Description

[Technical Field]

[0001] The present invention relates to an end board mounting structure. [Background technology]

[0002] A luggage compartment structure for a vehicle described in Patent Document 1 has been known for some time. In the luggage compartment structure described in Patent Document 1, a plate-shaped member is disposed between a tonneau cover that covers the luggage compartment of the vehicle and the tailgate trim to cover the gap between the tonneau cover and the tailgate trim. The rear end of the plate-shaped member is attached to the tailgate trim via a hinge, and the front end is attached to the tailgate trim by being suspended from the tailgate by a string. In a luggage compartment structure configured in this manner, because the plate-shaped member is attached to the tailgate trim, the plate-shaped member also moves up and down in conjunction with the opening and closing of the tailgate. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-36957 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above configuration, the plate-shaped member is attached to the tailgate trim via a hinge so that it is positioned at the same height as the tonneau cover when the tailgate is closed. Therefore, when luggage that is taller than the tonneau cover is placed in the trunk and the tailgate is closed, the plate-shaped member will hit the luggage with great force. This impact places a heavy load on the plate-shaped member and the hinge, which may cause damage. Furthermore, the impact of the plate-shaped member hitting the luggage may also cause damage to the luggage.

[0005] In this way, if the plate-like member, hinge, or string is damaged by the impact when the tailgate is closed, the plate-like member and the tailgate trim may become partially detached. If the tailgate is opened in a state where the plate-like member and the tailgate trim have become partially detached, There is a risk that the plate-shaped member may fall from the partially detached portion and hit the user.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a simple mounting structure for an end board to a tailgate trim that can stably support the end board whether the tailgate is in an open or closed state. [Means for solving the problem]

[0007] In order to solve the above problems, the technology disclosed in this specification relates to an attachment structure of an end board to a tailgate trim, wherein the end board is arranged between a tonneau board arranged in the luggage compartment of a vehicle and the tailgate trim, and the tailgate trim comprises a trim main body portion, an insertion recess having an opening that opens toward the front of the vehicle on the interior surface of the trim main body portion, a first locking portion provided within the insertion recess, and a second locking portion provided at the opening of the insertion recess, and the end board comprises a board main body portion and an insertion portion that extends toward the rear of the vehicle from a rear portion of the board main body portion in the fore-and-aft direction of the vehicle and is inserted into the insertion recess from the front of the vehicle. The end board is attached to the tailgate trim so as to assume a first state in which the insertion portion is engaged with the first engagement portion within the insertion recess, a second state in which the first state is released when a load is applied to the end board from below, and a third state in which the insertion portion is engaged with the second engagement portion when the tailgate is opened in the second state.

[0008] According to the above configuration, when the insertion portion of the end board is in the first position and luggage that is taller than the tonneau cover is placed in the luggage compartment and the back door is closed, the end board hits the luggage, releasing the insertion portion of the end board from the first position and releasing the end board from its fixed position to the back door trim. Therefore, the end board does not hit the luggage with force, so the end board or the luggage in the luggage compartment is not damaged. Furthermore, even if the back door is closed and the insertion portion of the end board is released from the first position, and the back door is opened and the opening of the insertion recess faces downward, the end board is released from its engagement with the first locking portion but remains engaged with the second locking portion, preventing it from falling. Thus, according to the above configuration, the end board can be supported by the back door trim with a simple structure, whether the back door is open or closed.

[0009] the insertion recess has a bottom portion disposed on the opposite side of the opening in the vehicle longitudinal direction, an upper wall extending from the bottom portion toward the opening, and a lower wall facing the upper wall, the first engaging portion being provided on the upper wall, and the second engaging portion being provided on a lower opening edge of the opening, In the first state, the insertion portion may be engaged with the first engagement portion at the bottom side within the insertion recess from the rear side of the vehicle, and in the third state, the insertion portion may be engaged with the second engagement portion at the opening from the rear side of the vehicle.

[0010] According to the above configuration, the end board can be reliably supported by the back door trim in both the first state and the third state.

[0011] The insertion portion has a base end extending from the board main body portion, a tip end inserted into the insertion recess, and a central portion connecting the base end and the tip end, and in the first state, the tip end of the insertion portion is engaged with the first locking portion on the bottom side within the insertion recess, and an abutment portion that is part of the central portion abuts the second locking portion, and in the first state, the end board can rotate around the abutment portion due to a load from below, and as the rotation occurs, the engagement between the tip end and the first locking portion is released, releasing the first state and entering the second state.

[0012] According to the above configuration, when a load is applied to the end board from below, the end board rotates around the abutment portion, disengaging the tip end from the first locking portion. In this way, the locking of the end board to the tailgate trim can be released by the simple action of rotating the end board.

[0013] The tailgate trim may further include a third locking portion provided on the upper opening edge of the opening, and in the third state, the tip of the insertion portion may be clamped between the second locking portion and the third locking portion.

[0014] According to the above configuration, even in the third state in which the first state is released, the tip of the insertion portion is clamped between the second locking portion and the third locking portion, so that the end board will not fall even when the back door is open and can be held stably.

[0015] The tip of the insertion portion may have a cross-sectional shape along the fore-and-aft direction of the vehicle that is U-shaped and opens upward, and in the first state, the engaging end of the U-shape of the tip portion on the rear side of the vehicle is engaged with the first engaging portion from the rear side of the vehicle, and in the third state, the abutment portion is arranged outside the opening of the insertion recess, the engaging end of the tip portion abuts the third engaging portion, and the bottom of the U-shape of the tip portion is engaged with the second engaging portion, so that the tip portion is clamped between the second engaging portion and the third engaging portion.

[0016] According to the above configuration, the end board can be stably held with a simple configuration in both the first state and the third state.

[0017] The bottom of the U-shape of the tip portion may have a hooking protrusion protruding from its outer surface, and in the third state, the hooking protrusion may be engaged with the second engaging portion from the rear side of the vehicle.

[0018] According to the above configuration, even if the opening of the insertion recess faces downward in the third state in which the tailgate is opened after the first state is released, the hooking protrusion is engaged with the second engaging portion, so the insertion portion and the second engaging portion will not be disengaged, and the end board will not fall off the tailgate trim.

[0019] The tailgate trim may further include a support main body portion that protrudes from the interior surface of the trim main body portion toward the front of the vehicle and supports the end board from below, and the end board may further include a locking portion that protrudes from the underside of the board main body portion and is removably locked from above to the support portion of the support main body portion, and when the insertion portion is in the first state, the locking portion is locked to the support portion, and when a load is applied to the end board from below, the insertion portion is released from the first state and the locking portion and the support portion are unlocked.

[0020] According to the above configuration, the insertion portion is held in the insertion recess in the fore-and-aft direction of the vehicle, and the protruding engagement portion and the support portion are engaged in the up-and-down direction, so that the end board can be stably and reliably held by the tailgate trim in the up-and-down direction and the fore-and-aft direction of the vehicle. [Effects of the Invention]

[0021] According to the mounting structure of an end board to a tailgate trim disclosed in this specification, it is possible to provide a simple configuration of the mounting structure of an end board to a tailgate trim that can stably support the end board whether the tailgate is in an open or closed state.

DETAILED DESCRIPTION OF THE INVENTION

[0023] An embodiment of the present invention will be described in detail below with reference to the drawings. It should be noted that the present invention is not limited to the following embodiment, and can be embodied in various forms with various modifications and improvements based on the knowledge of those skilled in the art. In the drawings, the symbols F, R, U, and D indicate the front, rear, upper, and lower directions of the vehicle, respectively. However, these directions are merely defined for convenience and should not be interpreted as limiting.

[0024] As shown in Figure 1, a tonneau board 2 is installed in a luggage compartment 4 of a vehicle and serves the functions of dividing the luggage compartment 4 vertically and hiding luggage placed in the luggage compartment 4 from view from the outside. The luggage compartment 4 is covered from the rear of the vehicle by a back door 1. The back door 1 is configured to be able to open and close the luggage compartment 4 by rotating around its upper end portion as the rotation center.

[0025] As shown in FIGS. 1 and 2, the tonneau board 2 is composed of three plate-shaped board members 6A, 6B, and 6C connected by hinges. By folding the tonneau board 2 via the hinges, the cargo compartment 4 below the tonneau board 2 can be opened. As shown in FIGS. 1 and 2, of the three board members 6A, 6B, and 6C aligned in the fore-and-aft direction of the vehicle, the rear end 6R of the board member 6C located furthest rearward of the vehicle is curved so that its central portion in the width direction of the vehicle protrudes toward the rear of the vehicle. The front end of the end board 20 located behind the board member 6C is shaped to follow the curved shape of the rear end 6R of the opposing board member 6C. This configuration makes it easy to hook a finger onto the protruding portion of the rear end 6R of the board member 6C when folding the tonneau board 2, making it easy to lift the tonneau board 2.

[0026] 1 and 2, an end board 20 is disposed between the tailgate trim 10 of the tailgate 1 and the tonneau cover 2 so as to close the gap therebetween. The end board 20 is a separate member from the tonneau cover 2, and as shown in Fig. 4, a gap is provided between the front end 22F of the end board 20 and the rear end 6R of the board member 6C of the tonneau cover 2. Furthermore, since the end board 20 is attached to the tailgate trim 10 by the first attachment structure 100 and the second attachment structure 200 in this embodiment, it moves together with the tailgate 1 when the tailgate 1 is opened or closed.

[0027] The first mounting structure 100 will be described with reference to FIGS. 1 to 6. As shown in FIGS. 2 and 4, the back door trim 10 includes a trim main body 12 that constitutes the rear wall of the luggage compartment 4, and a support main body 14 that protrudes forward from the interior surface of the trim main body 12 toward the front of the vehicle. In this embodiment, the support main body 14 protrudes forward from the interior surface of the vehicle at both ends of the trim main body 12 in the vehicle width direction and supports an end board 20 from below. An opening 14B that opens upward is provided in a front end 14A of the support main body 14, and a support portion 16 is attached to the opening 14B. As shown in FIG. 6, the support portion 16 has a clamping portion 18 made of a U-shaped elastic member that opens upward, and the clamping portion 18 can clamp an engaging portion 24 of the end board 20 in the vehicle width direction by elastic force.

[0028] As shown in Figures 3, 4, and 6, the locking portions 24 of the end board 20 protrude from the underside (rear surface) of both ends of the board main body 22 in the vehicle width direction. The locking portions 24 are located in the center of the board main body 22 in the vehicle fore-aft direction or further forward. The locking portions 24 are thin plate-like members extending in the vehicle fore-aft direction, and have protrusions 26 at the tips of both plate surfaces. The locking portions 24 are fixed by clamping both plate surfaces in the vehicle width direction between the clamping portions 18. The clamping direction of the locking portions 24 between the clamping portions 18 is perpendicular to the plate surfaces of the locking portions 24. As shown in Figure 4, when the end board 20 is fixed to the back door trim 10, the board main body 22 is arranged to slope downward toward the rear end 22R. The front end 22F of the board main body 22 is approximately flush with the rear end 6R of the tonneau cover 2.

[0029] 6, the locking portion 24 protrudes perpendicular to the plate surface 22S of the board main body 22, and the two opposing plate pieces 18A of the U-shaped clamping portion 18 extend perpendicular to the opposing surface 14S of the support main body 14 that faces the board main body 22. With this configuration, the locking portion 24 is locked to the support portion 16 so that the attachment / detachment direction to / from the support portion 16 is perpendicular to the plate surface 22S of the board main body 22.

[0030] As shown in Figure 6, at the bottom of the clamping portion 18, there is a gap between the opposing U-shaped plate pieces 18A that is large enough to accommodate the tip end 24A of the locking portion 24, including the protrusion 26. The upper parts of both plate pieces 18A of the clamping portion 18 have locking protrusions 18B protruding from the inner surface, and the gap between the opposing plate pieces 18A is narrower than the gap between the opposing plate pieces 18A at the bottom of the clamping portion 18. The distance between the locking protrusions 18B at the top of the clamping portion 18 is smaller than the dimension of the tip end 24A of the locking portion 24 in the vehicle width direction. The plate pieces 18A of the clamping portion 18 are elastically deformable.

[0031] When attaching the end board 20 to the tailgate trim 10, the locking portion 24 is inserted into the clamping portion 18 from the upper opening. The tip 24A of the locking portion 24, which has the convex portion 26, moves downward between the plate pieces 18A while elastically pushing outward the upper portion of the clamping portion 18, which has the locking projection 26B, until the tip 24A fits into the space between the plate pieces 18A at the bottom. This causes the convex portion 26 of the locking portion 24 to be locked with the locking projection 18B of the clamping portion 18, restricting vertical movement of the end board 20 relative to the tailgate trim 10. Furthermore, because the locking portion 24 is clamped by the clamping portion 18 in the vehicle width direction, the end board 20 is fixed to the tailgate trim 10 and restricted from moving in the vehicle width direction. To remove the end board 20 from the tailgate trim 10, the end board 20 can be lifted up and removed by following the steps reverse to those of the above-described attachment procedure.

[0032] As described above, in this embodiment, the end board 20 is removably fixed to the tailgate trim 10 by engaging the engaging portion 24 with the support portion 16 of the tailgate trim 10. As shown in FIG. 5 , if luggage 80 that is taller than the tonneau board 2 is placed in the luggage compartment 4, when the tailgate 1 is closed, the end board 20 also moves downward and hits the luggage 80. When the end board 20 hits the luggage 80, a load is applied to the end board 20 from below.

[0033] In this embodiment, when a load is applied to the end board 20 from below, the locking portions 24 of the end board 20 and the support portions 16 of the tailgate trim 10 are disengaged. Therefore, even if the tailgate 1 is closed and luggage 80 that is taller than the tonneau cover 2 is placed in the luggage compartment 4 and the end board 20 hits the luggage 80, the end board 20 is detached from the tailgate trim 10 and does not receive a strong impact. In this way, the end board 20 is stably supported with a simple configuration, and when a load is applied from below, the locking portions 24 of the end board 20 and the support portions 16 of the tailgate trim 10 can be easily disengaged, so the end board 20 and the luggage 80 in the luggage compartment 4 will not be damaged.

[0034] The action of the locking portion 24 disengaging from the support portion 16 will be described in detail with reference to FIGS. 4 and 5. As shown in FIG. 4, when the locking portion 24 is locked to the support portion 16, the rear end portion 22R of the end board 20 is in contact with the upper surface of the base end portion 14C of the support main body portion 14. The end board 20 is attached so that the board main body portion 14 can rotate about the rear end portion 22R when a load is applied from below. As shown in FIG. 5, when the back door 1 is closed, the end board 20 hits luggage 80 and a load is applied to the end board 20 from below, the front end 22F of the end board 20 lifts up and rotates upward toward the rear of the vehicle about the rear end portion 22R. As the end board 20 rotates upward, the locking portion 24 also moves upward.

[0035] As the locking portion 24 moves upward, the protrusion 26 of the tip 24A moves upward while elastically pushing outward the upper portion of the clamping portion 18 having the protrusion 26, and when it reaches the opening of the clamping portion 18, the locking portion 24 and the support portion 16 are disengaged. In this way, when a load of a certain level or more is applied from below, the end board 20 rotates, and the locking portion 24 and the support portion 16 are easily disengaged. When the load from below becomes greater than the elastic clamping force of the clamping portion 18 on the locking portion 24, the locking portion 24 and the support portion 16 are disengaged. Furthermore, because the clamping portion 18 clamps and holds the locking portion 24 by elastic force, the locking and disengagement between the support portion 16 and the locking portion 24 can be performed with a simple configuration.

[0036] 4, when the end board 20 is fixed to the back door trim 10, the board main body 22 is arranged so as to slope downward toward the rear end 22R, the plate surface 22S of the board main body 22 is parallel to the opposing surface 14S of the support main body 14, and the rear end 22R is in contact with the base end 14C of the support main body 14. Furthermore, as described above, the locking portion 24 is locked to the support portion 16 so that the attachment / detachment direction to / from the support portion 16 is perpendicular to the plate surface 22S of the board main body 22.

[0037] With this configuration, the direction in which the locking portion 24 disengages from the support portion 16 is approximately parallel to the direction in which the end board 20 moves due to the load it receives from below as the tailgate 1 closes (the direction of the arrow in FIG. 5). In addition, the closing direction of the tailgate 1 and the direction in which the end board 20 moves due to the load it receives from below are approximately parallel. Therefore, when the tailgate 1 is closed, the impact load applied to the end board 20 by luggage that is higher than the tonneau board 2 can smoothly release the lock between the locking portion 24 of the end board 20 and the support portion 16 of the tailgate trim 10.

[0038] The locking portion 24 is a plate-like member that extends parallel to a surface along the rotation direction of the main board portion 22, and the clamping portion 18 holds the locking portion 24 by sandwiching it from both plate surfaces. With this configuration, when the main board portion 22 rotates, force is applied evenly to the plate-like member, making it possible to smoothly release the lock between the support portion 16 and the locking portion 24.

[0039] In the first mounting structure 100 for mounting the end board 20 to the back door trim 10, the back door trim 10 includes a trim main body portion 12 that forms the rear wall portion of the luggage compartment 4, and a support main body portion 14 that protrudes forward from the interior surface of the vehicle compartment of the trim main body portion 12 and supports the end board 20 from below, and the end board 20 includes a board main body portion 22 and a locking portion 24 that protrudes from the underside of the board main body portion 22. The first mounting structure 100 is mainly composed of a support portion 16 provided on the support main body portion 14 and the locking portion 24 that is removably locked to the support portion 16 from above.

[0040] Next, the second mounting structure 200 will be described with reference to Figures 1 to 3 and 7 to 11. As shown in Figures 2 and 7, an insertion recess 30 is provided on the interior surface of the vehicle compartment of the trim main body 12 of the back door trim 10, and the insertion recess 30 has an opening 30A that opens toward the front of the vehicle. In this embodiment, the insertion recess 30 is provided at both ends in the vehicle width direction. The insertion recess 30 is composed of a bottom portion 30B arranged on the opposite side of the opening 30A in the vehicle fore-and-aft direction, an upper wall 30U extending from the bottom portion 30B toward the opening 30A, a lower wall 30L facing the upper wall 30U, and two side walls facing each other between the upper wall 30U and the lower wall 30L.

[0041] A locking member 31 is attached within the insertion recess 30, and the locking member 31 is composed of an upper locking portion 31U provided on the upper wall 30U and a second locking portion 34 provided on the lower opening edge of the opening 30A. The upper locking portion 31U is a plate-shaped member extending along the upper wall 30U, and has a first locking portion 32 disposed within the insertion recess 30 and a third locking portion 36 provided on the upper opening edge of the opening 30A of the insertion recess 30. The end of the upper locking portion 31U of the plate-shaped member facing the insertion recess 30 is the first locking portion 32, and the end of the upper locking portion 31U facing the opening 30A is the third locking portion 36. The second locking portion 34 is a plate-shaped member extending along the lower edge of the opening 30A, which extends in the vehicle width direction. The opening dimension in the vertical direction of the insertion recess 30 is the distance between the second locking portion 34 and the third locking portion 36 at the opening 30A. The locking member 31 may be configured as a single member integrally including the upper locking portion 31U and the second locking portion 34, or may be provided as separate components.

[0042] As shown in Figures 3, 7, and 8, the end board 20 has an insertion portion 40 that extends from the rear end 22R (rear portion) of the board body 22 toward the rear of the vehicle. As shown in Figures 7 and 8, the insertion portion 40 is composed of a base end 42 extending from the back surface of the board body 22, a tip end 46 that is inserted into the insertion recess 30, and a central portion 44 that connects the base end 42 and the tip end 46. Specifically, the base end 42 extends downward from the back surface of the board body 22, and the central portion 44 extends from the lower end of the base end 42 toward the rear and upper side, and then extends rearward while bending to form a recess that opens downward. The tip end 46 is provided behind the central portion 44, and the cross section of the tip end 46 along the fore-and-aft direction of the vehicle has a U-shape that opens upward.

[0043] The base end 42 is fixed to the board main body 22 by a fixing member 50. The central portion 44 has an abutment portion 44C that abuts against the second engagement portion 34. The U-shaped tip portion 46 has a hooking protrusion 48 that protrudes from the outer surface of the bottom portion 46B, and in the state shown in FIG. 7, a gap is provided between the hooking protrusion 48 and the lower wall 30L. In addition, in the state shown in FIG. 7, a gap is provided between the rear end 22R of the board main body 22 and the back door trim 10 of the end board 20.

[0044] Thus, in the second mounting structure 200 for mounting the end board 20 to the back door trim 10, the back door trim 10 has an insertion recess 30 provided on the interior surface of the trim main body 12, and a first locking portion 32 and a second locking portion 34 provided in the insertion recess 30, and the end board 20 has an insertion portion 40 extending from the board main body 22. The second mounting structure 200 is mainly composed of the insertion portion 40, and the first locking portion 32 and second locking portion 34 to which the insertion portion 40 is locked.

[0045] Next, the operation and effect of the second mounting structure 200 will be described. As shown in FIGS. 1, 2, and 7, when the end board 20 is properly fixed to the back door trim 10, the insertion portion 40 of the end board 20 is in the first state shown in FIG. 7 relative to the locking member 31. In the first state, the insertion portion 40 is locked to the first locking portion 32, and the tip portion 46 is locked to the first locking portion 32 on the bottom portion 30B side within the insertion recess 30 from the rear side of the vehicle. More specifically, the U-shaped locking end 46E of the tip portion 46 on the rear side of the vehicle is locked to the first locking portion 32, which is the rear end of the upper locking portion 31U, from the rear side of the vehicle. In addition, in the first state, the abutting portion 44C, which is a part of the center portion 44 of the insertion portion 40, abuts against the second locking portion 34.

[0046] In the first state, when the tailgate 1 is closed, the locking end 46E of the insertion portion 40 is locked to the first locking portion 32 from the rear of the vehicle within the insertion recess 30, restricting forward movement of the insertion portion 40. Furthermore, the abutting portion 44C abuts the second locking portion 34 from above in the opening 30A, restricting downward movement of the insertion portion 40, and the insertion portion 40 is supported by the second locking portion 34. With this configuration, the insertion portion 40 is stably held in the first state, restricting movement of the end board 20 in the front-rear and downward directions, and the end board 20 is stably held to the tailgate trim 10.

[0047] In the first state, when the tailgate 1 is opened, as shown in Fig. 9, the opening 30A of the insertion recess 30 faces downward, and the end board 20 hangs from the tailgate trim 10 of the tailgate 1, which has been lifted up. Even in this state, the locking end 46E of the insertion portion 40 is locked from above by the first locking portion 32 within the insertion recess 30, and the abutting portion 44C of the insertion portion 40 is supported by abutting against the second locking portion 34. With this configuration, the insertion portion 40 is stably held in the first state, and the end board 20 will not come off the tailgate trim 10.

[0048] As shown in FIG. 8 , if luggage 80 taller than the tonneau cover 2 is placed in the luggage compartment 4, when the back door 1 is closed, the end board 20 also moves downward and hits the luggage 80. When the end board 20 hits the luggage 80, a load is applied to the end board 20 from below. When a load is applied to the end board 20 from below, the front end 22F is lifted, and the end board 20 rotates around the abutment portion 44C of the insertion portion 40 that abuts against the second holding portion 34. As the end board 20 rotates, the locking end 46E of the tip portion 46 moves downward, and the locking between the locking end 46E and the first locking portion 32 is released, and the locking end 46E moves away from the first locking portion 32. In this way, the first state is released, and the insertion portion 40 is placed in the second state.

[0049] A gap is provided between the bottom 46B (hooking protrusion 48) of the tip portion 46 and the lower wall 30L, and a gap is also provided between the rear end portion 22R of the board main body 22 and the tailgate trim 10, allowing the end board 20 to rotate about the abutment portion 44C. A load applied to the end board 20 from below causes the end board 20 to rotate about the abutment portion 44C, disengaging the locking end 46E of the tip portion 46 from the first locking portion 32. In this way, the locking of the end board 20 to the tailgate trim 10 can be released by the simple action of rotating the end board 20.

[0050] Furthermore, even if luggage 80 that is taller than the tonneau cover 2 is placed in the luggage compartment 4 and the back door 1 is closed, when the end board 20 hits the luggage 80, the insertion portion 40 and the first locking portion 32 are disengaged and the second state is established, so that even if the end board 20 hits the luggage 80 with great force, the impact can be softened. In this way, the end board 20 is stably supported with a simple configuration, and when a load is applied from below, the locking between the insertion portion 40 of the end board 20 and the first locking portion 32 of the back door trim 10 can be easily released, so that a strong impact is not applied to the end board 20 and the end board 20 or the luggage 80 in the luggage compartment 4 is not damaged.

[0051] In the second state shown in Figure 8, when the back door 1 is opened, the back door 1 rotates upward, and the end board 20 is lifted up along with it. Then, as shown in Figure 10, the opening 30A of the insertion recess 30 faces downward. Because the locking end 46E of the insertion portion 40 is no longer locked to the first locking portion 32, the end board 20 moves downward due to its own weight. Therefore, the insertion portion 40 also moves downward, so the abutting portion 44C moves away from the second locking portion 34, and the tip portion 46 moves toward the opening 30A.

[0052] When the back door 1 is fully opened, the insertion portion 40 is in the third state shown in Figure 10. In the third state, the hooking protrusion 48 of the tip portion 46 is engaged with the second locking portion 34 from above (the rear side of the vehicle) in the opening 30A, and the locking end 46E abuts and is engaged with the third locking portion 36. In the third state, the tip portion 46 of the insertion portion 40 is clamped between the second locking portion 34 and the third locking portion 36, and the central portion 44 and the base end portion 42 are positioned outside the opening 30A. In the third state, the end board 20 is hanging from the back door trim 10.

[0053] Thus, even in the third state after the first state is released, the tip 46 of the insertion portion 40 is sandwiched between the second locking portion 34 and the third locking portion 36, so that the end board 20 will not fall even when the back door 1 is open and can be stably held. Furthermore, in the third state, the abutting portion 44C is disposed outside the opening 30A of the insertion recess 30, the locking end 46E of the tip 46 abuts against the third locking portion 36, and the U-shaped bottom 46B of the tip 46 is locked by the second locking portion 34, so that the tip 46 is sandwiched between the second locking portion 34 and the third locking portion 36. With this configuration, the end board 20 will not fall even when the back door 1 is open and can be stably held. Furthermore, in the third state, even if the opening 30A of the insertion recess 30 faces downward, the hooking protrusion 48 is engaged with the second engagement portion 34 from above, so the engagement between the insertion portion 40 and the second insertion engagement portion 34 will not come loose, and the end board 20 will not fall off the tailgate trim 10.

[0054] Within the range of movement of insertion portion 40 from the second state to the third state accompanying the downward movement of end board 20 when back door 1 is opened, the dimension of tip portion 46 of insertion portion 40 (the dimension from locking end 46E to hooking protrusion 48) is set to be larger than the opening dimension in opening 30A between second locking portion 34 and third locking portion 36. With this configuration, even if back door 1 is opened when insertion portion 40 is in the second state, insertion portion 40 will not come off insertion recess 30, and therefore end board 20 will not fall.

[0055] When removing the end board 20 from the back door trim 10, as shown in Figure 11, the insertion portion 40 is moved from the first state to the second state, and then the end board 20 is rotated while being pulled out toward the front of the vehicle, thereby first moving the hooking protrusion 48 out of the insertion recess 30. Then, the end board 20 is rotated downward to also move the locking end 46E out of the insertion recess 30, thereby allowing the tip portion 46 to be removed from the insertion recess 30. The tip portion 46 can be inserted into the insertion recess 30 by performing the reverse action of that used for removal.

[0056] The end board 20 and the back door trim 10 can be configured to include either the first mounting structure 100 or the second mounting structure 200 alone, but may also be configured to include both the first mounting structure 100 and the second mounting structure 200. In a configuration including both the first mounting structure 100 and the second mounting structure 200, as shown in Fig. 2, the first mounting structure 100 is disposed outward in the vehicle width direction than the second mounting structure 200. In addition, the second mounting structure 200 is disposed further rearward of the vehicle than the second mounting structure 100.

[0057] In a configuration including the first mounting structure 100 and the second mounting structure 200, when mounting the end board 20 to the tailgate trim 10, with the tailgate 1 open, the insertion portion 40 is first inserted into the insertion recess 30 in a direction toward the vehicle interior surface of the trim main body 12, resulting in the second state shown in FIG. 8 . Then, the end board 20 is rotated toward the rear of the vehicle around the abutment portion 44C of the insertion portion 40, and the locking portion 24 is inserted into the support portion 16 in a direction along the vehicle interior surface of the trim main body 12. In this way, the first mounting structure 100 allows the end board 20 to be mounted to the tailgate trim 10 in a direction perpendicular to the plate surface, and the second mounting structure 200 allows the end board 20 to be mounted to the tailgate trim 10 in a direction along the plate surface.

[0058] Furthermore, when removing the end board 20 from the back door trim 10, with the back door 1 open, the end board 20 is rotated toward the front of the vehicle around the abutment portion 44C of the insertion portion 40 and moved away from the support main body portion 14, thereby releasing the engagement between the locking portion 24 and the support portion 16, and releasing the engagement between the locking end 46E and the first locking portion 32. After that, the end board 20 is pulled out toward the front of the vehicle and rotated, thereby allowing the insertion portion 40 to be removed from the insertion recess 30. In this way, the end board 20 can be attached to and removed from the back door trim 10 stably and easily.

[0059] Furthermore, in the above configuration, when the insertion portion 40 is in the first state, the locking portion 24 is locked to the support portion 16, and the insertion portion 40 is locked to the first locking portion 32 and the second locking portion 34, so the end board 20 is stably held relative to the back door trim 10 in the up-down direction, the vehicle width direction, and the vehicle front-rear direction. Also, when a load is applied to the end board 20 from below in the first state, the end board 20 rotates upward about the insertion portion 40, so that the locking portion 24 is unlocked from the support portion 16 and the insertion portion 40 is released from the first state to enter the second state. In the second state, the engagement between the locking portion 24 and the support portion 16 is released, but even if the back door 1 is subsequently opened, the insertion portion 40 enters the third state, and the tip portion 46 of the insertion portion 40 is clamped between the second locking portion 34 and the third locking portion 36, so the end board 20 will not fall and can be held stably.
