The bracket does not interfere in the width direction.

  Therefore, according to the first aspect of the present invention, the deck board can be moved between the upper position and the lower position only by gripping the end portion of the deck board that is not connected by the link arm. Compared with the tonneau board, the working length is short and it is only necessary to support a part of the weight of the deck board. In addition, when the deck boat moves to the upper position, its position is regulated by the upper stopper, and conversely, when the deck board moves to the lower position, its position is regulated by the lower stopper. Stable support of the deck board is guaranteed.

  In the invention described in claim 2, since the elastic urging means for applying the urging force in the forward and reverse directions to the link arm by exceeding the dead point is provided, the deck board is moved from the upper position to the lower position. In the case of moving from the lower position to the upper position, the operation can be performed smoothly.In particular, when moving from the lower position to the upper position, the force of the elastic urging means is extremely It can be moved with a light force.

  In the invention according to claim 3, since the shelf is provided at the rear upper end of the storage chamber, the deck board moved to the upper position is stably and surely supported in combination with the restriction of the upper stopper. it can.

  In the invention of claim 4, when the deck board is moved to the upper position, if the axis of the first shaft is in the vehicle rearward position relative to the axis of the second axis, a heavy object is put on the deck board. When placed, if the deck board falls against the urging force of the elastic urging means, and the axis of the first axis is just above the axis of the second axis, the link arm Although it does not rotate, the link arm rotates backwards during vibration or acceleration of the car, and the deck board is lowered as well, but the axis of the first axis is the true axis of the second axis. Since the vehicle can be rotated to the front position of the vehicle that has passed through the top, the link arm does not reversely move backward due to a heavy object, and the deck board does not fall.

  In the invention according to claim 5, the deck board moved to the upper position is firmly supported by the shelf and the upper stopper, and when the deck board is moved to the lower position, the rear edge of the deck board is the rear upper edge. Since it does not interfere with the shelf portion of this, it can move smoothly to the lower position.

  In the invention according to claim 6, since there is a difference in the width of the upper bracket, the link arm, and the lower bracket, each member is inadvertent when the deck board moves to the upper or lower position or in the process of moving. Does not interfere with each other. Accordingly, the deck board can be smoothly moved up and down.

  In the invention according to claim 7, since the lower bracket extends from the vehicle body structure and protrudes beyond the bottom wall of the storage chamber into the storage chamber, the weight of the entire mechanism including the deck board is reliably and firmly supported. It becomes possible.

  In the invention according to claim 8, since the lower bracket extends from the vehicle body structure and protrudes beyond the front wall of the storage chamber into the storage chamber, the weight of the entire mechanism including the deck board is also ensured. It becomes possible to support firmly.

  In the invention described in claim 9, as in the case of claim 1, the deck board is moved to the upper position and the lower position only by gripping the end portion of the deck board that is not connected by the first and second link arms. Because it can be moved between the two, the working length is shorter than in the case of conventional tonneau boards, and it is only necessary to support a part of the weight of the deck board. It becomes.

  In the invention of claim 10, as in the case of claim 2, since the elastic urging means for applying the urging force in the forward and reverse directions to the second link arm by exceeding the dead point is provided, the deck is provided. Work can be done smoothly when moving the board from the upper position to the lower position, or conversely, when moving from the lower position to the upper position, especially when moving the board from the lower position to the upper position. The urging force of the urging means can be moved with an extremely light force.

  In the invention of claim 11, when the deck board is moved to the upper position, the axis of the third axis is more than the axis of the fourth axis, and the axis of the fourth axis is the fifth axis. When a heavy object is placed on the deck board, the deck board falls against the urging force of the elastic urging means, and the third and fourth axes. If the axis of the shaft is just above the axis of the fourth axis and the fifth axis, the first and second link arms will not rotate, but the first and second axes will not be able to rotate. The link arm turns backward and the deck board is lowered in the same way, but the axis of the 4th axis can be rotated to the front position of the vehicle that passes right above the axis of the 5th axis. Since the axis of the third axis can be rotated to the vehicle front position that has passed right above the axis of the fourth axis, 1, the second link arm is without reversal to the rear, there is no that would lower the deck board.

  In the invention according to claim 12, since the distance between the axis of the third axis and the axis of the fourth axis is longer than the distance between the axis of the fourth axis and the axis of the fifth axis, As a result of the front edge being able to be aligned substantially at the upper and lower positions, it can be arranged with a small gap at the upper and lower positions with respect to the vertical front wall of the storage room, and luggage can be placed inside the storage room from the gap. It can effectively prevent the baggage from falling or being caught in the gap.

  In the invention according to claim 13, since there is a difference in the width of the upper bracket, the first link arm, the second link arm, and the lower bracket, when the deck board is moved to the upper / lower position or in the process of moving. The members do not inadvertently interfere with each other. Accordingly, the deck board can be smoothly moved up and down.

  The present invention presupposes a mechanism for moving up and down a deck board disposed on a floor panel of a deck room provided at the rear of an automobile, an upper bracket for fixing the deck board, and a lower bracket fixed to the floor panel side. A link arm pivotally supported by the upper bracket and the lower bracket, a first shaft pivotally supporting the upper bracket and the link arm, a second shaft pivotally supporting the link arm and the lower bracket, and a deck board An upper stopper that regulates the upper position of the deck and a lower stopper that regulates the lower position of the deck board, and by turning the link arm, the deck board is moved to the upper position and the floor panel covering the opening of the storage room of the floor panel. The deck board can be moved up and down easily by moving it between It is.

  Hereinafter, the present invention will be described in detail based on preferred embodiments illustrated in the drawings. First, the deck board vertical movement mechanism according to the first embodiment was developed as a mechanism for moving up and down the deck board arranged on the floor panel of the deck room provided at the rear of the automobile. An object of the present invention is to easily move the deck board between an upper position covering the opening of the storage room and a lower position along the floor panel with respect to the storage room defined between the board and the board.

  Specifically, as shown in FIGS. 1 and 2, the vertical movement mechanism according to the first embodiment is fixed to the upper bracket 1 for fixing both side surfaces of the front edge of the deck board and the floor panel side. A lower bracket 2, a link arm 3 pivotally supported by the upper bracket 1 and the lower bracket 2, a first shaft 4 pivotally supporting the upper bracket 1 and the link arm 3, and the link arm 3 The structure includes a second shaft 5 that pivotally supports the lower bracket 2 and a tension coil spring 6 that is an elastic biasing means that is mounted between the link arm 3 and the lower bracket 2.

  As shown in FIG. 3, the upper bracket 1 for fixing the deck board includes a flat plate-like upper plate 1a and a U-shaped arm plate 1b. An insertion hole 7 through which the single shaft 4 is inserted is formed so that the upper end portion of the link arm 3 can be pivotally supported, and the link arm 3 to be described later is formed into one piece that defines a U-shape. The cutout window 8 for receiving the mounting pin 16 is formed.

  As shown in FIG. 4, the lower bracket 2 fixed on the floor panel of the deck room is composed of a flat plate-shaped lower plate 2a and a leg plate 2b having a rectangular cross section, and the leg plate 2b has a pair of front plates on its front side. A structure in which projecting pieces 9 are provided so as to form an insertion hole 10 through which the second shaft 5 is inserted at the upper end of each projecting piece 9 so that the lower end of the link arm 3 can be pivotally supported. On the other hand, the upper surface of the leg plate 2b is used as an upper stopper 11 that abuts the lower end edge of the link arm 3 to regulate the upper position of the deck boat, and the lower front portion of the leg plate 2b not provided with the protruding piece 9 described above. Is a lower stopper 12 that abuts the first shaft 4 to regulate the lower position of the deck board. In addition, a configuration in which a mounting pin 13 for hooking the end of the tension coil spring 6 is provided on the side surface of the leg plate 2b is also employed.

  As shown in FIG. 5, the link arm 3 pivotally supported by the upper bracket 1 and the lower bracket 2 has a U-shaped cross section in which only the upper end portion is divided into two forks, and the bifurcated upper end portion. An insertion hole 14 through which the first shaft 4 is inserted is formed, and an insertion hole 15 through which the second shaft 5 is inserted is formed at the lower end of the U-shape, and each of the insertion holes 14 and 15 and the above upper bracket By inserting the first shaft 4 and the second shaft 5 through the insertion hole 7 on the 1 side and the insertion hole 10 on the lower bracket 2 side, the brackets 1 and 2 are rotatably supported. In addition, a mounting pin 16 that hooks the end portion of the tension coil spring 6 is provided to project in the middle portion.

  The tension coil spring 6 mounted between the link arm 3 and the lower bracket 2 normally urges the link arm 3 to one of the upper position and the lower position of the deck board with its urging force. When the link arm 3 rotates beyond the dead point of the tension coil spring 6, the urging force is reversed.

Here, the dead point will be briefly described. The link arm 3 is pivotally supported by the lower bracket 2 around the second shaft 5, and the tension coil spring 6 has a lower end at the lower end in the drawing. Since the left end is hooked on the mounting pin 16 which is a movable end provided on the link arm 3, the tension coil spring 6 has an original short length. The mounting pin 16 is constantly urged in a direction to approach the mounting pin 13 in an attempt to shrink it. For this reason, as shown in FIG. 8, the tension coil spring 6 positioned between the mounting pin 13 and the mounting pin 16 is positioned just above the second shaft 5 serving as the rotation center of the link arm 3. Then, the tension coil spring 6 biases the mounting pin 16 toward the second shaft 5, and the mounting pin 16 cannot rotate around the second shaft 5. As described above, a position where the tension coil spring 6 cannot be rotated although the urging force is applied is called a dead point. In an actual product, the weight of the deck board or link arm is applied in the vertical direction (downward in the figure), so the dead point is only the tension coil spring 6 by combining the biasing force of the tension coil spring 6 and the biasing force due to this weight. However, in any case, the link arm 3 is rotated even though the biasing force of the tension coil spring 6 is working. A position that cannot be called is called a dead point.
With this dead point position as a boundary, the link arm 3 is urged in the clockwise direction by the tension coil spring 6 that tries to contract at a position rotated to the right as much as possible. The link arm 3 is now biased in the counterclockwise direction by the tension coil spring 6 to be applied. The elastic urging means for applying the urging force in two forward and reverse directions by exceeding the dead point is configured in this way.

  In the first embodiment, in relation to the upper bracket 1, the link arm 3, and the lower bracket 2, the members 1 and 3 are moved when the deck board is moved to the upper and lower positions or in the process of moving. As shown in FIG. 6, the width of the arm plate 1b of the upper bracket 1 is increased and the width of the link arm 3 is set to an intermediate size so that the two do not inadvertently interfere with each other. The width of the leg plate 2b is reduced, but the present invention is not limited to this, and the width of the link arm 3 is similarly an intermediate size. Conversely, the arm plate 1b of the upper bracket 1 is used. Even if the width of the lower plate 2 is reduced and the width of the leg plate 2b of the lower bracket 2 is increased, the same effect can be obtained. In any case, it is only necessary that the members 1, 3 and 2 do not interfere with each other in the width direction.

  As for the storage room R defined between the floor panel P and the deck board B, the upper and lower two-stage shelves on which the rear edge of the deck board B is individually placed on the rear upper edge and the rear middle. 17a and 17b are provided, and at least on the rear edge side away from the vertical movement mechanism, the deck board B can be supported horizontally regardless of whether it moves to the upper stage position or to the lower stage position. However, regarding the upper shelf portion 17a, when the front end edge of the deck board B enters the storage chamber R and is slanted, the size is such that it does not interfere with the rear end edge of the deck board B (see FIG. 7). ).

  Therefore, when the deck board B is moved up and down with respect to the storage room R using the vertical movement mechanism of the first embodiment, the deck board B moves to the upper position that covers the opening of the storage room R. As shown in FIG. 7, at the front edge side of the deck board B, the link arm 3 stands up and its lower edge is brought into contact with the upper stopper 11 of the leg plate 2b of the lower bracket 2 so that the upper position of the deck board B is reached. The deck board B is placed on the upper shelf 17a of the storage chamber R on the rear edge side of the deck board B, so that the deck board B itself is supported horizontally at the upper position. However, at this time, the link arm 3 is biased in the X direction in the drawing by the biasing force of the tension coil spring 6. Further, in this state, the first shaft 4 is rotated to the vehicle front position that has passed right above the second shaft 5.

  That is, in this case, if the axis of the first shaft 4 is located at the rear of the vehicle with respect to the axis of the second shaft 5, when a heavy object is placed on the deck board B, the urging force of the tension coil spring 6 is applied. If the deck board B is lowered against this, and the axis of the first shaft 4 is just above the axis of the second shaft 5, the link arm 3 does not rotate, but vibration or vehicle During acceleration, the link arm 3 is rotated rearward, and the deck board B is similarly lowered. However, the vehicle in which the axis of the first shaft 4 passes right above the axis of the second shaft 5. Since it can be rotated to the front position, the link arm 3 does not reversely move backward due to a heavy object, and the deck board B does not fall.

  Therefore, when the deck board B is moved from the upper position to the lower position, the rear end edge placed on the upper shelf 17a of the storage room R of the deck board B is inclined as shown in FIG. When the vehicle is lifted upward and then pulled rearward, the link arm 3 rotates in the Y direction in the drawing against the urging force of the tension coil spring 6 along with the upper bracket 1.

  When the link arm 3 rotates beyond the dead point of the tension coil spring 6, the urging force of the tension coil spring 6 is reversed, and the link arm 3 is automatically moved by the urging force of the tension coil spring 6. Since it is continuously rotated, the front end edge side of the deck board B enters the storage chamber R and thereby tilts.

  Then, finally, as shown in FIG. 9, on the front end edge side of the deck board B, the first shaft 4 that pivotally supports the upper bracket 1 and the link arm 3 is provided at the lower stopper 12 provided on the leg plate 2 b of the lower bracket 2. , The lower position of the deck board B is regulated, and the deck board B is placed on the lower shelf 17b of the storage room R on the rear edge side of the deck board B. Even in the lower position, it is supported in a stable state with a horizontal state. In this case, since the upper shelf 17a of the storage chamber R is set to the size described above, in the process in which the rear edge of the deck board B is placed on the lower shelf 17b, the deck The rear edge of the board B does not interfere with the upper shelf 17a.

  Therefore, this allows the deck board B to move stably to the lower position along the floor panel P, so that it becomes easier to move the deck board B from the upper position to the lower position. In this case, as compared with the case of the conventional tonneau board, the work length is short and it is only necessary to support a part of the weight of the deck board B. In any case, the work becomes easy. The upper bracket 1 is also rotated by the rotation of the link arm 3. In this case, the cutout window 8 provided on the arm plate 1b side connects the mounting pin 16 on the link arm 3 side. Because they accept, they do not interfere with each other.

  Conversely, when the deck board B is moved from the lower position to the upper position, the above-described work order is reversed, but the deck board B is placed on the lower shelf 17b of the storage room R of the deck board B. When the rear end edge is pushed upward and the vehicle is pushed forward, the link arm 3 is linked with the upper bracket 1 against the urging force of the tension coil spring 6 in the figure. Will rotate in the direction.

  When the link arm 3 exceeds the dead point of the tension coil spring 6, the urging force of the tension coil spring 6 is reversed, and the link arm 3 is automatically continued by the urging force of the tension coil spring 6. As a result, the link arm 3 stands up on the front end edge side of the deck board B, and the lower end edge thereof is brought into contact with the upper stopper 11 of the leg plate 2b in the lower bracket 2 so that the deck board B is rotated. The upper position of the board B is regulated, and the deck board B is placed on the upper shelf 17a of the storage chamber R on the rear edge side of the deck board B. Therefore, the deck board B covers the opening of the storage chamber R. It can move to the position. In particular, in this case, when the link arm 3 exceeds the dead point of the tension coil spring 6, the reverse biasing force of the tension coil spring 6 automatically guides the link arm 3 in the direction to stand up. There is a great advantage that can be moved.

  In the first embodiment described above, the lower plate 2a of the lower bracket 2 is directly fixed to the floor panel P defining the storage chamber R, but the present invention is limited to this. From the viewpoint of supporting the weight of the entire mechanism including the deck board B with strength, as shown in FIG. 10A, the lower plate 2a of the lower bracket 2 is fixed to the vehicle body structure side. The extending leg plate 2b of the lower bracket 2 protrudes into the storage chamber R through a through hole 18 provided in the bottom wall of the storage chamber R, or, as shown in FIG. The lower plate 2a is fixed to the vehicle body structure side, and the bent leg plate 2b of the lower bracket 2 extending from the vehicle body structure is passed through the through hole 18 provided in the front wall of the storage chamber R into the storage chamber R. It can also be configured to project.

  Next, the vertical movement mechanism of the deck board B according to the second embodiment will be described. The second embodiment basically follows the configuration of the first embodiment as it is, 11 to 12, the upper bracket 1 has its arm plate 1b separated into two forks, and the lower bracket 2 has its leg plates 2b separated into two forks. When the arm 3 is divided into two parts, the upper stopper 11 provided on the lower bracket 2 is constituted by a pin member provided on the bifurcated leg plate 2b to restrict the upper position of the deck board B. The lower end edge of the link arm 3 divided into two parts is individually brought into contact with the upper stopper 11 made of the pin member. Since other configurations and operational effects are the same as those of the first embodiment, the description thereof is omitted here.

  Further, the vertical movement mechanism of the deck board B according to the third embodiment will be described. The third embodiment includes an upper for fixing the back surfaces on both sides of the front edge of the deck board B as shown in FIGS.

A pair of holdings that form a hole 23 so that the lower end of the second link arm 3B can be pivotally supported and hold the second link arm 3B upright on the inner surfaces of both sides. The wall 24 is configured to project oppositely. Moreover, the structure which protrudes the mounting pin 25 which hooks the edge part of the said tension coil spring 6 on the outer surface of both sides is also employ | adopted.

  As shown in FIG. 17, the first link arm 3A pivotally supported by the upper bracket 1 has a bifurcated upper and lower end, and the third shaft 19 is inserted into the bifurcated upper end. A hole 26 is formed, and an insertion hole 27 through which the fourth shaft 20 is inserted is formed at a bifurcated lower end portion. The insertion holes 26 and 27 and the above-described insertion holes 22 on the upper bracket 1 side will be described later. By inserting the third shaft 19 and the fourth shaft 20 through the insertion hole 28 on the second link arm 3B side, the upper bracket 1 and the second link arm 3B are pivotally supported. .

  In the third embodiment, when the deck board B is moved to the upper / lower position in the relationship between the upper bracket 1, the first link arm 3A, the second link arm 3B, and the lower bracket 2, or the movement. In order to prevent the members 1, 3A, 3B, and 2 from inadvertently interfering with each other during the process, the width of the arm plate 1b of the upper bracket 1 is minimized as shown in FIG. The width of the arm 3A is reduced, the width of the second link arm 3B is set to an intermediate size, and the width of the lower bracket 2 is increased, but in any case, each of the members 1, 3A, 3B, and 2 If it does not interfere in the width direction.

  In the third embodiment, the distance L1 between the axis of the third axis 19 and the axis of the fourth axis 20 is the distance L2 between the axis of the fourth axis 20 and the axis of the fifth axis 21. As a result, the front end edge of the deck board B can be made substantially the same at the upper position and the lower position. As a result, the upper position (FIG. 20) is also lower than the vertical front wall of the storage room R. Even at the position (FIG. 22), it can be arranged with a small gap, and it is possible to effectively prevent the luggage from falling into the storage chamber R from the gap or being caught in the gap.

  Further, when the deck board B is moved to the upper position, the axis of the fourth shaft 20 can be rotated to the vehicle front position that passes right above the axis of the fifth shaft 21, and the third axis Since the axis of the shaft 19 is set so as to be rotatable to the vehicle front position that has passed right above the axis of the fourth shaft 20, the axis of the third shaft 19 is assumed to be the first axis. When a heavy object is placed on the deck board B when the axis of the fourth axis 20 is located at the vehicle rear side of the axis of the fourth axis 20 than the axis of the fifth axis 21, the tensile coil The deck board B is lowered against the biasing force of the spring 6, and the axis of the third axis 19 and the fourth axis 20 is just above the axis of the fourth axis 20 and the fifth axis 21. Although the first and second link arms 3A and 3B do not rotate, the first and second link arms 3A and 3 can be used during vibration or acceleration of the automobile. Rotate backward and the deck board B is lowered in the same manner. However, the deck board B is lowered by the heavy object without the first and second link arms 3A and 3B being reversed backward. There is nothing.

  Therefore, when the deck board B is moved up and down with respect to the storage room R using the vertical movement mechanism of the third embodiment, the deck board B moves to the upper position that covers the opening of the storage room R. As shown in FIG. 20, on the front edge side of the deck board B, the second link arm 3B is held in its standing posture by the holding wall 24 of the lower bracket 2, and at the same time, the first link arm 3A is also from the connecting wall. The standing position is held by the stopper 30 and the upper position of the deck board B is regulated. On the rear edge side of the deck board B, as in the first embodiment, the upper shelf 17a (not shown) of the storage chamber R is shown. As a result, the deck board B itself is horizontally supported at the upper position. At this time, the second link arm is urged by the urging force of the tension coil spring 6. B is being urged in the X direction of the figure with a first link arm 3A.

  Therefore, when the deck board B is moved from the upper position to the lower position, it is placed on the upper shelf 17a (not shown) of the storage room R of the deck board B as shown in FIG. When the rear end edge is lifted obliquely upward and pulled rearward of the vehicle, the first and second link arms 3A and 3B are interlocked with this and the tension coil spring 6 is folded with the upper bracket 1 in a dogleg shape. It will rotate in the Y direction in the figure against the urging force.

  When the second link arm 3B rotates beyond the dead point of the tension coil spring 6, the biasing force of the tension coil spring 6 is reversed, and the second link arm 3B is biased by the tension coil spring 6. Therefore, the front end edge side of the deck board B enters into the storage chamber R.

  Then, finally, as shown in FIG. 22, the second link arm 3B is folded inside the lower bracket 2 and the first link arm 3A is inside the second link arm 3B due to the above-described width difference. Since it is folded, the lower position of the deck board B is automatically regulated on the front end edge side of the deck board B while being fixed to the upper bracket 1 as it is. Similar to the first embodiment, it is placed on the lower shelf 17b (not shown) of the storage room R. Further, in this case, the front end edge of the deck board B can be aligned substantially at the lower position as well as at the upper position, so that the appearance is improved.

  Accordingly, even in the third embodiment, the deck board B can stably move to the lower position along the floor panel P, so that the deck board B is moved from the upper position to the lower position. In this case, as compared with the conventional tonneau board, the working length is shorter and it is sufficient to support a part of the weight of the deck board B. Even so, the work becomes easy. In addition, in the third embodiment, when the deck board B is moved to the lower position, the first and second link arms 3A and 3B are completely folded, so that the deck board B is placed on the floor. As a result of being able to support at a position close to the panel P, there is an advantage that the deck board B is moved at a considerable distance in the vertical direction as compared with the first embodiment.

  On the contrary, when the deck board B is moved from the lower position to the upper position, the above-described work order is performed in reverse, while the rear end edge of the deck board B in the lower position is lifted upward. When the vehicle is pushed forward, the first link arm 3A is rotated in the X direction in the figure along with the upper bracket 1 at the same time, and at the same time, the second link arm 3B is attached with the tension coil spring 6. It will rotate in the X direction in the figure against the force.

  When the second link arm 3B rotates beyond the dead point of the tension coil spring 6, the urging force of the tension coil spring 6 is reversed, and the second link arm 3B is accompanied by the first link arm 3A. As a result, the second link arm 3B abuts against the holding wall 24 of the lower bracket 2 on the front end edge side of the deck board B. At the same time, the first link arm 3A comes into contact with the stopper 30 of the second link arm 3B to regulate the upper position of the deck board B. On the rear edge side of the deck board B, the upper link 17a of the storage chamber R Since it is placed, the deck board B can be moved to an upper position covering the opening of the storage chamber R. Particularly in this case as well, as in the first embodiment, when the second link arm 3B exceeds the dead point of the tension coil spring 6, the second and first link arms 3B Since 3A is automatically guided in the direction to stand up, it can be moved with a very light force.

  Finally, the vertical movement mechanism of the deck board B according to the fourth embodiment will be described. In the fourth embodiment, each of the previous embodiments simply moves the deck board B up and down horizontally. In contrast to this, in addition to this, the deck board B can be partitioned vertically by standing upright in the car deck room.

  Therefore, in the fourth embodiment, as shown in FIGS. 23 and 24, the push-out pins that are elastically biased in the protruding direction on the side surfaces of the deck room and the protruding and extending from the side surfaces or along the side surfaces. A structure is provided in which a support body 32 made of a hook that can be folded is provided, and the deck board B standing in a vertical state can be supported as it is by the support action of the support body 32. The support 32 can be provided on the deck board B side.

  Therefore, although not specifically shown in the fourth embodiment, it goes without saying that the deck board B can be moved between the upper position and the lower position as in the above-described embodiments. In addition to this, the support body returned to the projecting state after rotating the upper bracket 1 together with the deck board B in the forward direction of the vehicle while releasing the projecting state of the support body 32 in the deck room. At 32, if the back surface of the deck board B is supported from both sides, this makes it possible to partition the deck room easily.

  The vertical movement mechanism shown in the fourth embodiment is an application of the mechanism of the first embodiment as it is, but the present invention is not limited to this, and the second embodiment or the third embodiment. It is also possible to apply the example mechanism.

  Since the vertical movement mechanism according to the present invention can easily move the deck board between the upper position covering the opening of the storage room and the lower position along the floor panel, this is provided at the rear of the automobile. If it is applied to a mechanism that moves the deck board arranged on the floor panel of the deck room up and down, it will be very convenient.
