the fixed part 130. The vehicle front part of the lower end tuning part 350 is formed in a substantially conical shape with the apex on the front side of the vehicle. The fitting hole CH provided in the fixed part 130 has a substantially circular opening, and is formed in a substantially conical shape with the apex on the front side of the vehicle inside the fixed part 130. At this time, if distortion occurs between the vehicle body BD and the rear door RD, a positional deviation occurs between the connecting part 400 and the fixed part 130. When the apex of the lower end tuning part 350 is within the range of the opening of the fitting hole CH, the cone-shaped lower end tuning part 350 and the fitting hole CH are fitted together, so that the apex of the lower end tuning part 350 is guided toward the apex of the fitting hole CH. In addition, the pulling part 420 provided on the connecting part 400 is in a state in which it can move in the vehicle vertical direction and the vehicle width direction due to the elasticity of the pulling member 422 and the wire WR. Therefore, the positional deviation between the connecting part 400 and the fixed part 130 is adjusted by the lower end tuning part 350 and the fitting hole CH.

[0044] Then, the connecting portion 400 is fitted into the fixing portion 130 as shown in FIG. 5(b). At this time, the protrusion switch 430 is pressed into the inside of the connecting part 400. The control part CT determines that the protrusion switch 430 is in the lock ON state, and the control part CT, for example, operates the plunger PJ to protrude the fixing pin FX toward the upper side of the vehicle. The fixing pin FX passes through a through hole provided in the lower end tuning portion 350, and fixes the lower end tuning portion 350 and the fixing portion 130. Then, the side glass portion 100 and the connecting portion 400 are fixed.

[0045] The control unit CT drives the drive unit WM and operates the wire WR connected to the drive unit WM, thereby causing the pulling unit 420 provided on the connecting unit 400 to pull toward the rear of the vehicle. Then, the side glass unit 100 moves toward the rear of the vehicle. The towing part 420 moves without resistance in the vehicle vertical direction and the vehicle width direction due to the elasticity of the towing member 422 that is movable in the vehicle vertical direction and the wire WR that is connected to the towing member 422. Therefore, even if distortion occurs between the vehicle body BD and the rear door RD, the positional deviation between the connecting part 400 and the fixed part 130 is adjusted without resistance.

[0046] On the other hand, when distortion occurs between the vehicle body BD and the rear door RD, a misalignment also occurs between the upper end tuning portion 310 and the side glass portion 100. When the misalignment with the side glass portion 100 is within the range of the width of the upper end tuning portion 310 in the upper end rail portion 210, the side glass portion 100 is guided by the upper end tuning portion 310 and slides on the upper end rail portion 210 toward the rear of the vehicle. Therefore, the misalignment between the upper end tuning portion 310 and the side glass portion 100 is adjusted by the side glass portion 100 being guided to the upper end rail portion 210 by the upper end tuning portion 310.

[0047] Further, the lower end rail portion 250 is provided with a taper in which the width LW in the vehicle vertical direction inside the lower end rail portion 250 gradually narrows from the front side of the vehicle to the rear side of the vehicle. Therefore, when the connecting portion 400 is located on the front side of the vehicle, the gap between the lower end rail portion 250 and the connecting portion 400 in the vehicle vertical direction is wide, and as the connecting portion 400 moves from the front side of the vehicle to the rear side of the vehicle, the gap between the lower end rail portion 250 and the connecting portion 400 in the vehicle vertical direction gradually narrows. Then, the side glass portion 100 slides stably on the slide rail portion 200 toward the rear side of the vehicle without resistance.

[0048] Then, the side glass portion 100 changes from the closed state shown in FIG. 1(a) to the fully open state shown in FIG. 1(b) and stops. The side glass portion 100 moves along the slide rail portion 200 fixed to the vehicle body BD toward the rear of the vehicle and enters a fully open state, so that the window frame portion of the rear door RD enters a fully open state. When the window frame portion of the rear door RD is in a fully open state, the passenger can place luggage inside the vehicle through the window frame portion, which has a sufficient opening range that is not restricted by the side glass portion 100. At this time, since the side glass portion 100 in the fully open state does not interfere with the rear seat door RD, the rear seat door RD can be opened and closed.

[0049] (When closing the side glass part 100) When the user closes the side glass portion 100, an operation for closing the side glass portion 100 is performed using a remote control key or a switch provided on the vehicle V, for example. At this time, the side glass portion 100 is in the state shown in FIG.

[0050] Based on the user's operation, the control unit CT causes the wire WR connected to the drive unit WM to pull the connecting part 400, and the connecting part 400 moves toward the front of the vehicle from the position in Figure 1 (b), thereby moving the side glass part 100 toward the front of the vehicle. Then, the side glass portion 100 changes from the fully open state shown in Fig. 1(b) to the closed state shown in Fig. 1(a). Then, the control unit CT locks the locking unit LK of the side glass portion 100. By the control unit CT locking the locking unit LK, the side glass portion 100 is fixed in the closed state. The connecting unit 400 goes into the state shown in Fig. 5(b).

[0051] The control unit CT determines that the lock unit LK is locked, and stores the fixing pin FX of the fixing unit 130 toward the lower side of the vehicle. The fixing pin FX is disengaged from the through hole provided in the lower end tuning unit 350, and the lower end tuning unit 350 becomes movable in the front-rear direction of the vehicle. The control unit CT rotates the protruding operation portion 440 to accommodate the lower end synchronizing portion 350 in the accommodation hole SH. Control unit CT moves coupling portion 400 toward the rear of the vehicle to a position where it does not protrude from lower end rail portion 250 toward the front of the vehicle. Coupling portion 400 returns to the state shown in FIG. At this time, the connecting portion 400 does not interfere with the rear door RD, so that the rear door RD can be opened and closed.

[0052] Then, the side glass portion 100 changes from the fully open state shown in FIG. 1(b) to the closed state shown in FIG. 1(a) and stops.

[0053] As described above, the vehicle side glass device 10 of this embodiment comprises a side glass portion 100 provided on the upper side of the rear door RD of the vehicle V, an upper end rail portion 210 and a lower end rail portion 250 which are fixed to the vehicle body BD on the rear side of the vehicle at the upper and lower ends of the side glass portion 100 and serve as a pair of slide rail portions for sliding the upper and lower ends of the side glass portion 100, a fixing portion 130 which is provided on the vehicle rear side of the side glass portion 100 and is pulled when the side glass portion 100 is opened or closed, and a connecting portion 400 which engages with the fixing portion 130 in the side glass portion 100 and pulls the side glass portion 100 along the upper end rail portion 210 and the lower end rail portion 250. That is, when opening or closing the side glass section 100 provided on the upper side of the rear door RD, the connecting section 400 fits into the fixing section 130 of the side glass section 100 and pulls the side glass section 100 in the front-rear direction of the vehicle along the slide rail section 200 fixed to the vehicle body BD, thereby opening or closing the side glass section 100. Then, the connecting section 400 moves the side glass section 100 toward the rear of the vehicle along the slide rail section 200 fixed to the vehicle body BD, thereby bringing the side glass section 100 into a fully open state. Therefore, the side glass portion 100 moves toward the rear of the vehicle along the slide rail portion 200 fixed to the vehicle body BD and becomes fully open, so that the vehicle side glass device 10 can bring the window frame portion in the rear door RD into a fully open state. Therefore, when the rear door is closed, the side glass portion can be easily opened fully.

[0054] In addition, the vehicle side glass device 10 in this embodiment is provided with an upper end tuning portion 310 as a first tuning portion that guides the upper end of the side glass portion 100 to the slide rail portion 200, and a lower end tuning portion 350 as a second tuning portion that adjusts the positions of the connecting portion 400 and the fixed portion 130 in the side glass portion 100. That is, when distortion occurs between the vehicle body BD and the rear door RD, a positional deviation occurs between the side glass portion 100 and the slide rail portion 200. When the positional deviation occurring between the vehicle body BD and the rear door RD is within the width range of the side glass portion 100 of the upper end synchronization portion 310, the upper end synchronization portion 310 guides the side glass portion 100 to the upper end rail portion 210. Then, the side glass portion 100 slides on the upper end rail portion 210 toward the rear of the vehicle. Therefore, the vehicle side glass device 10 can adjust the positional deviation between the upper end synchronization portion 310 and the side glass portion 100 by the upper end synchronization portion 310. Moreover, the vehicle front portion of the lower end synchronization portion 350 has an apex on the vehicle front side. Moreover, the fitting hole CH in the fixing portion 130 provided in the side glass portion 100 has a substantially circular opening. When a positional misalignment due to distortion occurring between the vehicle body BD and the rear door RD occurs such that the apex of the lower end tuning portion 350 at the front side of the vehicle is within the range of the opening of the fitting hole CH, the apex of the lower end tuning portion 350 is guided into the fitting hole CH by fitting into the fitting hole CH. Therefore, the vehicle side glass device 10 can adjust the positional deviation between the connecting portion 400 and the fixing portion 130 by the lower end synchronizing portion 350 and the fitting hole CH. The vehicle side glass device 10 can open and close the side glass portion without causing any discomfort even when distortion occurs between the vehicle body BD and the rear door RD. Therefore, when the rear door is closed, the side glass portion can be easily opened fully.

[0055] In the vehicle side glass device 10 according to this embodiment, the lower end tuning portion 350 serving as the second tuning portion has a conical shape. In other words, even if distortion occurs between the vehicle body BD and the rear door RD when the connecting part 400 and the fixed part 130 are engaged, if the apex of the cone is within the range of the engaging hole CH of the fixed part 130, the apex of the cone at the lower end tuning part 350 is guided into the conical shape of the engaging hole CH, thereby making it possible to adjust the positions of the connecting part 400 and the fixed part 130. Therefore, the vehicle side glass device 10 can adjust the positional deviation between the connecting portion 400 and the fixing portion 130 by the lower end synchronizing portion 350 and the fitting hole CH. The vehicle side glass device 10 can open and close the side glass portion 100 without causing any discomfort even when distortion occurs between the vehicle body BD and the rear door RD. Therefore, when the rear door is closed, the side glass portion can be easily opened fully.

[0056] Moreover, in the vehicle side glass device 10 according to this embodiment, the connecting portion 400 as the second synchronizing portion is provided with a traction portion 420 that is movable in the vehicle up-down direction and the vehicle width direction. That is, the towing unit 420 is provided on the inside of the housing unit 410 in the vehicle width direction, and a wire WR connected to the drive unit WM provided inside the vehicle body BD is coupled to the front and rear sides of the vehicle. The towing unit 420 includes a cylindrical rod 421 extending in the vehicle vertical direction, and a towing member 422 through whose center the cylindrical rod 421 penetrates in the vehicle vertical direction and which is provided so as to be movable in the vehicle vertical direction along the cylindrical rod 421. In addition, the towing unit 420 is provided so as to be movable in the vehicle width direction due to the elasticity of the wire WR. Therefore, due to the elasticity of the pulling member 422 and the wire WR, the pulling part 420 moves in the vehicle up-down direction and the vehicle width direction to adjust the positional deviation, and the connecting part 400 to which the pulling part 420 is fixed can move the side glass part 100 without resistance. Then, the vehicle side glass device 10 can open and close the side glass part 100 without any discomfort. Therefore, when the rear door is closed, the side glass portion can be easily opened fully.

[0057] In the vehicle side glass device 10 according to this embodiment, the upper end rail portion 210 and the lower end rail portion 250 as the slide rail portion 200 have the widest width on the vehicle front side. That is, the upper end rail portion 210 is provided with a taper such that the width UW in the vehicle width direction inside the upper end rail portion 210 gradually narrows from the front side of the vehicle to the rear side of the vehicle. Also, the lower end rail portion 250 is provided with a taper such that the width LW in the vehicle up-down direction inside the lower end rail portion 250 gradually narrows from the front side of the vehicle to the rear side of the vehicle. Furthermore, the width UW2 of the opening in the upper end tuning portion 310 in the vehicle width direction is formed to be wider than the width UW1 of the opening in the upper end rail portion 210 in the vehicle width direction. Therefore, even if the vehicle body BD and the rear door RD are distorted when the side glass portion 100 engages with the slide rail portion 200, the upper end rail portion 210 and the lower end rail portion 250 can guide the side glass portion 100 without resistance to the upper end rail portion 210 and the lower end rail portion 250. In addition, the side glass portion 100 can be stabilized without resistance and the slide rail portion 200 can be slid in the front-rear direction of the vehicle. Furthermore, since the upper end synchronization portion 310 is formed wider than the opening in the upper end rail portion 210, the side glass portion 100 can be guided to the upper end rail portion 210 without resistance. Thus, the vehicle side glass device 10 can open and close the side glass portion 100 without any sense of discomfort. Therefore, when the rear door is closed, the side glass portion can be easily opened fully.

[0058] When the side glass portion 100 is not fully open or closed, the control portion CT may prohibit the rear door RD from being opened or closed.

[0059] Further, although the above embodiment illustrates a case in which the side glass portion 100 is provided on the upper side of the rear door RD, the vehicle side glass device 10 may be applied to a vehicle in which the side glass portion 100 is provided on the vehicle body BD.

[0060] Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and designs that do not deviate from the gist of the present invention are also included. [Explanation of symbols]
