Description

  The present invention relates to a tonneau cover structure in a convertible top vehicle in which a roof can be stored in a trunk room.

  The tonneau cover in the convertible top car is arranged at the front part of the trunk room, and covers the space between the inside of the rear end of the roof and the seat provided at the rear part of the vehicle compartment when the roof is closed, and the roof is opened. The cover covers the space between the seat and the front end edge of the trunk lid to prevent the roof stored in the trunk room from being exposed to the outside, and various structures have been proposed.

  For example, Patent Document 1 includes a single tonneau cover, and the tonneau cover is horizontally extended in both the closed state and the open state of the roof, and this is moved to the passenger compartment side when the roof is opened and closed. The trunk lid is opened and the roof lid is opened to secure a space for the entrance and exit of the roof.

  Further, in Patent Document 2, the tonneau cover has a front / rear two-part structure composed of a front plate with a small depth near the passenger compartment and a rear plate with a large depth near the trunk, and the roof is closed and opened. The two plates extend forward and backward so as to form the same plane, while at the time of opening and closing the roof, the front plate is tilted downward at that position and stored closer to the passenger compartment, and the rear plate is This is stored by jumping upward at a position close to the passenger compartment, thereby ensuring a space for entering and exiting the roof.

  Furthermore, in Patent Document 3, the tonneau cover is moved closer to the passenger compartment by a second plate member that is pivotable in the vertical direction around the passenger compartment side end, and is moved closer to the trunk compartment by a link mechanism. And a front-and-rear two-part structure comprising a first plate member that can be rotated, and in the closed state and the open state of the roof, the first plate member is extended to the rear side and the rear side (trunk room side). In addition, the first plate member is extended to a state where the tip of the second plate member is placed on the upper side of the first plate member. On the other hand, when the roof is opened and closed, the first plate member is moved to the front position. While standing up, the second plate material is pushed up by the first plate material, and the two plate materials are stored close to the passenger compartment so as to secure the entrance / exit space for the roof.

Japanese Unexamined Patent Publication No. 2003-104065 (paragraphs “0022”, “0023”, “0038” to [0056], FIG. 1, FIG. 8 to FIG. 10).

  However, in the tonneau cover structure disclosed in Patent Document 1, the roof entry / exit space is limited to the size range of a single tonneau cover, and the enlargement of the tonneau cover size restricts the storage operation of the tonneau cover itself and the storage space. As a result, the tonneau cover entrance / exit space that can be secured is limited to a relatively small space. For this reason, roofs to which this tonneau cover structure can be applied are limited to those whose rear part has a steep inclination (in other words, the dimensions in the front-rear direction are short). For example, the rear part such as a coupe body has a gentle inclination. However, there was a problem that it was difficult to apply.

  Patent Document 2 or Patent Document 3 has been proposed to deal with such a problem of the tonneau cover having a single structure. However, in these cases, the tonneau cover has a two-part structure, so that the roof entrance / exit space can be expanded as compared to the one with a single structure, but the operating mechanism of the two-part structure tonneau cover is complicated. There was a problem of inviting up.

  Furthermore, the operation mode of the tonneau cover is limited to two modes: a mode in which two plates are closed together to form a substantially identical plane, and a mode in which the two plates are opened together to form a roof entrance / exit space. As mentioned above, “the original form requirement of tonneau cover” could not be satisfied, and there was room for improvement in this respect.

In other words, the “requirements on the original form of tonneau cover” are the following three forms:
The “first form” is a form in which the gap between the rear part of the seat and the front edge part of the trunk room is covered in the open state of the roof, and the maximum occupied area in the extended state of the tonneau cover is required. Is a form
The “second form” is a form for covering the gap between the rear portion of the seat and the rear end of the roof when the roof is closed, and the rear end of the roof is located immediately before the front edge of the trunk room. The occupied area in the extended state of the tonneau cover is a form that may be slightly smaller than the first form,
The “third form” is a form in which the roof is taken in and out of the trunk room in accordance with the opening / closing lid of the roof, and the area occupied by the tonneau cover is the smallest in order to secure the entrance / exit space. This is a required form.

  However, in the conventional tonneau cover having a two-part structure, as described above, there are only two forms: a spread form in which the two plate members constituting the tonneau cover are spread, and a one-off form in which these are moved closer to the passenger compartment. Since it is a configuration that cannot be taken, a large roof entrance / exit space can be secured in the one-off configuration, but in the extended configuration, the depth length of the entire tonneau cover is set to correspond to the above “first configuration”. The height of the rear end side of the tonneau cover must be set lower than the lower end of the roof, which inevitably causes a difference in height between the plate material close to the trunk room and the plate material close to the seat, resulting in a poor appearance. Occurs.

  Accordingly, in the present invention, the tonneau cover can be formed with a good appearance and a necessary width in both the closed state and the open state of the roof while ensuring a space for entering and exiting the roof. The purpose of the present invention is to provide a tonneau cover structure for a convertible top car that is excellent in terms of ensuring its original functions and convenience in use.

  In the present invention, the following configuration is adopted as a specific means for solving such a problem.

  In the first invention of the present application, in the tonneau cover 1 disposed in the front portion of the trunk room 53 of the convertible top vehicle, the tonneau cover 1 is composed of a first cover body 11, a second cover body 12, and a third cover body 13. While having a split structure, the first cover body 11 can be changed in position between a first attitude that is disposed near the front of the vehicle body and extends substantially horizontally and a second attitude that is flipped up to the front side of the vehicle body. The second cover body 12 has a first posture that extends substantially horizontally at the upper position, and a second posture that extends closer to the vehicle compartment 52 than the first posture and extends vertically at the lower position and the lower side. The position of the third cover body 13 can be changed between a third position extending substantially horizontally at the position, and the third cover body 13 extends substantially horizontally on the front side of the vehicle body from the first position. A second posture extending to the second position The posture can be changed between the third postures extending in the vertical direction below the posture, and the first cover body 11, the second cover body 12, and the third cover body 13 are driven by the drive unit 4. Are connected to each other via a link mechanism 15, and each of the cover bodies 11, 12, 13 is set in a first posture, and the cover bodies 11, 12, 13 are juxtaposed in substantially the same plane. The tonneau cover, the first cover body 11 is in the first posture, the third cover body 13 is in the second posture, and they are arranged in the longitudinal direction of the vehicle body so as to form substantially the same plane and the first cover body 11 A second tonneau cover configuration in which the two cover body 12 is set in the third posture on the lower side of the first cover body 11 and the third cover body 13, and the first cover body 11 in the second posture, Cover body 12 and third cover 13 is characterized by being configured so as to select the third tonneau cover forms are both set to the third posture.

  According to a second invention of the present application, in the tonneau cover structure of a convertible top vehicle according to the first invention, a portion near the front end of the first cover body 11 is rotatably supported by the first base 2 on the vehicle body side, The second cover body 12 is rotatably supported by the second base 3 on the vehicle body side via a base plate 16 attached to the second cover body 12 and is driven to rotate by the drive unit 4, and the rear end of the second cover body 12. A first link bar 17 that rotates together with the base plate 16 and the first link bar 17 are connected to the position near the front end of the third cover body 13 so as to be relatively rotatable. A second link bar 18 that connects the end of the link bar 17 and the rear end portion of the first cover body 11, the end of the first link bar 17, and the rear end of the third cover body 13 It is characterized in that Ri is constituted by a third link bar 19 for connecting the sites.

  In the present invention, the following effects can be obtained.

(A) According to the tonneau cover structure of a convertible top vehicle according to the first invention of the present application, in the state where the tonneau cover 1 is set to the first tonneau cover form, the cover bodies 11, 12, 13 are both first. Since these cover bodies 11, 12 and 13 are set in the posture and are arranged in the same plane, the tonneau cover area is the widest, and the trunk lid front end of the trunk room in which the roof is folded and stored in the open state of the roof And reliably cover the opening between the seat at the rear of the passenger compartment and ensure aesthetics,
In a state in which the tonneau cover 1 is set to the second tonneau cover configuration, the first cover body 11 is in the first posture and the third cover body 13 is in the second posture so that they form substantially the same plane. Since the second cover body 12 is set in the second posture in the longitudinal direction of the vehicle body, the tonneau cover 1 as a whole has an intermediate width combining the first and third cover bodies 11 and 13. In the closed state of the roof, the opening between the inner portion of the roof 54 and the seat at the rear of the passenger compartment that is extended in an upwardly inclined state from the rear end of the passenger compartment toward the front of the vehicle body in the closed state of the roof The portion can be reliably covered by the first and third cover bodies 11 and 13 to ensure aesthetics,
In a state where the tonneau cover 1 is set to the third tonneau cover configuration, the first cover body 11 is set to the second posture, and the second cover body 12 and the third cover body 13 are both set to the third posture. Therefore, since the area occupied in the plan view of the tonneau cover 1 at the opening of the trunk room 53 is only the first cover body 11 and the third cover body 13 in the state of being flipped forward, the tonneau cover 1 The occupied area is extremely small, and the substantial opening area of the trunk room 53, that is, the opening area that becomes a moving space when the roof 54 is expanded and stored, is increased to smoothly expand and store the roof 54. Can
Since the first cover body 11, the second cover body 12, and the third cover body 13 are connected to each other via the link mechanism 15 driven by the drive unit 4, the cover bodies 11, 12, 13 are connected to each other. The certainty and reliability of the coordinated posture change operation are ensured.

  As these synergistic effects, it is possible to propose a tonneau cover structure that is excellent in securing its original functions to be provided by the tonneau cover and having convenience in use, reliability in operation, and reliability.

  (B) According to the tonneau cover structure for a convertible top vehicle according to the second invention of the present application, in addition to the effect described in (a) above, the following specific effect is obtained. That is, according to the tonneau cover structure of the convertible top vehicle of the present invention, the first cover body 11 is rotatably supported at the front end portion thereof by the first base 2, and the third cover body 13 is the second cover body. Since the second cover body 12 is supported by the base 3 so as to be rotatable, the second link bar 18 and the third link bar 19 simply change the displacement of the base plate 16 to the first cover. Any structure may be used as long as it can be transmitted to the body 11 and the third cover body 13 as the rotational force. For example, the first cover body 11 and the third cover body may be connected to the second link bar 18 and the third link bar 19, respectively. Compared with the case where the support function and the rotational power transmission function are combined, the number of constituent members of the link mechanism 15 including the second link bar 18 and the third link bar 19 can be reduced. It is possible to simplify the structure, and by extension may contribute to the promotion of cost reduction in the tonneau cover structure.

  Hereinafter, the present invention will be specifically described based on preferred embodiments.

  FIG. 1 shows a case where the roof 54 of the convertible top vehicle 51 is opened and stored in the trunk room 53, and FIG. 3 shows a case where the roof 54 is set to the closed state. Yes. A tonneau cover 1 as the gist of the present invention described below is provided at the boundary between the trunk room 53 and the vehicle compartment 52 of the convertible top car 51.

  The tonneau cover 1 covers a range from the rear portion of the vehicle compartment 52 to the front end edge of the trunk lid 58 in the opened state of the roof 54 shown in FIG. 2 (the form of the tonneau cover 1 at this time is in the scope of claims) 3 in the closed state of the roof 54 shown in FIG. 3, the range from the rear portion of the vehicle compartment 52 to the inside of the rear end portion of the roof 54 is covered (the tonneau cover at this time). 1 is a “second tonneau cover form” in the claims), and it is of course possible to change the form between these two forms. When the roof 54 in the lid state is folded and stored in the trunk room 53, the roof 54 in the storage state in the trunk room 53 is taken out from the trunk room 53 and is closed. In such a case, the roof 54 is temporarily stored in a portion near the front end of the trunk room 53 so that the roof 54 can be stored or taken out (refer to FIG. 7). "Third tonneau cover form").

  The roof 54 includes a front roof portion 55, a rear roof portion 56, and a rear window portion 57 that can be brought into and out of contact with the rear roof portion 56. In the cover state, as shown in FIG. 1, the front roof portion 55 and the rear roof portion 56 are bent and the rear window portion 57 is separated from the rear roof portion 56. In the housed and opened state, as shown in FIG. 3, the front roof portion 55 and the rear roof portion 56 are bent, and the rear window portion 57 is separated from the rear roof portion 56.

  Further, a backboard 61 is disposed at the boundary between the trunk room 53 and the roof 54 so as to partition both of them, and seats 62 and 63 are disposed immediately before the backboard 61.

  Hereinafter, the specific configuration and operation of the tonneau cover 1 will be described in detail.

  First, the overall configuration of the tonneau cover 1 will be described with reference to FIGS. 1 and 2.

  The tonneau cover 1 has a three-part structure composed of a first cover body 11, a second cover body 12, and a third cover body 13 described below, and each of the cover bodies 11, 12, 13 takes a predetermined posture. Thus, the first to third tonneau cover modes described above are realized.

  The said 1st cover body 11 is arrange | positioned in the position nearest to the compartment 52, Comprising: It is comprised with a horizontally long plate-shaped body. The first cover body 11 has a first fixing bar 20 fixed to both ends in the width direction (vehicle width direction) via a pair of front and rear brackets 22, and is closer to the front end of the first fixing bar 20 ( The first fulcrum shaft 31 provided near the vehicle compartment 52) is rotatably supported by the first base 2 provided on the side of the vehicle body at the boundary between the vehicle compartment 52 and the trunk room 53, thereby The fulcrum shaft 31 is rotatable in the direction of arrow RL. In addition, a return spring (not shown) is disposed on the first fulcrum shaft 31 portion, and the first cover body 11 always moves around the first fulcrum shaft 31 in the direction of arrow R by the spring force of the return spring. Is biased to rotate. The restriction of the maximum rotation position of the first cover body 11 in the arrow R direction (that is, the position setting of the first cover body 11 to the first posture) is performed by the stopper (not shown) of the first fixed bar 20. This is realized by restricting the rotation in the direction of arrow R.

  On the other hand, one end of a second link bar 18 to be described later is supported via a fulcrum pin 35 so as to be rotatable relative to the rear end portion (closer to the trunk room 53) of the first fixed bar 20. The first cover body 11 has a posture (hereinafter referred to as “first posture”) in which the upper surface thereof is substantially horizontal as shown in FIG. 1 by the urging force of the return spring and the displacement force of the second link bar 18. 7) and a posture in which the upper surface of the first fulcrum shaft 31 is flipped up toward the passenger compartment 52 and its upper surface extends substantially in the vertical direction (hereinafter, this posture is referred to as a “second posture”). Can be selectively adopted.

  The second cover body 12 is composed of a horizontally long plate-like body, and base plates 16 described below are attached to both ends in the width direction. The base plate 16 is configured by a substantially L-shaped plate body, and one extending portion 6 a is abutted and fixed to the lower surface of the second cover body 12. Further, the other extension part 6b extending downward from the front end side of the one extension part 6a has a disc-shaped tip part and a select gear 8 is formed on the outer peripheral surface thereof.

  The base plate 16 rotates around the second fulcrum shaft 32 by rotatably supporting the second fulcrum shaft 32 provided at the center of the select gear 8 on the second base 3 provided at the side of the vehicle body. The select gear 8 is rotationally driven by the pinion gear 7 of the drive unit 4 that meshes with the select gear 8.

  The upper surface of the second cover body 12 supported by the second fulcrum shaft 32 via the base plate 16 by the rotation of the base plate 16 around the second fulcrum shaft 32 is as shown in FIG. A posture (hereinafter, referred to as a “first posture”) that extends substantially horizontally at the same height as the first cover body 11, and downward from the vicinity of the rear end of the first cover body 11 as shown in FIG. And a posture that extends substantially horizontally at a position below the drive unit 4 as shown in FIG. 7 (hereinafter referred to as a “third posture”). ”).

  In addition, the lower surface of the one extending portion 16a of the base plate 16 is a first stopper surface 41 with which a second stopper pin 39 provided on the second fixing bar 21 side to be described later is engaged, and the other extending portion. The inner corner provided on the side edge of the protruding portion 16b is a second stopper surface 42 with which a first stopper pin 38 provided on the first link bar 17 side described later is engaged.

  The drive unit 4 is connected to the striker 7 attached thereto, for example, includes a speed reduction mechanism 5 and a motor 6, and is fixedly disposed on the side of the vehicle body.

  The third cover body 13 is configured by a horizontally long plate-like body whose rear end edge is arcuate so as to follow the inner surface shape of the rear window portion 57 of the roof 54. And this 3rd cover body 13 is attaching the 2nd fixing bar 21 which consists of a substantially T-shaped plate-shaped body via the pair of front and rear brackets 23 at the both ends of the width direction. Of the two extending portions 21 a and 21 b of the second fixed bar 21, the front end of one extending portion 21 a along the third cover body 13 is supported by one extending portion 16 a of the base plate 16 by a fulcrum pin 37. It is connected to the rear end so as to be relatively rotatable.

  In addition, one end of a third link bar 19 which will be described later is connected to the rear end of the one extending portion 21a. Further, a second stopper pin 39 that engages with the first stopper surface 41 on the base plate 16 side is attached to the tip of the other extending portion 21 b of the second fixing bar 21.

  Then, the third cover body 13 is in the first position as shown in FIG. 1 by the posture changing operation of the second cover body 12 and the displacement force of the third link bar 19. A posture (hereinafter referred to as a “first posture”) in which the upper surface of the first cover body 11 is in the first posture as shown in FIG. 7 and a posture in which the upper surface of the vehicle 52 extends in a force horizontal direction (hereinafter referred to as “second posture”) as compared with the first posture, and a second posture as shown in FIG. The posture can be changed between postures extending in the vertical direction at the lower position (hereinafter referred to as “third posture”).

  The relative relationship between the second stopper pin 39 and the first stopper surface 41 is such that the second cover body 12 and the third cover body 13 are both set to the first posture as shown in FIG. When the base plate 16 (that is, the second cover body 12) rotates in the direction of arrow B and the second cover body 12 is set to the second posture, the second stopper pin 39 is moved to the second position. It is set to engage with the stopper surface 42 (see FIG. 6). The turning force is transmitted to the second stopper pin 39 only when the base plate 16 is further rotated in the arrow B direction.

  The link mechanism 15 described below makes it possible to change the posture of the first cover body 11, the second cover body 12, and the third cover body 13.

  The link mechanism 15 includes a first link bar 17, a second link bar 18, and a third link bar 19 described below.

  The first link bar 17 is rotatably supported by the second fulcrum shaft 32 located at the center of the select gear 8 of the base plate 16, and has one extension end at the second end described below. One end of the link bar 18 is connected by a fulcrum pin 33, and one end of the third link bar 19 is connected by a fulcrum pin 34. A first stopper pin 38 that engages with the second stopper surface 42 on the base plate 16 side is provided at the other extending end of the first link bar 17.

  The relative relationship between the first stopper pin 38 and the second stopper surface 42 on the side of the base plate 16 with which the first stopper pin 38 is engaged is such that the second cover body 12 is set to the first posture as shown in FIG. When the base plate 16 is rotated in the direction of the arrow B by the drive unit 4 from the state and the second cover body 12 is set to the second posture extending in the vertical direction, the first stopper pin 38 is moved to the second position. It is set to engage with the stopper surface 42 (see FIG. 6). The turning force is transmitted to the first stopper pin 38 only when the base plate 16 is further rotated in the arrow B direction.

  As described above, the second link bar 18 has one end connected to the first link bar 17 and the other end connected to the rear end of the first fixing bar 20 on the first cover body 11 side. It is connected. In this case, as described above, the first fixing bar 20 is rotated in the direction of the arrow R around the first fulcrum shaft 31 by a return spring (not shown) so as to position the first cover body 11 in the first posture. Further, the first link bar 17 is supported by the second fulcrum shaft 32. Therefore, as long as no operating force acts on the first link bar 17 side, as shown in FIG. 2, the first cover body 11 is set to the first posture, and the posture of the first cover body 11, that is, Corresponding to the posture of the first fixed bar 20, the posture is automatically set to the first link bar 17 and the second link bar 18.

  In the state where the third cover body 13 is set to the first posture, the third link bar 19 has one end extending to the first link bar 17 and the other end extending to one of the second fixed bars 21. The rear ends of the portions 21a are connected to each other.

  Subsequently, the operation of the tonneau cover 1 according to this embodiment is related to the operation of the trunk lid 58 and the roof 54, so that the roof 54 is opened (the state shown in FIG. 1) to the closed state (FIG. 3). The state shown in FIG.

  First, in the opened state of the roof 54 shown in FIG. 1, the roof 54 is housed in the trunk room 53 with the front roof portion 55, the rear roof portion 56, and the rear window portion 57 constituting the roof 54 folded. Yes. The trunk lid 58 is closed so as to cover the upper side of the roof 54 in the housed state (the trunk lid 58 is in a “closed lid state”).

Further, in the roof open state, the tonneau cover 1 is set to the “first tonneau cover configuration”. Thus, in the state where the tonneau cover 1 is set to the “first tonneau cover configuration”, the cover bodies 11, 12, 13 are both set to the first posture, and the cover bodies 11, 12, 13 are Since the tonneau covers 1 have the widest tonneau cover area because they are juxtaposed in substantially the same plane, the trunk room 53 in which the roof 54 is folded and stored is reliably covered by the tonneau cover 1 when the roof is opened. Its aesthetics are ensured.

  When the roof 54 is closed from the opened state of the roof 54, first, as shown in FIG. 4, the trunk lid 58 is opened so as to jump up from the closed lid state to the vehicle body rear side. The lid is open. Thereafter, the attitude of the tonneau cover 1 is changed in order to secure a space for taking out the roof 54 from the trunk room 53 and deploying it.

  That is, the drive unit 4 is operated, and the base plate 16 is rotated around the second fulcrum shaft 32 in the direction of arrow B (see FIG. 2) by the pinion gear 7. Then, as shown in FIG. 5, the second cover body 12 rotates from the first posture to the second posture side integrally with the rotation of the base plate 16 in the arrow B direction. Further, as the second cover body 12 is rotated, the third cover body 13 is moved in a substantially horizontal movement state from the first posture in a manner that is pulled by the second cover body 12. Then, as shown in FIG. 6, when the second cover body 12 reaches the second posture, the third cover body 13 is set to the second posture and is positioned immediately after the first cover body 11. is doing.

  At this time, the second fulcrum shaft 32 provided on the first link bar 17 of the link mechanism 15 is placed on the second stopper surface 42 on the base plate 16 side (see FIG. 2), and the second stopper The pins 39 engage with the first stopper surface 41 (see FIG. 2) on the base plate 16 side. The form of the tonneau cover 1 at this time is the “second tonneau cover form”, but when the roof 54 is closed, the “second tonneau cover form” is merely a transitional form. Further, the posture is changed to realize the “third tonneau cover form”.

  That is, the base plate 16 is further rotated in the arrow B direction. The rotation of the base plate 16 changes the posture of the second cover body 12 from the second posture to the third posture side. At this time, the first cover body 12 is linked with the operation of the side second cover body 12. The postures of the cover body 11 and the third cover body 13 are changed.

  Specifically, as shown in FIG. 7, in the first cover body 11, the first stopper pin 38 on the first link bar 17 side is engaged with the second stopper surface 42 on the base plate 16 side. Therefore, as the base plate 16 rotates, the first link bar 17 rotates in the direction of arrow B, and the second link bar 18 pushes up the rear end portion of the first fixed bar 20. Rotating in the direction of arrow L around the first fulcrum shaft 31 against the urging force of the return spring, the posture is changed from the first posture to the second posture side.

  On the other hand, since the second stopper pin 39 on the second fixing bar 21 side is engaged with the first stopper surface 41 on the base plate 16 side, the third cover body 13 has the second cover body 12 side. The second posture of the side second cover body 12 is changed from the second posture to the third posture side in accordance with the posture change from the second posture to the third posture.

  When the second cover body 12 is set to the third posture, the first cover body 11 is set to the second posture, and the third cover body 13 is set to the third posture. The That is, the tonneau cover 1 is set to the “third tonneau cover form”.

  In the “third tonneau cover configuration”, the first cover body 11 is set in the second posture, and the second cover body 12 and the third cover body 13 are both set in the third posture. The area occupied by the tonneau cover 1 at the opening in the plan view is only the first cover body 11 and the third cover body 13 in the state of being flipped forward, so that the area occupied by the tonneau cover 1 is extremely small. Thus, the substantial opening area of the trunk room 53, that is, the opening area that becomes a moving space when the roof 54 is unfolded and stored can be increased.

  Therefore, next, as shown in FIGS. 8 and 9, the roof 54 is unfolded from its retracted state with the tonneau cover 1 set to the “third tonneau cover configuration”. That is, a roof support mechanism (not shown) is operated to project the front roof portion 55 toward the upper front end side of the vehicle compartment 52, and the rear roof portion 56 is connected to the rear end portion of the front roof portion 55 and the vehicle compartment 52. The rear window 57 is disposed between the rear ends, and the rear window 57 is disposed inside the rear roof 56 (state shown in FIG. 9).

  Next, as shown in FIG. 9, with the tonneau cover 1 set to the “third tonneau cover configuration”, the drive unit 4 causes the base plate 16 to return and rotate in the direction of arrow A (see FIG. 2). As shown in FIG. 10, the first cover body 11 is set to the first position, the second cover body 12 is set to the second position, and the third cover body 13 is set to the second position. The form of the tonneau cover 1 at this time is the “second tonneau cover form”.

  Thereafter, the trunk lid 58 is closed to make the lid closed. This state is the roof closed state shown in FIG. 3, and the vehicle compartment 52 is covered with the roof 54 from above.

  In the roof closed state, the tonneau cover 1 is set to the “second tonneau cover configuration”, the first cover body 11 is in the first posture, and the third cover body 13 is in the second posture. Since the second cover body 12 is set in the second posture and arranged in the longitudinal direction of the vehicle body so as to form substantially the same plane, the tonneau cover 1 as a whole has the first, third cover body 11, The inner portion of the roof 54 and the vehicle compartment that are extended in an upwardly inclined state from the vehicle rear end side toward the front of the vehicle body when the roof is closed. The opening part between the back board 61 and the back board 61 is reliably covered by the first and third cover bodies 11 and 13, and the aesthetics are ensured.

  The operation of the tonneau cover 1 when the roof 54 is operated from the closed state to the open state is performed in a reverse procedure to the above-described “operation of the tonneau cover 1 when the operation is performed from the open state to the closed state”. The description here is omitted by using the description.
