However, the front edge is directly connected to the upper edge of the front window 5 without sandwiching the roof skin. Strictly speaking, a weather strip 6 made of a rubber material or the like attached to the front edge of the roof panel 4 and a weather strip (hereinafter referred to as a molding) 7 made of a rubber material or the like attached to the upper edge of the front window 5 are illustrated. As shown in FIG. 2, the front edge of the roof panel 4 is flush with the upper edge of the front window 5 by lightly contacting each other. As shown in FIG. 5, the weather strip 6 has a shape including a base portion 6a attached to the front edge of the roof panel 4 and a thin tongue-like lip portion 6b extending forward from the front end of the base portion 6a. The front end of 6b is lightly in contact with the upper surface of the rear portion 7A of the molding 7.

  The mall 7 is integrally formed with a deflector 51 that suppresses entrainment of airflow into the vehicle. The deflector 51 is formed so as to protrude upward from the vicinity of the center of the molding 7 in the vehicle longitudinal direction. The deflector 51 rectifies the airflow that has flowed along the front window 5 in front of the deflector 51 in an upward direction, thereby suppressing the entrainment of the airflow into the vehicle and reducing the occurrence of wind slobs and the like. The rear portion 7A of the molding 7 is formed lower than the deflector 51. As described above, the lip portion 6b of the weather strip 6 of the roof panel 4 contacts the upper surface of the rear portion 7A.

  In FIG. 2, the front panel holder 8, the side panel holder 9, and the rear panel holder 10 are attached to the lower surfaces of the front edge, both edges, and rear edge of the roof panel 4 mainly by reinforcing the roof panel 4 with an adhesive or the like.

  As shown in FIG. 4, the side panel holder 9 includes a first upper surface portion 9a attached to the lower surface of the side edge of the roof panel 4 with an adhesive 11 and an end portion of the first upper surface portion 9a near the center in the vehicle width direction. A first side surface portion 9b extending in a downward direction substantially orthogonal to the panel surface of the roof panel 4, and slightly toward the center in the vehicle width direction so as to be substantially parallel to the panel surface of the roof panel 4 from the lower end of the first side surface portion 9b. A lower surface portion 9c extending while inclining upward, a second side surface portion 9d extending upward from an end of the lower surface portion 9c near the center in the vehicle width direction, and extending from the upper end of the second side surface portion 9d toward the center in the vehicle width direction. And a second upper surface portion 9e attached to the lower surface of the roof panel 4 with an adhesive 12, and a substantially vertical plate-shaped bracket portion 9f extending downward from an end of the second upper surface portion 9e near the center in the vehicle width direction. It has a cross-sectional shape. The first side surface portion 9b, the lower surface portion 9c, and the second side surface portion 9d formed so as to close the lower surface of the roof panel 4 form a closed cross-sectional space as a reinforcing function. A panel support stay 38 is connected to the bracket portion 9f as described later.

  As shown in FIG. 7, the rear panel holder 10 includes an upper surface portion 10a attached to the lower surface of the rear edge of the roof panel 4 with an adhesive 13, a front surface portion 10b extending downward from the front end of the upper surface portion 10a, and a front surface portion 10b. From a cross-sectional shape having a lower surface portion 10c extending rearward from the lower end substantially parallel to the panel surface of the roof panel 4, and a rear surface portion 10d extending upward from the rear end of the lower surface portion 10c and connected to the rear end of the upper surface portion 10a. Thus, a substantially rectangular closed cross-sectional space is formed by these four surfaces. The rear panel holder 10 is attached to the lower surface slightly forward of the rear edge of the roof panel 4.

  As shown in FIG. 11, both end portions of the front panel holder 8 and the front end portion of the side panel holder 9 are connected by a front joint member 29, and both end portions of the rear panel holder 10 and the rear end portion of the side panel holder 9 are connected. Connected by the rear joint member 30. The upper surfaces of the front joint member 29 and the rear joint member 30 are also bonded to the lower surfaces of the four corners of the roof panel 4 with an adhesive or the like as appropriate. The front joint member 29 and the rear joint member 30 are made of a resin member, for example.

  As shown in FIG. 2, a front roof rail 15 is attached to the inner surface of the upper edge of the front window 5 with an adhesive 14. The front roof rail 15 is a member extending in the vehicle width direction for ensuring the strength of the front window 5 and has a substantially closed cross-sectional structure. The front roof rail 15 is made of a single metal plate, for example, a plated steel plate formed by bending such as roll forming.

  As shown in FIG. 5, the front roof rail 15 is attached to the inner surface of the upper edge of the front window 5 via an adhesive 14, and the front roof rail 15 is substantially orthogonal to the window surface of the front window 5 from the rear end of the mounting surface 15a. An upper rear surface portion 15b extending in a downward direction, a concave surface portion 15c folded back slightly upward in an arc shape so as to be concave from the lower end of the upper rear surface portion 15b to the rear side and upward, and a concave surface portion 15c A support surface 15d extending substantially horizontally rearward from the rear end, a lower rear surface 15e extending substantially vertically downward from the rear end of the support surface 15d, and inclined obliquely downward from the lower end of the lower rear surface 15e toward the front. The lower surface portion 15f extends and the inclined surface 15g extends obliquely upward from the front end of the lower surface portion 15f and extends forward. The upper end of the inclined surface 15g is a portion that is the foremost end position of the front roof rail 15, and is folded upward and continues to the front end of the mounting surface portion 15a.

  Due to the outer shape of the front roof rail 15 described above, the closed cross-sectional space 16 of the front roof rail 15 mainly includes the mounting surface portion 15a with the narrow portion 16c formed by the concave surface portion 15c and the inclined surface 15g being close to each other. A front space 16a surrounded by the upper rear surface portion 15b and the inclined surface 15g and a rear space 16b mainly surrounded by the support surface portion 15d, the lower rear surface portion 15e, and the lower surface portion 15f are defined. The front space 16a is located immediately below an attachment surface portion 15a that is an attachment portion with the front window 5. The rear space 16b is connected to the lower rear of the front space 16a and is located immediately below the front edge of the roof panel 4 when closed, that is, directly below the front panel holder 8.

  As described above, since the front roof rail 15 is a member obtained by bending a single metal plate, the joint portion 17 of the plate is formed. The front roof rail 15 shown in FIG. 5 shows a case where the joint portion 17 is formed so as to be positioned on the mounting surface portion 15a, and the rigidity of the front roof rail 15 is increased by closing the joint portion 17 with the adhesive 14. Yes. As another example, as shown in FIG. 6, a joint member 18, which is a separate member, may be attached by welding so as to close the joint portion 17. In this case, since the blocking with the adhesive 14 is not necessary, the front roof rail 15 may be formed so that the joint portion 17 is located at a portion other than the attachment surface portion 15a.

  Next, a drain groove for draining rainwater or the like is disposed below the entire periphery of the edge of the roof panel 4. First, as shown in FIG. 5, a front roof stiffener 19 extending in the vehicle width direction is disposed above the front roof rail 15. The front roof stiffener 19 includes a substrate portion 19a located between the upper edge of the front window 5 and the mounting surface portion 15a of the front roof rail 15, and a downward direction substantially orthogonal to the window surface of the front window 5 from the rear end of the substrate portion 19a. Side plate portion 19b extending to the rear, bottom plate portion 19c extending substantially horizontally rearward from the lower end of the side plate portion 19b, and seal mounting that is bent slightly upward from the rear end of the bottom plate portion 19c and then extends rearward substantially horizontally And a cross-sectional shape having a plate portion 19d. In the front roof stiffener 19, the front end of the base plate portion 19a is fixed to the mounting surface portion 15a of the front window 5 and the front roof rail 15 by the adhesive 14, and the rear surface of the bottom plate portion 19c and the lower surfaces of the seal mounting plate portion 19d are adhesive 20 respectively. Thus, the front roof rail 15 is fixed to the support surface portion 15d.

  A seal member 21 extending in the vehicle width direction is fixed to the upper surface of the seal mounting plate portion 19d with an adhesive or the like. The seal member 21 is made of, for example, a rubber material having a hollow closed cross-sectional shape. When the cover is closed, the lower surface portion 8c of the front panel holder 8 is pressed against the seal member 21, so that the periphery of the front edge of the roof panel 4 is in a water-tight state and water intrusion into the vehicle is prevented. That is, the front edge of the roof panel 4 is placed on the rear space 16 b of the front roof rail 15 via the front roof stiffener 19. A drain groove 22 is formed by the side plate portion 19 b, the bottom plate portion 19 c, and the front side surface 21 a of the seal member 21. The water received in the drain groove 22 is drained through the front pillars through drain holes (not shown) formed around both ends of the drain groove 22 in the vehicle width direction.

  As shown in FIG. 4, a side roof stiffener 23 extending in the vehicle front-rear direction is disposed below the side edge of the roof panel 4. The side roof stiffener 23 includes a substantially horizontal connecting plate portion 23a connected to a vehicle-side frame (not shown), and a first side plate extending substantially vertically downward from an end of the connecting plate portion 23a near the center in the vehicle width direction. Portion 23b, a bottom plate portion 23c extending substantially horizontally from the lower end of the first side plate portion 23b toward the center in the vehicle width direction, and a second plate extending substantially vertically from the end of the bottom plate portion 23c near the center in the vehicle width direction. It has a cross-sectional shape having a side plate portion 23d and a seal attachment plate portion 23e extending while slightly tilting upward from the upper end of the second side plate portion 23d toward the center in the vehicle width direction.

  A seal member 24 extending in the vehicle front-rear direction is fixed to the upper surface of the seal mounting plate portion 23e with an adhesive or the like. The seal member 24, the seal member 21, and a seal member 27 to be described later are members integrally formed as a square frame shape. When the side panel holder 9 is closed, the lower surface portion 9c of the side panel holder 9 is pressed against the seal member 24, so that the periphery of the side edge of the roof panel 4 is in a watertight state to prevent water from entering the vehicle. A drain groove 25 is formed by the first side plate portion 23b, the bottom plate portion 23c, and the second side plate portion 23d. The water received in the drain groove 25 is drained through a drain hole (not shown) via a front pillar, a center pillar, and the like.

  As shown in FIG. 7, a rear roof stiffener 26 extending in the vehicle width direction is disposed below the rear edge of the roof panel 4. The rear roof stiffener 26, the front roof stiffener 19 and the side roof stiffener 23 are members integrally connected as a square frame shape. The rear roof stiffener 26 includes a substantially horizontal connecting plate portion 26a connected to a vehicle body frame (not shown), a side plate portion 26b extending downward from the front end of the connecting plate portion 26a, and a front side from the lower end of the side plate portion 26b. It has a cross-sectional shape having a bottom plate portion 26c that extends horizontally and a seal mounting plate portion 26d that is bent slightly upward from the front end of the bottom plate portion 26c and extends substantially horizontally forward.

  A seal member 27 extending in the vehicle width direction is fixed to the upper surface of the seal mounting plate portion 26d with an adhesive or the like. When the roof panel 4 is closed, the front panel holder 8 and the side panel holder 9 are pressed against the seal members 21 and 24, respectively, with respect to the front edge and the side edge of the roof panel 4 as described above. With respect to the rear edge of the roof panel 4, the rear panel holder 10 is not pressed against the seal member 27, but the lower surface of the rear edge of the roof panel 4 is pressed against the seal member 27, so that the periphery of the rear edge of the roof panel 4 is watertight. It becomes a state and the inundation into the vehicle is prevented. A drain groove 28 is formed by the side plate portion 26 b, the bottom plate portion 26 c, and the side surface 27 a on the rear side of the seal member 27. The water received in the drain groove 28 is drained via the center pillar through drain holes (not shown) formed around both ends of the drain groove 28 in the vehicle width direction.

  Here, with respect to the rear edge of the roof panel 4, there is the following problem due to the structure in which the lower surface of the roof panel 4 is directly pressed against the seal member 27 without using the rear panel holder 10. As shown in FIG. 4, since the side panel holder 9 is pressed against the seal member 24 at the side edge of the roof panel 4, the height of the side panel holder 9 is between the roof panel 4 and the seal member 24. Minute distance exists. On the other hand, as shown in FIG. 7, the distance between the roof panel 4 and the seal member 27 becomes zero, so that the rear portion of the seal mounting plate portion 23e of the side roof stiffener 23 is rearward as shown in FIG. It is formed as an inclined surface 23f that gradually approaches the roof panel 4 as it goes to. Accordingly, the inclined surface gradually approaches the roof panel 4 as it goes rearward around the rear portion of the lower surface portion 9c of the side panel holder 9 so as to be pressed against the sealing member 24 disposed in an inclined manner on the inclined surface 23f. 9g (see also FIG. 11).

  As shown in FIG. 12B, when the side panel holder 9 is configured to extend rearward as it is, the lower surface portion 9c is always provided between the rear end of the lower surface portion 9c, the roof panel 4, and the seal member 24. A gap G due to the plate thickness dimension is formed, and there is a possibility that a sufficient watertight state cannot be obtained. On the other hand, the formation of the gap G can be prevented by interposing the rear joint member 30 at the rear part of the side panel holder 9 as shown in FIG. The lower surface of the rear joint member 30 is formed in an inclined shape so as to be flush with the inclined surface 9g of the side panel holder 9, and the inclined surface 30b is formed to a position that substantially contacts the lower surface of the roof panel 4 ( (See also FIG. 11). Thereby, the gap G is not formed, and a predetermined watertight function is ensured. Since the side panel holder 9 is a sheet metal member, it is substantially impossible to cut the rear end of the lower surface portion 9c at an acute angle so that the gap G is not formed, whereas the rear joint member 30 has excellent formability. When a resin member is used, the rear end portion 30a of the rear joint member 30 can be easily formed as a dotted acute angle.

Next, the opening / closing mechanism of the roof panel 4 will be described.
In FIG. 4, guide frames 31 extending in the front-rear direction of the vehicle are disposed below both side edges of the roof panel 4. The guide frame 31 includes a cable groove 33 for inserting a push-pull cable 32 that moves back and forth by a drive motor (not shown), and a drive slider 34 connected to the push-pull cable 32 (the connection portion between them is not shown). It has a cross-sectional shape having a guide rail groove 35 for guiding the slide, and is made of, for example, an extruded shape of aluminum alloy.

  The drive slider 34 has a vertical plate-like main body 34A that stands up along the guide frame 31, and a plurality of shoes 34B that protrude from the lower part of the front and rear ends of the main body 34A and slide in the guide rail groove 35. Have The shoe 34B may be formed integrally with the main body portion 34A or may be a separate member. As shown in FIG. 2, a first lift guide groove 36 and a second lift guide groove 37 are formed in the main body portion 34A in a groove shape that penetrates the main body portion 34A from side to side.

  The first lift guide groove 36 includes a first horizontal stroke 36A extending substantially horizontally, a first inclined stroke 36B that gently tilts forward from the front end of the first horizontal stroke 36A, and an upper end of the first inclined stroke 36B. The first horizontal stroke 36C extends substantially horizontally forward from the second horizontal stroke 36C, and the second horizontal stroke 36D tilts forward from the front end of the second horizontal stroke 36C. The second lift guide groove 37 includes a first horizontal stroke 37A that extends substantially horizontally, an inclined stroke 37B that inclines forward from the front end of the first horizontal stroke 37A, and a substantially horizontal front from the upper end of the inclined stroke 37B. And a second horizontal stroke 37 </ b> C extending in the shape.

  A panel support stay 38 is interposed between the roof panel 4 and the drive slider 34. Referring to FIGS. 2 and 3, panel support stay 38 is a plate-like member arranged vertically, and has a base portion 39 formed on the front side and a bifurcated shape formed on the rear side. It has a shape having a portion 40. The forked portion 40 is formed in a forked shape so that an upper side portion 41 connected to the roof panel 4 and a lower side portion 42 engaged with the drive slider 34 open rearward. The upper side portion 41 extends substantially in the front-rear direction along the lower surface of the roof panel 4, and one of the plurality of connecting pins 43 is connected and fixed to the rear end thereof. The lower side portion 42 is also extended substantially in the front-rear direction, and a second lift guide pin 45 is attached to the rear end thereof as will be described later.

  In FIG. 4, as described above, a part of the side panel holder 9 is formed as a vertical plate-like bracket portion 9f, and the bracket portion 9f has a substrate portion 39 of the panel support stay 38 as shown in FIG. Around the upper edge and the upper side portion 41 are connected and fixed by a plurality of connecting pins 43. A first lift guide pin 44 and a second lift guide pin 45 are attached to the lower edge front end of the substrate portion 39 and the rear end of the lower side portion 42 of the panel support stay 38, respectively. The first lift guide pin 44 and the second lift guide pin 45 are slidably engaged with the first lift guide groove 36 and the second lift guide groove 37 of the drive slider 34, respectively.

  The panel support stay 38 may be formed integrally with the side panel holder 9 or may be directly attached to the lower surface of the roof panel 4 with an adhesive or the like regardless of the side panel holder 9. .

"Action"
The operation of the sunroof apparatus 1 will be described mainly with reference to FIGS. 8 and 9, the bracket portion 9f of the side panel holder 9 is omitted. FIG. 8A shows a state in which the roof panel 4 is fully closed. At this time, the drive slider 34 is at the foremost position. The first lift guide pin 44 is positioned at the first horizontal stroke 36 </ b> A of the first lift guide groove 36, and the second lift guide pin 45 is positioned at the first horizontal stroke 37 </ b> A of the second lift guide groove 37. The front panel holder 8 is pressed against the seal member 21 at the front edge of the roof panel 4, and the side panel holder 9 is pressed against the seal member 24 at the side edge of the roof panel 4 (see FIG. 4). At the edge, the lower surface of the roof panel 4 is pressed against the seal member 27, so that the water-tight state of the roof panel 4 is secured.

  When the drive slider 34 moves rearward through the push-pull cable 32 (FIG. 4) by driving a motor (not shown) from the state of FIG. 8A, the inner wall of the first inclined stroke 36B of the first lift guide groove 36 is moved. The first lift guide pin 44 is pushed upward, and the inner wall of the inclined stroke 37B of the second lift guide groove 37 pushes the second lift guide pin 45 upward, so that the roof panel 4 is moved slightly rearward and tilted up. The FIG. 8B shows a state in which the tilt-up is completed. The first lift guide pin 44 is positioned in the second horizontal stroke 36C of the first lift guide groove 36, and the second lift guide pin 45 is in the second lift. It is located at the second horizontal stroke 37 </ b> C of the guide groove 37.

  When the drive slider 34 moves further rearward from the state of FIG. 8B, the inner wall of the second inclined stroke 36D of the first lift guide groove 36 moves the first lift guide pin 44 as shown in FIG. 9A. By pushing backward, the roof panel 4 slides backward.

  When the vehicle is traveling, the airflow flowing along the front window 5 is rectified upward by the deflector 51, so that the entrainment of the airflow into the vehicle is suppressed and the occurrence of wind slob etc. Is reduced.

  FIG. 9B shows a state in which the roof panel 4 has moved to the rearmost position and the opening 3 has been fully opened. The upper side 41 of the panel support stay 38 is more than the fixed roof 2 behind the opening 3. Is also located above, and the lower side portion 42 is located below the fixed roof 2. That is, the forked portion 40 of the panel support stay 38 is positioned so as to sandwich the fixed roof 2 behind the opening 3 vertically. And the position of the 2nd lift guide pin 45 is located back rather than the rear edge of the opening part 3, as FIG.9 (b) shows.

  In the conventional structure shown in Japanese Patent Application Laid-Open No. 2005-41345, when the opening is in a fully open state, the two pins that connect the panel support stay and the slider are both positioned in front of the rear edge of the opening. In this conventional structure, unless the front pin is laid out forward by extending the front end of the guide rail forward, the span between the two pins, that is, the weight of the roof panel received by the slider is increased. It ’s difficult. In this conventional structure, the positions of the two pins are too biased forward of the center of gravity of the roof panel, so that the moment is increased and the panel support stay is easily loaded.

  On the other hand, when the opening 3 is in the fully open state, the second lift guide pin 45 is located behind the rear edge of the opening 3, that is, a panel that is a part of the weight support portion of the roof panel 4. Since a part of the engaging portion between the support stay 38 and the drive slider 34 is positioned behind the rear edge of the opening 3, measures such as extending the front end of the guide frame 31 forward are taken. Without this, the support span S (FIG. 3) of the roof panel 4 can be increased while securing the opening amount of the opening 3. In addition, since the weight supporting portion of the roof panel 4 is closer to the rear and close to the position of the center of gravity of the roof panel 4 than in the conventional case, the load on the panel support stay 38 is also reduced.

  Further, as a shape of the panel support stay 38, a forked shape formed so that an upper side portion 41 connected to the roof panel 4 and a lower side portion 42 engaged with the driving slider 34 are opened rearward. 9B, when the opening 3 is fully open as shown in FIG. 9B, the bifurcated portion 40 is positioned so as to sandwich the fixed roof 2 behind the opening 3 vertically. By doing so, it is possible to increase the support span S of the roof panel 4 while making the panel support stay 38 simple.

  As described above, the sun roof device 1 is configured such that the opening 3 of the roof is closed by connecting the front edge of the movable roof panel 4 to the upper edge of the front window 5 without sandwiching the roof outer plate of the fixed roof 2. As a result, there is no roof outer plate between the front window 5 and the roof panel 4, so that the field of view on the oblique front side can be widened. Furthermore, in the past, the deflector was positioned in the opening 3 of the roof, but the field of view of the opening 3 of the roof was increased by forming the deflector 51 on the molding 7 attached to the upper edge of the front window 5. Secured.

  Further, in the prior art (for example, Japanese Patent Application Laid-Open No. 2010-163112), the front roof rail is divided into two upper and lower members, and the flange portion for welding and joining the two members is more likely to hinder the visibility. Since the front roof rail 15 according to the embodiment has a configuration in which one metal plate is bent so as to have a substantially closed cross-sectional structure, a flange portion is not required, and accordingly, the forward oblique upper view is further widened. Can do. Since the front roof rail 15 has a structure in which at least a part (the front space 16a) of the closed cross-sectional space 16 is located immediately below the attachment portion with the front window 5, the reinforcing function of the front window 5 is sufficiently ensured.

  If the joint portion 17 of the plate of the front roof rail 15 is closed by the joining member 18, the rigidity (mainly torsional rigidity) of the front roof rail 15 can be further increased. Further, when the front roof rail 15 is bonded to the front window 5 with the adhesive 14 as in this embodiment, the rigidity of the front roof rail 15 can be achieved with a simple structure if the joint portion 17 is closed with the adhesive 14. Can be increased.

  Further, when the opening 3 is closed, if the front edge of the roof panel 4 is placed above the closed sectional space 16 of the front roof rail 15, specifically above the rear space 16 b, The load can be effectively received by the rigidity function of the closed cross-sectional space 16. Since there is no need to separately form a flange portion or the like for mounting the front edge of the roof panel 4, the space around the mounting space becomes compact, and as shown in FIG. 10, the intersection angle θ between the line of sight V1 and the line of sight V2 is It becomes small and can widen the field of view on the front diagonal.

  The deflector 51 is located in the range of the intersection angle θ between the line of sight V1 and the line of sight V2, and does not enter the occupant's field of view by being blocked by the front roof rail 15. Therefore, the problem that the field of view is narrowed by the deflector 51 does not occur.

  A modification of the deflector 51 is shown in FIGS. This modification is an example in which the deflector 51 has a configuration in which the height thereof is changed in the vehicle width direction, that is, an uneven shape in the vehicle width direction. FIG. 13 shows an example in which the height of the central portion in the vehicle width direction of the deflector 51 is made low, that is, the concave portion 51B, and the height on both the left and right sides is made high, that is, the convex portion 51A. FIG. 14 is a cross-sectional view of the formation portion of the concave portion 51B. In general, the momentum of the traveling wind that tends to enter the opening 3 of the roof tends to be stronger around the left and right front corners of the opening 3 than in the vicinity of the center of the front edge of the opening 3. If the height of the protrusion of the deflector 51 is increased, the rectifying effect is improved, but the wind pressure is increased correspondingly and the running resistance of the vehicle is increased. Therefore, the height of the deflector 51 is set high around the left and right front corners of the opening 3 where the airflow is relatively strong, and the opening 3 is relatively weak against the center of the front edge of the opening 3 where the airflow is relatively weak. Therefore, by setting the height of the deflector 51 low, it is possible to achieve a good balance between the rectifying function and the reduction of the running resistance in the entire deflector 51. Depending on the vehicle, the concavo-convex shape layout is not limited to that shown in FIG. 13, and for example, two or more concave portions may be formed, thereby improving the rectification characteristics.

  Further, in the case where the front roof rail 15 having a structure in which at least a part of the closed section space 16 (the front space 16a) is located immediately below the attachment portion with the front window 5, the front roof rail 15 is provided at the front lower portion and forward. If an inclined surface 15g is formed that is inclined obliquely upward and the upper end of the inclined surface is the frontmost end position of the front roof rail 15, as shown in FIG. 10, the line of sight V1 from the seated occupant is along the surface of the inclined surface 15g. Therefore, a large field of view of the front window 5 can be secured.

  When the opening 3 is closed, the front panel holder 8 is pressed against the seal member 21 at the front edge of the roof panel 4, and the lower surface of the roof panel 4 is directly pressed against the seal member 27 at the rear edge of the roof panel 4. With this configuration, the space in the vertical direction of the seal structure around the rear edge of the roof panel 4 can be reduced compared with the case where the rear panel holder 10 is pressed against the seal member 27, so that a large head clearance is ensured accordingly. it can.

  Further, as shown in FIG. 12A, the resin rear joint member 30 is formed with an inclined surface 30b that is inclined upward as it goes rearward until the rear end portion 30a substantially comes into contact with the lower surface of the roof panel 4. If the inclined surface 30b of the rear joint member 30 is pressed against the seal member 24 extending from the pressure contact portion with the side panel holder 9 to the pressure contact portion with the lower surface of the rear edge of the roof panel 4, the roof The generation of the gap G as shown in FIG. 12B between the panel 4 and the seal member 24 can be prevented, and the water tightness of the seal member 24 is improved.

  Further, if the drain grooves 22 and 28 are formed in the front roof stiffener 19 and the rear roof stiffener 26, respectively, and the seal members 21 and 27 are part of the groove walls of the drain grooves 22 and 28, the drain function and the roof A part of the watertight function of the panel is combined, and the structure around the drain grooves 22 and 28 becomes compact. Further, the cross-sectional shapes of the front roof stiffener 19 and the rear roof stiffener 26 may be simple shapes. Of course, also in the side roof stiffener 23, the seal member 24 may be configured as a part of the groove wall of the drain groove 25.

  The preferred embodiments of the present invention have been described above. In the embodiment described above, the drive slider 34 is configured as a single unit, but the slider may be configured to be divided.
