Abstract

[Problem] To provide a guide structure of a sunroof panel at low cost. [Solution] A guide rail (9) of a guide structure (4), which movably supports a sunroof panel, is configured from a metal guide rail (7) and a resin guide rail (8). Slide grooves (23, 25), which allow sliding of a panel bracket (13) which is a member to be guided, and raising/lowering guide grooves (28), which allow tilting of the panel bracket (13), are formed in the resin guide rail (8). The metal guide rail reinforces the resin guide rail to ensure rigidity. Because there is no need to form a complicated shape for supporting the panel bracket in the metal guide rail, the metal guide rail can be formed by folding and bending sheet metal, and manufacturing costs can be kept low.

Description

Guide rail for sunroof panel, method for manufacturing the same, and guide structure for sunroof panel

The present disclosure relates to a guide rail that supports a sunroof panel so as to be slidable and liftable, a manufacturing method thereof, and a guide structure.

For example, a structure described in Patent Document 1 is known as a guide structure that supports a sunroof panel attached to an opening of a roof so that the roof (roof) of a vehicle can be opened and closed. The guide structure of Patent Document 1 supports the sunroof panel so that the sunroof panel can be displaced. The sunroof panel has a closed position in which the opening of the roof is closed, a position in which the rear part is tilted up from the closed position, and a rear part is tilted from the closed position. After moving down, it slides backward and displaces between the open positions. The guide rail has two stages, and a rear slider driven by a drive motor slides on the lower side of the guide rail, and a panel bracket connected to the rear slider slides on an upper stage of the guide rail. The panel bracket slides with the rear slider within a predetermined range, and at the front end of the predetermined range, the panel bracket is tilted up as the rear slider slides by the cam mechanism. Therefore, the upper rail is opened upward so that the panel bracket can be tilted up. Conventionally, such a complicated guide rail has been formed by processing an extruded aluminum alloy.

The guide rail structure described in Patent Document 2 is obtained by fitting a rail made of a resin molded part to a rail body made of an extruded product of an aluminum alloy. Since the sliding member made of metal slides on the resin molded part instead of the rail body made of an aluminum alloy, it is possible to prevent the generation of abnormal noise during sliding and the shaving of the surface treatment of the guide rail.

JP 2009-90964 A Japanese Utility Model Publication No. 5-82629

However, extrusion molding with an aluminum alloy has a high material and processing cost. Moreover, in the guide structure described in Patent Document 2, since the rail body made of an aluminum alloy has a complicated shape, the work of attaching the resin molded part to the rail body is complicated, which causes an increase in the cost of the assembly work. It was. The present invention has been made in view of such a background, and an object of the present invention is to provide a sunroof panel guide rail, a guide structure, and a manufacturing method thereof that can be manufactured at low cost.

An embodiment of the present invention is a guide rail (9, 109) for guiding a guided member (13) for moving the sunroof panel (6), and has a channel (15) along the longitudinal direction. Alternatively, a resin guide rail having a metal guide rail (7, 107) including a plurality of metal bent products and a sliding guide groove (23, 25, 123) fitted in the channel and extending in the longitudinal direction. (8, 108). Another aspect of the present invention is a guide structure (4) for movably supporting the sunroof panel (6), having a channel (15) along the longitudinal direction, and one or a plurality of metal bending processes. Metal guide rails (7, 107) including a product, a resin guide rail (20) fitted in the channel and having a guide portion (26) along the longitudinal direction, and a panel bracket attached to the sunroof panel (13), a slider (12) for interlocking the panel bracket, and a sliding member (10) fixed to the slider and sliding in the longitudinal direction inside the guide portion. . Further, an embodiment of the present invention is a method for manufacturing a guide rail (9, 109) for guiding a guided member (13) for moving the sunroof panel (6), and is formed by bending a sheet metal. Creating a metal guide rail (7, 107) comprising at least one metal rail substrate (16, 17, 116) and having a channel (15) along the longitudinal direction; and a guide along the longitudinal direction. And attaching a resin guide rail (8, 108) having portions (23, 25, 26, 123) to the metal rail base so as to be disposed in the channel.

According to these configurations, the sliding guide groove or guide part, which is the main part of the guide rail, is created by the resin guide rail, and its rigidity is reinforced by the metal rail. Therefore, the structure of the metal guide rail becomes simple enough to be manufactured by bending, and the processing cost can be suppressed. Moreover, the range of selection of the material for the metal guide rail is expanded as compared with the extrusion processing, and an inexpensive material can be selected to suppress the material cost. Furthermore, since the guided member or sliding member such as the panel bracket slides with respect to the resin guide rail, the metal guide rail is not affected by wear by the sliding portion of the guided member or sliding member.

In another embodiment of the present invention, in the above configuration, the resin guide rail (20) is configured to guide the elevating and lowering of at least one end of the guided member relative to the sliding guide groove. It has the raising / lowering guide part (29) containing the raising / lowering guide groove (28) connected to a groove | channel.

According to this configuration, since the resin rail includes the sliding groove and the lifting groove, the assembly cost can be suppressed.

According to another embodiment of the present invention, in the above configuration, the metal guide rail includes a pair of metal rail base materials (16, 17, 116) made of the two bent metal products. The metal rail base materials are fixed to each other along the longitudinal direction.

According to this configuration, the metal guide rail can be easily formed as compared with the case where the metal guide rail is formed by performing a complicated bending process from one sheet metal. Also, by fixing the two metal rail bases later, the resin guide rail can be attached to the metal guide rail from the direction perpendicular to the longitudinal direction, making assembly work easier and reducing assembly costs. can do.

According to another embodiment of the present invention, in the above configuration, at least one of the pair of metal rail bases (16, 116) extends toward the other of the pair of metal rail bases. It has a plurality of fixed tabs (16d, 116d).

According to this configuration, since the overlapping area is reduced, the guide rail is reduced in weight and the material cost can be suppressed.

According to the present invention, the guide rail and guide structure of the sunroof panel can be provided at low cost.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the sunroof device 1 is attached to the roof 3 of the vehicle 2. The sunroof device 1 includes a guide structure 4 attached to the vehicle 2 and a sunroof panel 6 that is movably supported by the guide structure 4 and opens and closes the opening 5 of the roof 3. In the following description, the front-rear, left-right, and up-down directions follow the directions shown in the drawings that match the front-rear, left-right, up-down directions of the vehicle 2. The sunroof panel 6 slides backward between the closed position where the opening 5 of the roof 3 is closed and the position where the rear part is tilted up and the opening 5 is opened, and after the closed position and the rear part are tilted down. Is displaced between the position opened from the front side. The sunroof panel 6 is formed of, for example, plate glass or the like, and a weather strip 6a made of an elastic material is installed on the entire periphery of the sunroof panel 6 in order to ensure the sealing property with the opening 5. FIG. 2 shows a portion of the guide structure 4 provided on the left side of the opening 5.

First, the overall structure of the guide structure 4 will be described. As shown in FIGS. 1 to 4, the guide structure 4 includes a pair of left and right guide rails 9 each including a metal guide rail 7 and a resin guide rail 8 fixed inside the metal guide rail 7, and a pair of left and right racks. A pair of left and right sliders 12 that are driven by a drive motor 11 via a belt 10 to slide on a guide rail 9 and a sunroof panel 6 are attached, and are guided by the guide rail 9 by being connected to the slider 12. And a pair of left and right panel brackets 13. The panel bracket 13 is interlocked with the slider 12. When the slider 12 slides in the front part of the slidable range of the guide rail 9, the cam mechanism 14 provided on the slider 12 and the panel bracket 13 causes the panel bracket 13 to move up and down in a circular arc shape. As a result, the sunroof panel 6 is displaced between a position where the rear end side is tilted up from the closed position and a position where the rear end side is tilted down from the closed position across the closed position where the opening 5 is closed. When the slider 12 slides in the rear part of the slidable range of the guide rail 9, the panel bracket 13 whose rear end side is tilted down is guided to the guide rail 9, so that the sunroof panel 6 is It is accommodated or detached between the panel and the interior panel.

Next, the detailed structure of each member of the guide structure 4 will be described. The guide structure 4 is generally bilaterally symmetric. For example, a pair of left and right guide rails 9 are attached to the left and right sides of the opening 5 of the roof 3. Therefore, in the following description of the detailed structure of each member, the left member will be described unless otherwise specified. The member on the right side corresponds to a configuration in which the left and right in the description of the left member are reversed.

The guide rail 9 is mostly formed of a resin guide rail 8 for partially guiding the slider 12 and the panel bracket 13, and its rigidity is reinforced by the metal guide rail 7.

The metal guide rail 7 is a long member extending in the front-rear direction, and a channel 15 is formed along the front-rear direction. The metal guide rail 7 has two separate base materials on the left and right sides, that is, a first metal rail base material 16 disposed on the inner side in the left-right direction with respect to the vehicle 2 and a second metal disposed on the outer side in the left-right direction. It is formed by joining the rail base material 17. Each of the first metal rail base material 16 and the second metal rail base material 17 is a metal bent product formed by bending a sheet metal. As the sheet metal, a hot-dip galvanized steel plate is suitable, but other steel plates and metal plates may be used.

As shown in FIG. 2, the first metal rail base 16 includes a lower wall 16a, a side wall 16b standing at the right end of the lower wall 16a, and a lip extending leftward at the upper end of the side wall 16b. And a wall 16c. A plurality of tabs 16d extending leftward are formed on the left side of the lower wall 16a. The second metal rail base member 17 includes a lower wall 17a, a side wall 17b erected at the left end of the lower wall 17a, and a lip wall 17c extending rightward at the upper end of the side wall 17b. The right end of the lower wall 17a extends in the front-rear direction, but may be changed so that a tab is provided at a position corresponding to the tab 16d of the first metal rail base 16. As shown in FIG. 3, the lower wall 16a of the first metal rail base material 16 is overlapped on the right end side of the lower wall 17a of the second metal rail base material 17, and the tab 16d and the lower wall 17a overlapping the tab 16d By caulking, the first metal rail base material 16 and the second metal rail base material 17 are coupled to each other. In a portion other than the caulking portion where the tab 16d is formed, the overlapping width of the lower wall 16a of the first metal rail base material 16 and the lower wall 17a of the second metal rail base material 17 is small. That is, the metal guide rail 7 is reduced in weight because the shape of the first metal rail base 16 other than the caulking portion is reduced. Since the

lip walls

16c and 17c have a shorter width in the left-right direction than the corresponding

lower walls

16a and 17a, the upper surface of the metal guide rail 7 is opened in a strip shape in the front-rear direction.

The resin guide rail 8 is made of a resin such as polypropylene and is injection molded or extruded. As shown in FIGS. 2 and 3, the resin guide rail 8 is fitted inside the first metal rail base 16 and the first resin rail 19 fitted inside the first metal rail base 16. Second resin rail 20.

The first resin rail 19 has a U-shape that is open toward the left side in the left-right direction in a cross-sectional view. The first resin rail 19 is fitted to the first metal rail base material 16 so that the U-shaped outer surface of the first resin rail 19 is substantially in contact with the inner surface of the first metal rail base material 16. The upper left end of the first resin rail 19 extends to the left from the left end of the lip wall 16 c of the first metal rail base 16. The first resin rail 19 is fixed to the first metal rail base 16 by rivets 21. The 1st resin rail 19 and the 1st metal rail base material 16 are good also as a structure fixed by giving an engagement shape mutually. The U-shaped inner surface of the first resin rail 19 is a groove extending in the front-rear direction, and constitutes a first sliding groove 23 that slides the inner slide portion 22 provided on the lower inner side of the slider 12. .

The second resin rail 20 is open toward the right side in the left-right direction in a cross-sectional view. The second resin rail 20 is fitted to the second metal rail base material 17 so that the outer surface of the second resin rail 20 substantially contacts the inner surface of the second metal rail base material 17. The second resin rail 20 is fixed to the second metal rail base material 17 by rivets 21. The 2nd resin rail 20 and the 2nd metal rail base material 17 are good also as a structure fixed by giving an engagement shape mutually. The groove-like space defined by the inner surface of the second resin rail 20 is such that the side close to the opening of the groove-like space (the right side in the left-right direction) slides the outer slide portion 24 provided on the lower outer side of the slider 12. The side that forms the second sliding groove 25 and is away from the opening of the groove-like space constitutes a belt guide portion 26 that holds the rack belt 10 and guides its movement in the front-rear direction. There is a step difference between the second sliding groove 25 and the belt guide portion 26, and the belt guide portion 26 is wider in the vertical direction. The portion that defines the second sliding groove 25 is provided on the right side (right side in the left-right direction) of the right end of the lip wall 17c of the second metal rail base member 17. In addition, on the upper surface and the lower surface of the outer surface of this portion, a lightening 27 is formed, respectively.

Further, as shown in FIG. 2, the second resin rail 20 includes an elevating guide portion 29 in which an elevating guide groove 28 for guiding the elevating of the panel bracket 13 is formed. The raising / lowering guide part 29 is injection-molded integrally with the main body part 30 that forms the second sliding groove 25 and the belt guide part 26. Alternatively, the main body 30 may be extruded and the elevating guide 29 may be formed separately from the main body 30 and the two may be combined. The raising / lowering guide part 29 guides the rear raising / lowering guide part 29a which guides the rear guided piece 31a provided in the vicinity of the rear end of the panel bracket 13, and the front guided piece 31b provided on the front end side of the panel bracket 13. And a front raising / lowering guide portion 29b. The panel bracket 13 tilts so that the rear end side moves up and down around the slider portion 32 formed on the front end side with respect to the front guided piece 31b.

The rear raising / lowering guide part 29a guides the raising and lowering of the panel bracket 13 in the vicinity of the closed position. The rear lifting guide groove 28a provided in the rear lifting guide part 29a communicates with the second sliding groove 25 and extends in the vertical direction. The front-rear direction guide groove 28a has a front-rear width that is substantially equal to the front-rear direction width of the rear guided piece 31a on the lower end side communicating with the second sliding groove 25, and the upper end side is set slightly wider than the lower end side. In this case, the rear guided piece 31a is allowed to shift in the front-rear direction. The rear lifting guide portion 29 a does not narrow the vertical width of the second sliding groove 25 on the lower end side, but extends upward from the upper surface of the main body portion 30 of the second resin rail 20 on the upper end side. The upper surface of the upwardly extending portion is curved or inclined so as to go upward as it goes forward, and the impact piece 33 provided on the rear end side of the panel bracket 13 impacts and slides. It constitutes 34 for the time being. The abutting surface 34 is preferably curved so as to be concave in the front-rear direction. When the sunroof panel 6 is displaced to the closed position as the panel bracket 13 is moved forward from the position where the front side of the opening 5 is opened, the impact piece 33 strikes the impact surface 34 and slides. Sound is reduced.

The front lifting guide portion 29b guides the entire lifting operation of the panel bracket 13 when the sunroof panel 6 is displaced between the closed position and the rear tilted position. The front lifting guide groove 28b communicates with the second sliding groove 25 and extends in the vertical direction. Further, the front elevating guide groove 28b is configured such that when the rear portion of the panel bracket 13 is raised, the slider portion 32 slightly slides backward, and when the rear portion of the panel bracket 13 is lowered, the slider portion 32 is slightly forward. As it slides, it curves so that it goes back as it goes up. The front / rear direction width of the front lifting guide groove 28b is substantially constant so that both front and rear ends of the front guided piece 31b are in sliding contact with the front lifting guide groove 28b when the rear portion of the panel bracket 13 is lifted / lowered. The upper end of the front raising / lowering guide part 29 b extends upward from the upper surface of the main body part 30 of the second resin rail 20. Further, the front elevating guide portion 29b forming the front elevating guide groove 28b has the second sliding only the front side portion of the front elevating guide groove 28b so as to restrict the forward movement of the front guided piece 31b. It extends downward so as to enter the groove 25, and restricts forward movement of the panel bracket 13 at the rising start position.

As shown in FIG. 3, the first resin rail 19 and the second resin rail 20 are separated from each other in the left-right direction. The assembly of the guide rail 9 is performed by attaching the first resin rail 19 to the first metal rail base material 16 and attaching the second resin rail 20 to the second metal rail base material 17, and then the first metal rail base material 16 and the first metal rail base material 16. This is done by joining two metal rail base materials 17 together. The first resin rail 19 can be attached to the first metal rail base 16 from the left-right direction, not from the front-rear direction, which is the long direction, because there is a work space in the left-right direction. 19 can be easily fitted to the first metal rail base 16 and fixed by the rivets 21. The same applies to the attachment of the second resin rail 20 to the second metal rail base material 17.

As shown in FIGS. 1 and 2, the pair of rack belts 10 slide back and forth within the belt guide portion 26 of the resin guide rail 8 simultaneously by the drive motor 11. The slider 12 is fixed to the rack belt 10 and slides back and forth on the resin guide rail 8 as the rack belt 10 slides. Instead of the rack belt 10, a push-pull cable may be used.

As shown in FIG. 3, the slider 12 includes an inner slide portion 22 that slides in the first slide groove 23 of the first resin rail 19, and a second slide of the second resin rail 20 that is connected to the inner slide portion 22. An outer slide portion 24 that slides in the moving groove 25, a first side wall 35 whose lower end side is fixed to the inner slide portion 22 and whose upper end side extends above the guide rail 9, and lower end side is fixed to the outer slide portion 24. The second side wall 36 whose upper end side extends above the guide rail 9, and the first side wall 35 and the pin 37 whose both ends are supported on the upper part of the second side wall 36 are provided. The first side wall 35 and the second side wall 36 have a flat plate shape orthogonal to the left-right direction in the upper part, are opposed to each other with the panel bracket 13 interposed therebetween, and the lower part is refracted so as to be substantially orthogonal to the upper part. The inner slide part 22 and the outer slide part 24 are joined. The inner slide part 22, the outer slide part 24, the first side wall 35, and the second side wall 36 are made of resin or metal, respectively. The inner slide part 22 and the outer slide part 24 are preferably made of resin. The pin 37 made of metal is disposed above the guide rail 9 and slidably penetrates a guide groove 38 provided in the panel bracket 13. The pin 37 and the guide groove 38 constitute the cam mechanism 14.

The main body 39 of the panel bracket 13 includes a flat plate-like main wall 40 that is substantially orthogonal to the left-right direction, and a flange 41 that is provided so as to extend leftward (outside) from the edge of the main wall 40. The main body 39 is made of metal, and a guide groove 38 is formed in the main wall 40. The guide groove 38 extends in the front-rear direction while curving up and down. The panel bracket 13 further includes a rear guided piece 31a, a front guided piece 31b, a slider portion 32, and an abutting piece 33. The rear guided piece 31 a and the front guided piece 31 b protrude to the left so as to be received in the second sliding groove 25 of the second resin rail 20. The abutting piece 33 is located behind and above the rear guided piece 31a and protrudes to the left so as to be disposed above the second resin rail 20. The slider portion 32 is provided below the front end portion of the flange 41, and the position in the left-right direction is set so that the lower surface can contact the second resin rail 20. The lower surface of the slider portion 32 is curved back and forth so as to protrude downward. The rear guided piece 31a, the slider part 32, and the abutting piece 33 are made of resin and attached to the left side of the main body 39 (inward in the vehicle direction). The front guided piece 31b is made of a metal integral with the main body 39 and protrudes leftward from the main body 39.

The cam mechanism 14 includes a pin 37 and a guide groove 38. In the rear part of the sliding range of the slider 12 (see FIG. 6), the pin 37 is locked to the rear end of the guide groove 38, and the panel bracket 13 moves along the guide rail 9 in the front-rear direction together with the slider 12. At this time, in order to reduce the frictional resistance, the abutting piece 33 is separated from the guide rail 9 and either one or both of the rear guided piece 31a and the front guided piece 31b do not slide on the resin guide rail 8. Is preferred. For example, when the panel bracket 13 is slid, the upper surface of the rear guided piece 31a is in sliding contact with the second sliding groove 25 of the second resin rail 20 to restrict the tilt of the panel bracket 13 and the front guided piece 31b. Is received in the second sliding groove 25 but is separated from the wall surface thereof, and the abutting piece 33 is separated from the upper surface of the second resin rail 20. Since the slider portion 32 is arranged so that the lower surface thereof is in sliding contact with the resin guide rail 8, the slide movement of the panel bracket 13 is stabilized, and the contact of the slider portion 32 with the metal guide rail 7 is prevented to wear. Is reduced. When the panel bracket 13 slides, the lower surface of one or both of the rear guided piece 31a and the front guided piece 31b slides in the second sliding groove 25, and the slider part 32 moves to the guide rail 9. You may set so that it may space apart from. At the front part of the sliding range of the slider 12 (see FIG. 5), the panel bracket 13 does not substantially move in the front-rear direction, and the pin 37 slides in the guide groove 38. For this reason, the panel bracket 13 tilts so that the rear part moves up and down as an axis on which the slider part 32 rolls.

Next, the operation of the sunroof device 1 will be described with reference to FIGS. In the following description of the function and effect, each pair of left and right members refers to both unless otherwise specified. 4 is a cross-sectional view taken along the line IV-IV of FIG. 1, that is, a cross-sectional view taken along the boundary between the second sliding groove 25 of the second resin rail 20 and the belt guide portion 26. Indicates closed position. FIG. 5 shows a position where the sunroof panel 6 starts to slide backward in the same cross section as FIG. 4, and FIG. 6 shows a position where the sunroof panel 6 tilts up in the same cross section as FIG.

As shown in FIG. 4, in the closed position, the pin 37 of the slider 12 is slightly separated from the rear end of the guide groove 38. When the sunroof panel 6 is slid rearward to open the opening 5 of the roof 3 from the front side, the user drives the drive motor 11 so that the slider 12 moves rearward. Since the rear end of the front guided piece 31b is locked to the front elevating guide portion 29b from the rear, the panel bracket 13 does not move in the front-rear direction, and the pin 37 of the slider 12 moves backward in the guide groove 38. To slide. The guide groove 38 is directed upward in the vicinity of the rear end toward the rear, and the slider 12 is restricted from moving in the vertical direction by the first sliding groove 23 and the second sliding groove 25 of the resin guide rail 8. Therefore, the panel bracket 13 tilts so that the rear part is lowered. At this time, the curved lower surface of the slider portion 32 rolls on the bottom surface of the metal guide rail 7, and the rear guided piece 31a is lowered while being guided by the rear lifting guide portion 29a. As this descends, the sunroof panel 6 attached to the panel bracket 13 moves downward relative to the outer layer panel of the roof 3.

As shown in FIG. 5, the front guided piece 31b is released from the locking by the front lifting guide part 29b and is received in the second sliding groove 25, and the rear guided piece 31a passes through the rear lifting guide groove 28a. When the pin 37 is received by the second sliding groove 25 and the pin 37 reaches the rear end of the guide groove 38, the panel 37 moves backward by pulling the panel bracket 13 backward. Then, the sunroof panel 6 moves rearward and is accommodated between the outer layer panel of the roof 3 and the interior panel, and the opening 5 is opened from the front side.

When closing the opening 5 opened by the sliding movement of the sunroof panel 6, the user drives the drive motor 11 so that the slider 12 moves forward. Since the rear guided piece 31a is in sliding contact with the second sliding groove 25 to restrict the tilt of the panel bracket 13, the pin 37 pushes the inclined front surface near the rear end of the guide groove 38, so that the panel bracket 13 is moved forward. Move to. When the front guided piece 31b comes into contact with the front lifting guide portion 29b, the forward movement of the panel bracket 13 is restricted. At this time, the abutting piece 33 of the panel bracket 13 abuts against the curved abutting surface 34 of the rear elevating guide portion 29a and comes into sliding contact, so that the collision between the front guided piece 31b and the front elevating guide portion 29b is alleviated. The beating sound is reduced. Thereafter, the pin 37 slides forward in the guide groove 38 and raises the panel bracket 13 until the sunroof panel 6 closes the opening 5. The drive motor 11 stops when the sunroof panel 6 returns to the closed position shown in FIG.

When the rear portion of the sunroof panel 6 is tilted up from the closed position to open the opening 5, the user drives the drive motor 11 so that the slider 12 moves forward. Since the front guided piece 31b is locked to the front lifting guide portion 29b from the front, the panel bracket 13 is restricted from moving forward. Therefore, the pin 37 slides forward in the guide groove 38. Since the guide groove 38 is curved so that the front end side is positioned below the rear end side, the panel bracket 13 tilts with the slider portion 32 as an axis so that the rear portion is raised. Therefore, when the rear portion of the sunroof panel 6 is tilted up and the pin 37 reaches the front end of the guide groove 38, the sunroof panel 6 reaches the tilt-up position shown in FIG.

When returning the sunroof panel 6 from the tilt-up position to the closed position, the user drives the drive motor 11 so that the slider 12 moves backward. At this time, since the front guided piece 31b is locked to the front lifting guide portion 29b from the rear, the panel bracket 13 is restricted from moving rearward. Therefore, the pin 37 moves the guide groove 38 forward, and tilts the panel bracket 13 so that the rear part thereof is lowered. The drive motor 11 stops when the sunroof panel 6 returns to the closed position shown in FIG.

The resin guide rail 8 forms a first sliding groove 23 and a second sliding groove 25 that slidably support the slider 12 and the panel bracket 13, and a lifting guide for supporting the panel bracket 13 to be tiltable. A groove 28 is formed. Therefore, the metal guide rail 7 does not need to have a complicated shape for sliding or tilting the slider 12 and the panel bracket 13, and is attached for the purpose of reinforcing the rigidity of the guide rail 9. Therefore, the metal guide rail 7 can be made into a simple shape that can be formed by bending. In addition, the first slide groove 23 and the second slide groove 25 are formed in a single stage, and the shape of the metal guide rail 7 is simplified because the slider 12 and the panel bracket 13 slide in the same groove. Contributing to

Moreover, since the main body part 30 and the raising / lowering guide part 29 which form the 2nd sliding groove 25 are integrally molded, the 2nd resin rail 20 becomes easy to assemble. Furthermore, since the metal guide rail 7 and the resin guide rail 8 are composed of members divided into left and right, the first resin rail 19 and the second resin rail 20 are connected to the first metal rail not from the longitudinal direction but from the left and right directions. Since it can attach to the base material 16 and the 2nd metal rail base material 17, an assembly operation becomes easy.

Next, a modified embodiment will be described with reference to FIG. FIG. 7 is a cross-sectional view of the guide rail 109 disposed on the left side of the opening 5 (see FIG. 1) at the same position as FIG. In the following description, parts having the same structure and operation as those of the above embodiment are denoted by the same reference numerals, and the description thereof is omitted. Similarly to the above embodiment, in the following description, a portion disposed on the left side of the opening 5 will be described. About the part arrange | positioned at the right side of the opening 5, the description on either side becomes reverse. The modified embodiment differs from the above embodiment in that there is no member corresponding to the first resin rail 19 of the above embodiment.

The guide rail 109 includes a metal guide rail 107 and a resin guide rail 108 attached to the metal guide rail 107, but the resin guide rail 8 includes only the second resin rail 20. Therefore, the inner slide portion 22 of the slider 12 slides with respect to the first metal rail base material 116 of the metal guide rail 107 instead of the resin guide rail 108. The first metal rail base material 116 includes a lower wall 116a, a side wall 116b erected at the right end of the lower wall 116a, and a lip wall 116c extending leftward at the upper end of the side wall 116b. On the left side of the lower wall 116a, a plurality of tabs 116d extending leftward and joined to the second metal rail base material 17 are formed. A first sliding guide portion 123 on which the inner slide portion 22 of the slider 12 slides is defined by the lower wall 116a, the side wall 116b, and the lip wall 116c. The lower wall 116 a may have a step formed between a portion that defines the first sliding guide portion 123 and a portion that is joined to the second metal rail base material 17. The inner slide portion 22 of the slider 12 is preferably made of resin, and a lubricant such as grease is preferably used in order to reduce wear due to sliding with the first metal rail base material 116.

This is the end of the description of the specific embodiment, but the present invention is not limited to the above-described embodiment, and can be widely modified. For example, the panel bracket may be slid and tilted without using a slider. The metal guide rail may be formed from one or three or more base materials, the resin guide rail may be formed from one resin rail integrally formed, and the first and second resin rails are two. You may assemble from the above members. Moreover, the guide structure according to the present invention can be applied not only to a sunroof of a vehicle but also to a sunroof of a building such as a house.
