Description

  The present invention relates to a retractable hard panel roof opening and closing device.

  Conventionally, various types of retractable hard panel roof opening / closing devices are known. For example, in Patent Document 1, the roof has a structure that can be divided into three parts of a first panel (30), a second panel (32), and a third panel (34) in the vehicle longitudinal direction. When these first to third panels are fully opened (when the roof is retracted), the first panel is in the retracted position with the top and bottom as it is, the second and third panels are in the retracted position with the top and bottom turned upside down, The second panel and the first panel are stacked from bottom to top (in the height direction). The linkage between the second and third panels at the time of opening and closing is through a link (76).

  Moreover, in patent document 2, the roof has a structure which can be divided | segmented into three, a 1st panel (2), a 2nd panel (3), and a 3rd panel (4) in the vehicle front-back direction. The storage posture and the stacking order of these first to third panels are the same as described above. The linkage between the second and third panels at the time of opening and closing is through the link (16).

  Furthermore, in Patent Document 3, the roof has a structure that can be divided into three parts, a first panel (6), a second panel (7), and a third panel (8) in the vehicle longitudinal direction. When the first to third panels are fully opened, they are stacked in the same order as described above in the retracted position as they are. The linkage between the second and third panels at the time of opening and closing is through the link (16).

  Furthermore, in Patent Document 4, the roof has a configuration that can be divided into three parts of a first panel (3), a second panel (4), and a third panel (5) in the vehicle longitudinal direction. When the first to third panels are fully opened, the first and second panels are stacked in the same order as described above, with the first panel and the second panel stored in the upright position and the third panel stored in the upright position. Here, the space required in the vehicle front-rear direction for storing the third panel is reduced by moving the third panel separately from the other panels.

In Patent Document 5, the roof has a configuration that can be divided into at least two panels (5, 4) in the vehicle front-rear direction, and is laminated in various retracted postures when fully opened. Here, the panels are linked by a combination of a link and a gear.
US Pat. No. 6,695,386 B1 (FIGS. 1-6) European Patent No. 0 835 778 B1 (FIGS. 1-8) US Pat. No. 6,336,673 B1 (FIGS. 1-4) German Patent Invention No. 101 28 322 C2 (FIG. 1-12) International Publication No. 01/40007 A1 Pamphlet (Figure 1-11)

  By the way, in Patent Document 1, it is necessary to increase the space required in the vehicle front-rear direction for the storage of the third panel including the allowance of the operation locus, and the luggage space (luggage space) is reduced. Become. This is because the pivot shaft of the link (80, 82) that defines the movement of the third panel is fixed to the body (14) via the bracket (84).

  Also in Patent Document 2, the space required in the vehicle front-rear direction for storing the third panel is inevitably increased as described above. This is because the pivot axis (13) of the third panel and the pivot axis (17) of the link (16) are fixed to the body.

  Further, even in Patent Document 3, the space required in the vehicle front-rear direction for storing the third panel is inevitably increased as described above. This is because the pivot shaft (15) of the third panel is fixed to the body.

On the other hand, in Patent Document 4, there is no mechanism for interlocking the second and third panels at the time of opening and closing, and the third panel must be moved independently.
Moreover, in patent document 5, it is not the structure which connects a 2nd panel (5) and a 3rd panel (4) directly, but has a structure provided with the complicated mechanism in the panel side.

  An object of the present invention is to further reduce the space required in the vehicle front-rear direction for storage by reducing the operation trajectory of the third panel when storing the roof portion of the vehicle, and to suitably use the luggage space. An object of the present invention is to provide a retractable hard panel roof opening and closing device that can be secured.

  The invention according to claim 6 is the retractable hard panel roof opening and closing device according to any one of claims 2 to 5, wherein one side end of one of the first and second links is: The link gear is rotatably supported by the link so that the link gear is interposed between the link and the link, and the link is bent so as to be separated from one of the first and second links. Thus, the gist of the present invention is to form an arrangement space for the base gear and the idle gear in which interference with any one of the first and second links is avoided.

  A seventh aspect of the present invention is the retractable hard panel roof opening and closing device according to any one of the first to sixth aspects, wherein the link has a second end rotatably supported by the first panel. The gist of the invention is that it includes a driven link that is fixed to the second panel and has one end and another end rotatably supported by the vehicle body and the first panel.

  As described above in detail, in the first aspect of the present invention, the first and second links form a four-bar rotating chain together with the third panel and the link. Therefore, in a state in which one side end portion of either the first link or the second link rotates with respect to the link as the link is rotated by switching the means, the operation locus of the third panel is It is determined by the rotation position of the link and the operation of the four-joint rotation chain in accordance with the rotation position of one end of one of the first and second links with respect to the link corresponding to the rotation position of the link. .

  In addition, when one of the first and second links does not rotate with respect to the link due to the switching of the means, the operation trajectory of the third panel is It is determined only by the rotational position of the link by stopping the operation of the four-bar rotation chain.

  As described above, the movement trajectory of the third panel corresponding to the rotation position of the link is rotated with one end of one of the first and second links rotating with respect to the link. The degree of freedom (flexibility) can be increased by switching depending on whether or not to do so. Therefore, by reducing the operation trajectory of the third panel when storing the roof portion (full opening of the first to third panels), the space required in the vehicle front-rear direction for storage is reduced, A cargo space can be suitably secured.

  In the invention according to claim 2 or 3, the first and second links constitute a four-bar rotating chain together with the links and the third panel. Therefore, the range of the link from the rotational position corresponding to the fully closed state of the first, second and third panels to the predetermined rotational position, and the first, second and third panels fully opened from the predetermined rotational position. In a state where one side end of one of the first and second links rotates with respect to the link in accordance with the rotation of the link in any one of the range of rotation positions of the link corresponding to the state, The movement trajectory of the third panel is 4 according to the rotational position of the link and the rotational position of one end of one of the first and second links with respect to the link corresponding to the rotational position of the link.

  Further, the range of the link from the rotational position corresponding to the fully closed state of the first, second, and third panels to a predetermined rotational position, and the first, second, and third panels from the predetermined rotational position are fully opened. In a state where the rotation of one side end of one of the first and second links with respect to the link in the other of the rotation position ranges of the link corresponding to the state is restricted. The movement trajectory of the third panel is determined only by the rotational position of the link by stopping the movement of the four-bar rotation chain. At this time, the link rotates while sliding the second engagement portion with respect to the first engagement portion.

  As described above, the movement trajectory of the third panel corresponding to the rotation position of the link is rotated with one end of one of the first and second links rotating with respect to the link. The degree of freedom (flexibility) can be increased by switching depending on whether or not to do so. Therefore, by reducing the operation trajectory of the third panel when storing the roof portion (full opening of the first to third panels), the space required in the vehicle front-rear direction for storage is reduced, A cargo space can be suitably secured.

  According to a fourth aspect of the present invention, the gear part and the second engaging part are formed in different angular ranges of the disk part of the idle gear. That is, the gear portion and the second engaging portion are arranged and formed by overlapping the positions in the axial direction in the disk portion. Accordingly, the first engagement portion that engages with the second engagement portion and the link gear that meshes with the gear portion are also arranged so that the positions in the axial direction are overlapped with each other. Therefore, the arrangement space in the axial direction of the base gear, the idle gear, and the link gear can be reduced.

  In the invention according to claim 5, the engagement of the first and second engaging portions is extremely simple by the fan shape and the bay-shaped notch of the disc portion in which the outer peripheral surface of the fan shape is in sliding contact. Can be performed with a simple structure.

Arranged in the arrangement space where interference with either one of the two links is avoided. In this way, the link is bent so as to be separated from one of the first and second links, and the base gear and the idle gear are disposed. Space can be reduced.

  In the invention according to claim 7, the link and the driven link constitute a four-joint rotating chain together with the vehicle body and the first panel. Accordingly, the motion trajectory of the first panel is determined by the motion of the four-bar rotation chain corresponding to the rotational position of the link. On the other hand, the motion trajectory of the second panel is determined by the rotational position of the link. Thus, the degree of freedom (flexibility) can be increased by determining the movement trajectories of the first and second panels in different modes.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1A is a side view of a non-retracted state (roof fully closed state) schematically showing an automobile as a vehicle to which the present invention is applied, and FIG. It is an enlarged view of a state. As shown in the figure, a vehicle body 1 of an automobile has a so-called coupe type shape in which a rear portion of a roof 2 as a roof portion thereof is gently inclined. A trunk 3 that forms a luggage space (luggage space) S1 is provided at the rear of the vehicle body 1. The luggage space S1 of the trunk 3 is partitioned from the front storage space S2 by a trim (lining) 4 as a partition member. This storage space S2 is for storing the roof 2 behind the vehicle.

  The opening of the cargo space S1 is closed by a luggage panel (trunk lid) 5. The luggage panel 5 is rotatably supported on the vehicle body 1 by a hinge 6 provided at the rear portion of the vehicle body 1. When the roof 2 is retracted, the luggage panel 5 rotates around the hinge 6 in the clockwise direction shown in the figure so that the front of the vehicle opens (opens forward) in order to avoid interference with the roof 2.

  The roof 2 includes a first panel 11 that forms a front part, a second panel 12 that forms an intermediate part, and a third panel 13 that forms a rear part. That is, the roof 2 has a configuration that can be divided into three parts, that is, first to third panels 11 to 13 in the longitudinal direction of the vehicle.

  As shown in FIG. 1, in the fully closed state of the first to third panels 11 to 13, the front end 11a of the first panel 11 is abutted against the window frame 1a of the front window, and the rear end 11b is the second end. The two panels 12 are abutted against the front end 12a. The rear end 12 b of the second panel 12 is abutted against the front end 13 a of the third panel 13, and the rear end 13 b of the third panel 13 is abutted against the luggage panel 5.

  The first to third panels 11 to 13 are opened / closed by the opening / closing mechanism 14, thereby changing in a range from a fully closed state to a fully open state (stored state). The opening / closing mechanisms 14 are arranged in pairs on both sides in the width direction of the vehicle (the back side and the near side perpendicular to the paper surface in FIG. 1), and the one opening / closing mechanism 14 will be described below as a representative.

  The opening / closing mechanism 14 includes a base 21 fixed to the vehicle body 1, a driven link 22, a rail link 23 as a link, a first link 24, a second link 25, and the means shown in FIG. The base gear 26, the idle gear 27, and the link gear 28 are provided.

  The follower link 22 has one end 22 a rotatably supported on the base 21 by a shaft 31 and the other end 22 b rotatably supported by the first panel 11 by a shaft 32. The rail link 23 has one end 23a rotatably supported on the base 21 by a shaft 33 and the other end 23b rotatably supported by the first panel 11 by a shaft 34. The shaft 33 is disposed behind the vehicle with respect to the shaft 31. The rail link 23 is fixed to the second panel 12. The rail link 23 is rotationally driven around an axis 33 by an actuator (not shown).

  Here, the rail link 23 and the follower link 22 together with the base 21 and the first panel 11 constitute a four-node rotating chain. Therefore, the motion trajectory (posture) of the first panel 11 is determined by the motion of the four-joint rotation chain according to the rotational position of the rail link 23. On the other hand, the motion trajectory (posture) of the second panel 12 is determined by the rotational position of the rail link 23. The first and second panels 11 and 12 are opened and closed along their respective operation trajectories corresponding to the rotational position of the rail link 23. In FIG. 1, the operation trajectories of the shaft 32 and the shaft 34 corresponding to the rotational position of the rail link 23 are also shown by curves C1 and C2, respectively.

  The first link 24 has one end 24 a rotatably supported on the rail link 23 by a shaft 35, and the other end 24 b is rotatable by the shaft 36 on the mounting portion 13 c of the third panel 13. It is supported by. The second link 25 has one end portion 25a rotatably supported on the rail link 23 by a shaft 37, and the other end portion 25b rotatable by a shaft 38 on the attachment portion 13c of the third panel 13. It is supported by. In the fully closed state of the first to third panels 11 to 13 shown in FIG. 1, the shaft 37 is arranged behind the vehicle 35 relative to the shaft 35.

  Here, the first and second links 24 and 25 together with the rail link 23 and the third panel 13 (attachment portion 13c) constitute a four-node rotation chain. However, the one end 24 a of the first link 24 rotates around the shaft 35 with respect to the rail link 23 as the rail link 23 rotates, and the rail link 23 regardless of the rotation of the rail link 23. 23 to the state where it does not rotate around the axis 35 with respect to 23 in the manner described below. Accordingly, the movement locus (posture) of the third panel 13 is switched depending on whether or not the one end 24a of the first link 24 rotates relative to the rail link 23 as the rail link 23 rotates. That is, when the one end 24 a of the first link 24 rotates with respect to the rail link 23 as the rail link 23 rotates, the operation locus of the third panel 13 is the rotation of the rail link 23. It is determined by the position and the operation of the four-node rotation chain according to the rotational position of the one end 24a of the first link 24 with respect to the rail link 23 corresponding to the rotational position of the rail link 23. Further, in a state where the rotation of the one end 24a of the first link 24 relative to the rail link 23 accompanying the rotation of the rail link 23 is restricted, the operation locus of the third panel 13 is a four-node rotation chain. The operation is stopped and the posture of the four-node rotation chain, that is, the relative position of the third panel 13 with respect to the rail link 23 is maintained, and therefore, it is determined only by the rotational position of the rail link 23. Then, the third panel 13 is opened and closed along the corresponding operation locus.

  FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. As shown in the figure, one end 24a of the first link 24 is rotatably supported by the rail link 23 so that the link gear 28 is interposed between the first link 24 and the rail link 23. Yes. The rail link 23 is bent at step portions 23c and 23d so as to be separated from the first link 24 to one side (right side in FIG. 6). Thus, the rail link 23 forms an arrangement space S for the base gear 26 and the idle gear 27 in which interference with the first link 24 is avoided.

  The base gear 26 is fixed to the base 21 concentrically with the center of rotation (the shaft 33) of the rail link 23 with respect to the base 21. The base gear 26 includes a cam 41 and a first gear portion 42 as first engaging portions. The base gear 26 is joined to the base 21 in such a manner that the end surface on the one side in the axial direction of the first gear portion 42 (the right side in FIG. 6) abuts on the end surface on the arrangement space S side of the base 21. The cam 41 is disposed on the other axial side of the first gear portion 42 (left side in FIG. 6).

  As shown in FIG. 1 (b), the first gear portion 42 is formed as a sector gear with teeth engraved only on the outer peripheral surface of a predetermined angle range, and the range excluding the predetermined angle range is as follows. A sectoral portion 42a having an outer diameter equivalent to the diameter of the root circle of the sector gear is formed. The cam 41 is formed in a fan shape corresponding to an angle range different from the predetermined angle range. The cam 41 is formed in an angular range that is continuous with a boundary position on one side of the teeth of the first gear portion 42 and the sectoral portion 42a (the clockwise direction in FIG. 1B). The outer diameter of the cam 41 is set smaller than the outer diameter of the first gear portion 42 (fan-shaped portion 42a).

  The idle gear 27 is rotatably supported on the rail link 23 by a shaft 39. The idle gear 27 has a second gear portion 43 and a disc portion 44. The idle gear 27 is arranged in such a manner that the end face on the axial direction one side (the right side in FIG. 6) of the second gear portion 43 faces the end face on the arrangement space S side of the rail link 23. The portion 44 is disposed on the other axial side of the second gear portion 43 (left side in FIG. 6).

  As shown in FIG. 6, the second gear part 43 is arranged so that the position in the axial direction overlaps with the first gear part 42. As shown in FIG. 1 (b), the second gear portion 43 is formed as a sector gear with teeth engraved only on the outer peripheral surface of a predetermined angle range, and the range excluding the predetermined angle range is as follows. A sector portion 43a having an outer diameter equivalent to the diameter of the tip circle of the sector gear is formed. The second gear portion 43 is connected to the rail link 23 from the rotational position P1 of the rail link 23 corresponding to the fully closed state of the first to third panels 11 to 13 shown in FIG. The first gear portion 42 is engaged with the first gear portion 42 in a range up to a predetermined rotational position P2 that is rotated around the predetermined angle θ (see FIG. 4) in the clockwise direction. Accordingly, in the range of the rotational positions P1 to P2 of the rail link 23, the second gear portion 43 (idle gear 27) rotates around the first gear portion 42 as the rail link 23 rotates. While revolving, it also rotates (rotates).

  As shown in FIG. 6, the disc portion 44 has an outer diameter larger than the outer diameter of the second gear portion 43, and is arranged so that the position in the axial direction overlaps with the cam 41. ing. As shown in FIG. 1B, the disc portion 44 is formed with a gear portion 45 and a cam surface 46 as a second engaging portion in different angular ranges. The cam surface 46 is formed by being cut out in a bay shape radially inward from the outer peripheral surface of the disk portion 44 in the radially outer range of the second gear portion 43. The cam surface 46 is in a range from the rotational position P1 of the rail link 23 to the predetermined rotational position P2 corresponding to the fully closed state of the first to third panels 11 to 13 shown in FIG. The engagement with the cam 41 is disconnected.

  Further, the cam surface 46 is located within the range of the rotation position P3 of the rail link 23 (see FIG. 5) corresponding to the fully open state of the first to third panels 11 to 13 from the predetermined rotation position P2. Engage with. That is, the cam 41 is fitted to the cam surface 46 in the range of the rotational positions P2 to P3 of the rail link 23. Accordingly, the idle gear 27 is prevented from rotating by the cam 41 on the cam surface 46, so that the rotation associated with the rotation of the rail link 23 is restricted. At this time, the cam surface 46 is fitted to the cam 41 so that the outer peripheral surface of the cam 41 comes into sliding contact with the rotation of the rail link 23. Further, the meshing of the second gear part 43 with the first gear part 42 is cut off. Therefore, the rotation restriction of the idle gear 27 does not affect the rotation of the rail link 23. The outer peripheral surface of the fan-shaped portion 42a of the base gear 26 (first gear portion 42) comes into sliding contact with the fan-shaped portion 43a of the idle gear 27 (second gear portion 43) as the rail link 23 rotates.

  As shown in FIG. 6, the link gear 28 interposed between the rail link 23 and the first link 24 is overlapped with the disk portion 44 (gear portion 45) in the axial direction. Has been placed. The link gear 28 is rotatably supported by the rail link 23 concentrically with the rotation center (shaft 35) of the one end 24a of the first link 24 with respect to the rail link 23. The link 24 is joined to the first link 24 in such a manner that it abuts against the end surface of one side in the axial direction (the right side in FIG. 6). The link gear 28 meshes with the gear portion 45 of the idle gear 27.

  Therefore, the link gear 28 rotates as the idle gear 27 (gear portion 45) rotates. That is, the link gear 28 is moved from the rotational position P1 of the rail link 23 corresponding to the fully closed state of the first to third panels 11 to 13 where the idle gear 27 rotates as the rail link 23 rotates. In the range up to the predetermined rotation position P2, as the rail link 23 rotates, it rotates around the shaft 35 together with the one end 24a of the first link 24.

  Further, the link gear 28 corresponds to the fully opened state of the first to third panels 11 to 13 from the predetermined rotation position P2 where the rotation of the idle gear 27 with the rotation of the rail link 23 is restricted. The rail link 23 is fixed to the rail link 23 together with the one end 24a of the first link 24 in a range up to the rotational position P3 of the rail link 23.

  Incidentally, when the cam 41 and the cam surface 46 are engaged, there is no rotation transmission between the gear portion 45 and the link gear 28. For this reason, since it is sufficient to form the gear portion 45 in an angle range of the disc portion 44 that requires at least rotation transmission between the gear portion 45 and the link gear 28, the disc portion 44 has an angle range different from the above. The cam surface 46 can be integrally formed.

  The link gear 28 is formed as a fan-shaped gear in which teeth are engraved only on the outer peripheral surface in a predetermined angle range related to the rotation transmission with the gear portion 45, but the tooth gear extends over the entire outer peripheral surface. A carved gear may be used.

  Here, as described above, the operation trajectory of the third panel 13 is switched depending on the presence or absence of the rotation of the one end 24a of the first link 24 with respect to the rail link 23 as the rail link 23 rotates. is there. Hereinafter, the relationship between the rotational position of the rail link 23 and the operation locus of the third panel 13 will be described with reference to FIGS. 2A shows the same rail from the rotational position (see FIG. 1) P1 of the rail link 23 corresponding to the fully closed state of the first to third panels 11 to 13 toward the predetermined rotational position P2. FIG. 2B is a side view schematically showing a state in which the link 23 is rotated around the shaft 33 in the illustrated clockwise direction, and FIG. 2B is an enlarged view showing the main part at this time. FIG. 3 (a) also shows that the rail link 23 is further rotated around the shaft 33 in the clockwise direction shown in the drawing from the rotational position of the rail link 23 shown in FIG. 2 (a) toward the predetermined rotational position P2. FIG. 3B is an enlarged view showing a main part at this time. Further, FIG. 4A is a side view schematically showing a state in which the rail link 23 is at the predetermined rotational position P2, and FIG. 4B is an enlarged view showing a main part at this time. . Further, FIG. 5A is a side view schematically showing a state in which the rail link 23 is in a rotational position P3 corresponding to the fully opened state (the retracted state of the roof 2) of the first to third panels 11-13. FIG. 5B is an enlarged view showing a main part at this time.

  As shown in FIGS. 1 to 3, when the rail link 23 is in the range from the rotational position P1 corresponding to the fully closed state of the first to third panels 11 to 13 to the predetermined rotational position P2, the rail As the link 23 rotates, the idle gear 27 rotates while rotating around the first gear portion 42 in the second gear portion 43. As a result, the link gear 28 rotates integrally with the one end 24 a of the first link 24. For example, the idle gear 27 rotates in the clockwise direction in the figure while rotating around the first gear part 42 in the second gear part 43 as the rail link 23 rotates in the clockwise direction in the figure. The link gear 28 rotates in the counterclockwise direction shown in the figure integrally with the one end 24a of the first link 24.

  Therefore, the movement locus of the third panel 13 is the rotational position of the rail link 23 and the rotational position of the one end 24a of the first link 24 relative to the rail link 23 corresponding to the rotational position of the rail link 23. And the operation of a four-bar rotation chain according to For example, the upper end 13d of the front end 13a of the third panel 13 is an operation locus indicated by a curve C31. Further, the rearmost end 13b of the third panel 13 is an operation locus indicated by a curve C311. The posture of the third panel 13 at this time changes so that the front end 13a (upper end 13d) rises above the opening of the storage space S2 in a state where the rear end 13b is disposed in the storage space S2.

  As shown in FIGS. 4 to 5, when the rail link 23 is in the range of the rotational position P3 corresponding to the fully closed state of the first to third panels 11 to 13 from the predetermined rotational position P2, The rotation of the idle gear 27 accompanying the rotation of the rail link 23 is restricted. Accordingly, the link gear 28 is fixed to the rail link 23 together with the one end 24 a of the first link 24.

  Accordingly, the movement locus of the third panel 13 is determined by the rotational position of the rail link 23 by holding the relative position of the third panel 13 with respect to the rail link 23 by fixing the first link 24 and the like. . For example, the upper end 13d of the front end 13a of the third panel 13 is an operation locus indicated by a curve C32. Further, the rearmost end 13b of the third panel 13 has an operation locus indicated by a curve C321. It goes without saying that these curves C311 and C321 are along a circumference centered on the axis 33. The posture of the third panel 13 at this time is introduced into the storage space S2 while being inverted upside down while the front end 13a (upper end 13d) is tilted backward while the rear end 13b is disposed in the storage space S2. It will be changed. Therefore, in a state where the rail link 23 is at the predetermined rotational position P2 shown in FIG. 4, a part of the third panel (the upper end 13d and the like) is disposed outside the front end of the trim 4.

  As described above, the first to third panels 11 to 13 are opened and closed along the corresponding operation trajectories. When the first to third panels 11 to 13 are fully opened (when the roof is stored), the first panel 11 is stored in the upright position, and the second and third panels 12 and 13 are stored upside down. In the posture, the third panel 13, the second panel 12, and the first panel 11 are stacked from the bottom to the top (in the height direction). In particular, the third panel 13 is stored in the storage space S <b> 2 in a storage posture in which the top and bottom are turned upside down almost directly below the position of the fully closed position along the above-described operation locus.

  As shown in FIGS. 1 to 5, the luggage panel 5 avoids interference with the roof 2 when the first to third panels 11 to 13 are opened and closed (for example, when the roof 2 is stored). Therefore, it is opened forward in the above-described manner and is closed after transition to the fully closed state or the fully open state.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, an operation trajectory of the third panel 13 corresponding to the rotation position of the rail link 23 is set to one of the first links 24 with respect to the rail link 23 as the rail link 23 rotates. The degree of freedom (flexibility) can be increased by switching depending on whether or not the side end 24a rotates. Therefore, the space required for storage in the vehicle front-rear direction (storage space) is reduced by further reducing the operation trajectory of the third panel 13 when storing the roof 2 (first to third panels 11 to 13). S2) can be reduced, and the cargo space S1 can be suitably secured.

  (2) In the present embodiment, the gear portion 45 and the cam surface 46 are formed in different angular ranges of the disc portion 44 of the idle gear 27, respectively. That is, the gear part 45 and the cam surface 46 are arranged and formed by overlapping the positions in the axial direction in the disk part 44. As a result, the cam 41 that engages with the cam surface 46 and the link gear 28 that meshes with the gear portion 45 are also arranged so that the positions in the axial direction overlap each other. Therefore, the arrangement space in the axial direction of the base gear 26, the idle gear 27, and the link gear 28 can be reduced.

  (3) In this embodiment, the cam 41 and the cam surface 46 are engaged with each other in a very simple structure by a fan shape and a bay-shaped notch of the disc portion 44 with which the fan-shaped outer peripheral surface is in sliding contact. Can be done.

  (4) In the present embodiment, the link gear 28 is interposed between the first link 24 and the rail link 23, and the base gear 26 and the idle gear 27 are connected to the first link 24. Arranged in the arrangement space S where interference is avoided. As described above, the rail link 23 is bent so as to be separated from the first link 24, and the base gear 26 and the idle gear 27 are disposed, thereby disposing the base gear 26, the idle gear 27, and the like. Space can be reduced.

  (5) In the present embodiment, the rail link 23 and the follower link 22 together with the base 21 and the first panel 11 constitute a four-node rotating chain. Accordingly, the motion trajectory of the first panel 11 is determined by the motion of the four-node rotation chain corresponding to the rotational position of the rail link 23. On the other hand, the movement locus of the second panel 12 is determined by the rotational position of the rail link 23. Thus, the degree of freedom (flexibility) can be increased by determining the movement trajectories of the first and second panels 11 and 12 in different modes.

(6) In the present embodiment, the third panel 13 can be stored in the storage space S2 in a storage posture in which the top and bottom are turned upside down almost directly below the fully closed position.
(7) In the present embodiment, since the driving force of the rail link 23 by the actuator is transmitted by mechanical connection via the first and second links 24 and 25 in the third panel 13, There is no need to separately provide a drive source for driving the panel 13.

  (8) In the present embodiment, since the second and third panels 12 and 13 do not receive interference with each other's operation, electronic control for driving them can be simplified, for example, position detection. Since no switch is required, the cost can be reduced and the reliability of the function can be improved.

In addition, you may change the said embodiment as follows.
The gear portion and the cam surface of the idle gear 27 may be individually molded while being shifted from each other in the axial direction.

The base gear 26 may be integrally formed with the base 21.
The link gear 28 may be integrally formed with the first link 24.
The link gear 28 may be fixed to the second link 25 and the presence / absence of the rotation of the one end portion 25a relative to the rail link 23 accompanying the rotation of the rail link 23 may be switched. At this time, the link gear 28 may be integrally formed with the second link 25.

  -In the said embodiment, in the range of the rotation position of the said rail link 23 of the first half, while the 1st-3rd panels 11-13 transition from a fully closed state to a fully open state, the 1st accompanying with rotation of the rail link 23. The rotation of the one end 24a of the first link 24 is restricted, and the rotation of the one end 24a of the first link 24 accompanying the rotation of the rail link 23 is allowed in the range of the rotation position of the rail link 23 in the latter half. May be.

The shapes of the rail link 23, the first and second links 24, 25, and the like are examples, and may be appropriately changed according to a required operation locus of the third panel 13.
The setting of the predetermined rotation position P2 at which the operation locus of the third panel 13 is switched is an example. The predetermined rotation position P2 can be easily changed by changing the engagement position of the cam 41 and the cam surface 46 related to the rotation restriction of the idle gear 27.

  A configuration (such as the base gear 26) for switching the presence or absence of rotation of the one end 24a of the first link 24 (or the one end 25a of the second link 25) relative to the rail link 23 as the rail link 23 rotates. It is an example.
