By the way, in such a board lifting / lowering device, it is considered that a slider such as a slider pin is installed so as to overlap within a projected area on the side of the board member so as not to protrude from the board member as much as possible. It is done.
This is because the thickness of the entire board member including the slider can be reduced by installing the slider in this way, so that the amount that can be substantially moved up and down can be ensured to the maximum.

  However, when the slider is provided in this way, it is necessary to form a slide engagement groove for engaging the slider in the vicinity of the upper floor surface, so that the upper wall (ceiling) of the slide engagement groove is formed extremely thin. Or it is necessary to eliminate the upper wall (ceiling).

  However, if the upper wall of the slide engagement groove is formed thin, the rigidity of the upper wall is lowered, and there is a risk that the upper wall may be easily deformed when a heavy object is loaded on the upper floor surface. is there. Further, if the upper wall is eliminated, the slide engagement groove is exposed on the upper floor surface, which causes a problem that the appearance of the cargo compartment deteriorates.

  Accordingly, the present invention provides a board lifting device for an automobile luggage compartment configured so that the engagement position of the board member can be changed between the vertical position and the sliding engagement groove of the slide engagement groove while ensuring the maximum amount of movement of the board member. It is an object of the present invention to provide a board lifting device for an automobile luggage compartment that can improve the appearance of the upper floor surface at the upper side and can prevent the deformation of the upper floor surface and increase the load weight.

  According to the present invention, there is provided a board lifting device for an automobile luggage compartment, wherein a board member extending in a horizontal direction is provided in a luggage compartment having an opening at a rear portion of the automobile, a slider member provided on both sides of the board member, and the slider member A board lifting / lowering device for an automobile luggage compartment that includes a slide engagement groove that slides and supports when the board member moves up and down between an upper position and a lower position of the luggage compartment, wherein the slide engagement groove includes Providing a separate cover member that covers at least a part of the slide engagement groove from above, and setting the thickness of the cover member to the extent that the slide engagement groove protrudes into the passing path of the slider member; When the slider member passes, a movement allowing means for moving the lid member upward is provided.

According to the above configuration, the separate lid member that covers the slide engagement groove from above is provided, and the thickness of the lid member is set so as to protrude into the passage trajectory of the slider member. Even if the groove is provided in the vicinity of the upper floor surface, the rigidity of the lid member can be increased, and the rigidity of the member positioned above the slide engagement groove can be increased. Further, since the movement permitting means is provided, the movement of the slider member is not hindered even if the lid member protrudes within the passage locus of the slider member.
For this reason, while the slide engagement groove is provided in the vicinity of the upper floor surface, the lid member prevents exposure of the slide engagement groove on the upper floor surface, and prevents the lid member from being deformed, thereby increasing the load weight. Can be achieved.

The slide engagement groove 30 constitutes an elevating mechanism M for the trunk board 5 together with the slider pin 12a described above. The detailed structure of the lifting mechanism M will be described later.

  As can be seen from FIG. 4, when the trunk board 5 is engaged and supported at the upper fixed position (shown by a solid line), the lower surface portion 7 a of the rear side trim 7 is substantially flush with the trunk board 5. It is set.

  On the other hand, when the trunk board 5 is engaged and supported at the lower fixed position (shown by a broken line), the lower surface portion 7a of the rear side trim 7 becomes the opening edge of the upper position of the trunk board 5 and It is configured to function as an access opening to the lower space (TB).

  Next, the slider pin and the slide engagement groove, which are the lifting mechanism of the trunk board, will be described with reference to FIGS. 5 is a rear perspective view showing the engagement state of the trunk board, FIG. 6 is an overall side view showing the engagement relationship between the slider pin and the slide engagement groove, and FIG. 7 is a CC line in FIG. It is arrow sectional drawing.

  First, as shown in FIG. 5, the slider pin 12a provided on the front side of the trunk board 5 is fitted and supported in a slide engagement groove 30 provided on the board support wall 7b of the rear side trim 7. The front side position of the board 5 is defined. The state shown in FIG. 5 is a state in which the trunk board 5 is in the lower fixed position.

  As will be described later, the slider pin 12a has a diameter substantially equal to the thickness of the trunk board 5 and, together with being made of metal, increases the support rigidity of the trunk board 5. For this reason, the loading weight of the trunk board 5 can be increased.

The slide engagement groove 30 is formed as a concave groove that is substantially r-shaped in side view, and has a width and a depth that allow the slider pin 12a to slide smoothly.
The slide engagement groove 30 includes a horizontal groove portion 31 extending in the front-rear direction at the upper portion, an inclined groove portion 32 extending obliquely downward from the front end of the horizontal groove portion 31, and an upper and lower groove portion extending substantially immediately below the front end lower portion of the inclined groove portion 32. 33. In addition, the horizontal groove part 31 is formed in the state which opened all the upper surfaces, without providing a ceiling wall above it.

  Further, a substantially inverted trapezoidal resin lid member 40 that covers the entire horizontal groove 31 from above is provided at the front end of the horizontal groove 31.

  The lid member 40 is set so that its upper surface 40a is substantially flush with the lower surface 7a of the rear side trim 7 and the upper surface of the trunk board 5 (see FIG. 1). Further, the lower surface 40 b is set so as to contact the bottom surface 31 a of the horizontal groove portion 31.

  By setting in this way, the upper surface 40a of the lid member 40 constitutes a part of the cargo compartment floor surface TF1 (see FIG. 1), and the load acting from the upper surface 40a of the lid member 40 is reduced. It can be directly transmitted to the bottom surface 31a of the horizontal groove 31 to be dispersed.

  Further, the lid member 40 is set so that the rear opening 40c is opened upward with the front rotating shaft 40A as the center, and when the slider pin 12a slides and moves in the front-rear direction in the horizontal groove 31. The horizontal groove 31 is opened.

  Specifically, the slide engagement groove 30 and the slider pin 12a support the slider pin 12a at the rear end (upper support portion 34) of the horizontal groove portion 31 of the slide engagement groove 30 as shown by a solid line in FIG. Thus, the upper fixed position of the trunk board 5 is set to be defined, and the slider pin 12a is moved to the lower end (lower support portion 36) of the upper and lower groove portions 33 of the slide engagement groove 30 as shown by the one-dot chain line. ), The lower fixed position of the trunk board 5 is defined.

  Further, an upper allowable space 39 that allows the slider pin 12 a to move upward is provided above the upper and lower groove portions 33. The front wall 39A of the ascending allowable space 39 has a slightly circular arc shape on the front side so as not to obstruct the turning locus L of the slider pin 12a when rotated upward about the front end 50a of the extending portion 50 of the trunk board 5. Is curved.

  The inclined groove portion 32 extends rearward from a position slightly spaced upward from the lower support portion 36. For this reason, even if the inclination angle α is formed relatively gently, the length of the inclined groove portion 32 in the front-rear direction can be reduced. Therefore, the front-rear direction length S of the slide engagement groove 30 can be made shorter than when the engagement grooves are formed at the same inclination angle α (dotted line).

  Further, an arc guide surface 32A is formed at the lower end of the inclined groove portion 32 so that the upper and lower groove portions 33 and the inclined groove portion 32 are smoothly connected.

  At the center in the front-rear direction of the bottom surface 31a of the horizontal groove portion 31, a protruding portion 37 that protrudes upward is formed. The protrusion 37 is provided so that the slider pin 12a can be securely held by the upper support 34 of the horizontal groove 31.

  The lid member 40 is fixed to a substantially trapezoidal lid body 41 in a side view, a rotating shaft bolt 42 that rotatably supports the lid body 41, a cylindrical collar member 43, and a rear side trim as shown in FIG. A fastening nut 44 is used.

  Among these, the rotating shaft bolt 42 passes through the lid body 41, the cylindrical collar member 43, and the rear side trim 7, and is screwed to the fastening nut 44 to rotate the lid body 41 to the rear side trim 7. It is installed to be free.

  Although not shown in detail, a spring member is provided between the rotating shaft bolt 42 and the lid main body 41 to urge the lid main body 41 in a direction in contact with the bottom surface 31 a of the horizontal groove 31. For this reason, the cover member 40 normally maintains a closed state.

  In addition, as shown in FIG. 6, contact inclined surfaces 45 and 46 that are inclined like wedges are formed on the lower front portion and the lower rear portion of the lid member 40, respectively. Since the contact inclined surfaces 45 and 46 are inclined in a wedge shape, when the cylindrical slider pin 12a comes into contact, the input load is converted into a force to move the lid member 40 upward. The lid member 40 can be raised.

  Therefore, the lid member 40 automatically moves up and down by sliding the trunk board 5 in the front-rear direction.

  The contact inclined surfaces 45 and 46 are formed by a substantially linear plane. However, the contact inclined surfaces 45 and 46 are also formed by a curved surface portion that is recessed in a concave shape so as to correspond to the shape of the slider pin 12a, for example. Also good.

  Further, a cover portion 40B is provided at the rear portion of the lid member 40 so as to extend rearward in a thin shape and cover the slider pin 12a from above. The cover portion 40B is in contact with the slider pin 12a when the slider pin 12a is on the upper support portion.

  For this reason, the slider pin 12a can be completely covered by the lid member 40 from above. Moreover, since the load can be transmitted and distributed to the bottom surface 31a of the horizontal groove 31 via the metal slider pin 12a, the load can be increased.

  Next, the lifting operation of the trunk board using this lifting mechanism will be described with reference to FIGS. FIG. 8 is an operation diagram of the first half when the trunk board is lowered from the upper fixed position to the lower fixed position, FIG. 9 is an operation diagram of the latter half when the trunk board is lowered from the upper fixed position to the lower fixed position, and FIG. FIG. 11 is a first half operation diagram when raising the board from the lower home position to the upper home position, and FIG. 11 is a second half operation diagram when raising the trunk board from the lower home position to the upper home position.

  As shown in FIGS. 8 and 9, when lowering the trunk board 5 from the upper fixed position to the lower fixed position, first, as shown in (a), the trunk board 5 is moved upward from the upper fixed position. Rotate to This rotation is generated with the slider pin 12a as the center of rotation.

  Next, as shown in (b), when the trunk board 5 is pushed in from the rear, the slider pin 12a gets over the protrusion 37 and slides forward. By this sliding movement, the slider pin 12a comes into contact with the contact inclined surface 46 of the lid member 40 and pushes the lid member 40 upward.

  As a result, the horizontal groove portion 31 and the inclined groove portion 32 communicate with each other, and a passage through which the slider pin 12a passes is formed.

  Thereafter, as shown in (c), when the trunk board 5 is further pushed forward, the slider pin 12a passes below the lid member 40 and slides to the inclined groove portion 32.

  Furthermore, as shown in (d), when the trunk board 5 is pushed forward, the slider pin 12a guided by the inclined groove 32 falls downward, and the trunk board 5 falls to the lower position. Then, the slider pin 12 a is guided by the arc guide surface 32 </ b> A and falls into the upper and lower grooves 33.

  And as shown in (e), since the front end 50a of the extension part 50 of the trunk board 5 contacts the lower cargo compartment floor (14), the rear end of the trunk board 5 is pushed further downward. Thus, the trunk board 5 moves to the lower fixed position while moving the front end 50a of the extending portion 50 forward.

  Then, as shown in (f), when the slider pin 12a is positioned on the lower support portion 36 of the upper and lower groove portions 33, the trunk board 5 is positioned at the lower fixed position.

  Thus, the trunk board 5 changes its position from the upper fixed position to the lower fixed position.

  As shown in FIGS. 10 and 11, when raising the trunk board 5 from the lower fixed position to the upper fixed position, first, as shown in (a), the trunk board 5 is moved from the lower fixed position to the rear end. Rotate upward. This rotation is generated with the front end 50a of the extended portion 50 as the center of rotation.

  Next, as shown in (b), the trunk board 5 is pulled backward. Thereby, since the slider pin 12a moves to the inclined groove portion 32, the slider pin 12a can be guided upward by the inclined groove portion 32.

  Thereafter, as shown in (c), when the trunk board 5 is pulled rearward, the slider pin 12 a is guided upward along the inclined groove portion 32. At this time, since the inclination angle α of the inclined groove portion 32 is gentle as described above, the pulling force of the trunk board 5 can be reduced. When the trunk board 5 is pulled up, the slider pin 12a comes into contact with the contact inclined surface 45 of the lid member 40, and pushes the lid member 40 upward.

  Furthermore, as shown in (d), when the trunk board 5 is pulled backward, the slider pin 12a passes under the lid member 40 and gets over the protrusion 37. Thus, the slider pin 12a moves to the upper support portion 34 of the horizontal groove portion 31.

  Finally, as shown in (e), the trunk board 5 is positioned at the upper fixed position by lowering the rear end of the trunk board 5 and placing it on the upper placement portion 17b of the trunk end panel 17. become.

  Thus, the trunk board 5 changes its position from the lower fixed position to the upper fixed position.

Next, the effect of this embodiment comprised in this way is demonstrated.
In this embodiment, a separate lid member 40 that covers the horizontal groove portion 31 of the slide engagement groove 30 from above is provided, and the thickness w (see FIG. 6) of the lid member 40 is set to the slider pin 12a of the slide engagement groove 30. The rotary shaft 40A is provided so that the lid member 40 moves upward when the slider pin 12a passes through.

Thereby, even if the slide engagement groove 30 is provided in the vicinity of the upper luggage compartment floor TF1, the rigidity of the lid member 40 can be increased, and the rigidity of the member positioned above the slide engagement groove 30 is increased. be able to. Further, since the rotating shaft 40A is provided, even if the lid member 40 protrudes in the passage locus R of the slider pin 12a, the sliding movement of the slider pin 12a is not hindered.
Therefore, while the slide engagement groove 30 is provided in the vicinity of the upper cargo compartment floor surface TF1, the lid member 40 prevents the upper engagement chamber floor surface TF1 of the slide engagement groove 30 from being exposed, and the lid member. The deformation of 40 can be prevented and the load weight can be increased.

  Therefore, in the board loading / unloading device of the automobile luggage compartment that is configured so that the engagement position of the trunk board 5 can be changed in the vertical position, the maximum amount of movement of the trunk board 5 can be ensured and the upper portion of the slide engagement groove 30 can be secured. It is possible to improve the appearance of the upper cargo room floor surface TF1 at, and to prevent deformation of the upper cargo room floor surface TF1, thereby increasing the load weight.

Thereby, since the lower surface 40 b of the lid member 40 contacts the bottom surface 31 a of the horizontal groove portion 31, the loading load acting on the lid member 40 can be directly transmitted to the bottom surface 31 a of the horizontal groove portion 31 and dispersed.
For this reason, the loading weight of the upper surface 40a of the lid member 40 can be increased without increasing the support rigidity of the lid member 40 itself and the rotating shaft.
Therefore, the load weight of the lid member 40 can be increased without using a complicated structure, and the load capacity of the cargo compartment can be increased.

In this embodiment, the lid member 40 is provided with a cover portion 40B that comes into contact with the slider pin 12a so as to cover the slider pin 12a from above when the trunk board 5 is in the upper fixed position.
Accordingly, since the cover member 40 includes the cover portion 40B that comes into contact with the slider pin 12a from above, the load applied to the cover member 40 is transmitted to the bottom surface 31a of the horizontal groove portion 31 using the slider pin 12a. Can be dispersed. Further, the upper portion of the slider pin 12 a can be covered with the lid member 40.
For this reason, the load applied from the upper surface 40a of the lid member 40 can be reliably distributed to the bottom surface 31a of the horizontal groove 31 using the strong slider pin 12a, and the load weight can be further increased. Further, it is possible to prevent the slider pin 12a from being exposed on the upper cargo floor surface TF1.
Therefore, the loading weight of the lid member 40 can be increased, and deformation of the upper cargo compartment floor surface TF1 can be suppressed. Moreover, since the slider pin 12a is not exposed to the upper cargo room floor TF1, the appearance inside the cargo compartment T can be improved.

Further, in this embodiment, the slider pin 12a is provided on the side surface of the trunk board 5, and is set so as to have a diameter d1 that substantially matches the plate thickness t1 of the trunk board 5 (see FIG. 6).

A permissible space 39 and an inclined groove portion 32 that guides the slider pin 12a rearward and upward behind the ascending permissible space 39 are provided.
Thereby, since the trunk board 5 is provided with the extension part 50 extended forward, the load amount of the trunk board 5 can be increased by the part provided with the extension part 50, and the slide engagement groove 30 is provided. Is provided with the rising allowance space 39, the trunk board 5 provided with the extending portion 50 can be easily moved upward.
Therefore, even the trunk board 5 having an increased loading weight can be easily moved upward, and the operability of the trunk board 5 can be improved while increasing the loading capacity of the luggage compartment T.

  In this embodiment, the slide member provided on the trunk board 5 is configured by the slider pin 12a. However, for example, a roller member may be provided instead of the slider pin 12a and configured by a slide roller.

  Next, a second embodiment will be described with reference to FIGS. 12 is a schematic side view of the board lifting apparatus of the second embodiment, FIG. 13 is an exploded perspective view of the board lifting apparatus, FIG. 14 is an operation diagram when lowering the trunk board from the upper fixed position to the lower fixed position, and FIG. Fig. 5 is an operation diagram when raising the trunk board from the lower fixed position to the upper fixed position.

  As shown in FIG. 12, in the board lifting apparatus of the second embodiment, the slide engagement groove 130 for guiding the slider pin 112a is configured so as to have a substantially isosceles triangular path in a side view. The raising / lowering path of the pin 112a is set so as to be different between when it is raised and when it is lowered, so as to reduce the operating force when raising the trunk board 105 and shorten the working time when it is lowered.

Specifically, the slide engagement groove 130 is formed by an ascending groove 131 and a descending groove 132 formed by a substantially isosceles triangular path, and a horizontal groove 133 extending rearward from the upper end thereof. The ascending groove 131 is composed of an arc ascending groove 131a set at the lower part and an inclined ascending groove 131b set at the upper part.
Of these, the inclined raising groove 131b is formed with an inclination angle β that is gentler than the inclination angle β ′ of the lowering groove portion 132, and reduces the operating force when the trunk board 105 is pulled up.
In the slide engagement groove 130, the rear end of the horizontal groove portion 133 is set as the upper support portion 34, and the lower end of the descending groove portion 132 is set as the lower support portion 36. As a result, when the slider pin 112a is supported by the lower support portion 36, the trunk board 105 can be positioned at the lower fixed position (dashed line), and when the slider pin 112a is supported by the upper support portion 34. The trunk board 105 can be positioned at the lower fixed position (solid line).

Also, a lid member 140 is installed between the horizontal groove 133 and the descending groove 132 of the slide engagement groove 130 as in the first embodiment.
As shown in FIG. 13, the lid member 140 includes a resin trapezoidal thick lid body 141 and a cylindrical cylinder that is fixed to the front end opening hole 141 a of the lid body 141 so as to penetrate in the vehicle width direction. A collar member 142, a rotary shaft bolt 143 that passes through the collar member 142 and is fastened and fixed to the front side position of the horizontal groove 133, and a magnet rubber sheet 144 that is attached to the lower surface of the lid body 141. Yes. An iron plate 145 is attached to the bottom surface of the horizontal groove 133 so as to correspond to the magnet rubber sheet 144.

  By assembling the lid member 140 to the upper part of the slide engagement groove 130, the horizontal groove 133 that is open at the top can be closed from above as well in this embodiment. In addition, since the lower surface of the lid member 140 is in contact with the bottom surface of the horizontal groove portion 133 in the closed state, the support rigidity of the upper surface of the lid member 140 is increased and the loading weight can be increased. Furthermore, when the slider pin 12a is on the upper support portion 34, the support rigidity of the upper surface of the lid member 40 can be increased via the slider pin 112a, and therefore the load weight of the lid member 140 can be further increased.

  On the other hand, when the lid member 140 is opened with the rotary shaft bolt 143 as the center of rotation, the lid member 140 opens all the horizontal grooves 133, so that the slider pin 112a can be easily put in and out.

  The lid member 140 also has a function of holding the slider pin 12a in a state where the slider pin 12a is supported by the upper support portion 34 in order to maintain the closed state by the magnetic force of the magnet rubber sheet 144. The magnet rubber sheet 144 also has an effect of suppressing sound hitting between the lid member 140 and the bottom surface of the horizontal groove portion 133.

  Therefore, the upward movement of the lid member 40 is suppressed until an input load of a predetermined value or more is applied from the slider pin 12a. Therefore, when the trunk board 105 is rotated around the slider pin 12a and opened / closed. It is possible to prevent the lid member 40 from being accidentally opened and the trunk board 105 from falling downward.

Further, between the rising groove 131 and the lowering groove 132 of the slide engagement groove 130, a flat plate-like control valve body 150 extending obliquely upward is installed.
As shown in FIG. 13, the control valve body 150 includes a resin-made rectangular flat plate-shaped wing member 151, a coil spring 152 that applies an urging force for opening and closing the wing member 151, and a lower end opening hole of the wing member. A cylindrical collar member 153 that penetrates and is fixed in the vehicle width direction, a donut plate washer 154, and the coil spring 152, the collar member 153, and the washer 154 pass through the ascending groove portion 131 and the descending groove portion 132. The rotary shaft bolt 155 is fastened and fixed therebetween.

  By assembling the control valve body 150 in the slide engagement groove 130, as shown in FIG. 12, the tip 150a is in contact with the upper wall 131c of the ascending groove part 131. Therefore, the ascending groove part 131 and the descending groove part 132 are arranged. Will be divided on the upper side.

  Therefore, as will be described later, when the trunk board 105 is lowered from the upper fixed position to the lower fixed position, the slider pin 112a is guided by the control valve body 150 and passes through the lowering groove 132. On the other hand, when the trunk board 105 is raised from the lower fixed position to the upper fixed position, the slider pin 112a guided by the rising groove portion 131 presses the control valve element 150 from the front. The slider pin 112a is opened and guided from the rising groove 131 to the horizontal groove 133.

Next, the operation of lowering the trunk board 105 from the upper fixed position to the lower fixed position will be described with reference to FIG.
First, as shown in (a), the rear end of the trunk board 105 in the upper fixed position is rotated upward with the slider pin 112a as the rotation center.

  Then, as shown in (b), when the trunk board 105 is pushed forward, the slider pin 112a pushes up the lid member 140 from the rear and opens it upward. Thereby, the slider pin 112a is removed from the holding state of the lid member 140, and moves forward in the horizontal groove portion 133.

  Thereafter, as shown in (c), when the trunk board 105 is dropped downward on the front side, the slider pin 112a is guided by the descent groove 132 and falls downward. At this time, the trunk board 105 can be smoothly moved to the lower fixed position by dropping the trunk board 105 so that the inclination of the trunk board 105 gradually becomes horizontal.

  Then, by placing the slider pin 112a on the lower support portion 36 and placing the rear end of the trunk board 105 on the lower placement portion 17c of the trunk end panel 17, the trunk board 105 is moved to the lower fixed position. Will be located.

Further, referring to FIG. 15, the operation of raising the trunk board 105 from the lower fixed position to the upper fixed position will be described.
First, as shown in (a), the rear end of the trunk board 105 in the lower fixed position is rotated upward with the front end 50a of the extending portion 50 as the rotation center. At this time, the slider pin 112a ascends along an arc-shaped locus along the ascending allowable space 39 in the arc ascending groove 131a.

  Next, as shown in (b), when the trunk board 105 is pulled rearward, the slider pin 112a is guided by the inclined rising groove 131b and ascends. Since the slider pin 112a presses the control valve body 150 from the front, the control valve body 150 falls to the rear side, and the slider pin 112a slides upward.

  Thereafter, as shown in (c), when the trunk board 105 is further pulled rearward, the slider pin 112a pushes up the lid member 140 from the front and opens it upward. Thereby, since the horizontal groove part 133 is open | released, the slider pin 112a can be moved to the upper side support part 34. FIG.

As described above, in this embodiment, the path of the slider pin 112a during the lifting operation is set to be different.
For this reason, the trunk board 105 can be lifted with a relatively gentle inclination angle β, and the operation can be easily performed. On the other hand, regarding the lowering operation of the trunk board 105, the trunk board 105 can be quickly dropped at a steep inclination angle β ′, so that the operation time can be shortened.
Therefore, the operability of the raising / lowering operation of the trunk board 105 can be further improved.

Further, in this embodiment, the slider pins 112a are provided on the left and right sides of the front portion of the trunk board 105, and are supported by the slide engagement grooves 130 so that the trunk board 105 is rotatable around the slider pins 112a. Further, the lid member 140 is provided with a magnet rubber sheet 144 that suppresses the upward movement of the lid member 140 until the input load becomes a predetermined value or more.
Thereby, when the operator rotates the trunk board 105 to perform the opening / closing operation, even if an input load is accidentally applied to the lid member 140, the lid member 140 can be prevented from moving upward, The sliding movement of the slider pin 112a can be prevented.
Therefore, when the trunk board 105 is opened / closed using the slider pin 112a as the pivot axis, the trunk board 105 can be prevented from accidentally sliding and the trunk board 105 can be operated stably.
