The second engaging portion (the lying posture engaging portion a on the table side) 66 is a horizontal groove 68 having an opening 67 in the upper side portion 60, and the horizontal groove 63 extends in a substantially horizontal direction. There is a shielding portion 43 at the boundary portion between the upper side portion 60 of the engaging member piece 57 and the opening 67, and the end portion on the first vertical side portion (front side) 62 side of the horizontal groove 63 reaches under the shielding portion 43.

[0050] There is also a horizontal groove formed from near the upper end of the second vertical side portion (rear side) 63 toward the first vertical side portion (front side) 62 side, and the horizontal groove functions as a third engaging portion (a lying posture engaging portion b on the table side) 70. The horizontal groove constituting the third engaging portion (the lying posture engaging portion b on the table side) 70 is short in length and concave. That is, it can also be said that the third engaging portion (the lying posture engaging portion b on the table side) 70 is a recess formed in the second vertical side portion (rear side) 63. In addition, the mounting table side common engaging member 25 employed in the present embodiment has a curved portion 71 between the base end portion of the first engaging portion (the standing posture engaging portion on the table side) 65 and the base end portion of the second engaging portion (the lying posture engaging portion a on the table side) 66 on the upper side portion 60. Further, there is also a curved portion 72 at the corner portion of the upper end of the second vertical side portion (rear side) 63 of the mounting table side common engaging member 25. A through hole 73 is provided in the central portion of the engaging member piece 57. The mounting table side common engaging member 25 is such that a pair of engaging member pieces 57a and 57b face each other with a gap therebetween.

That is, both the first engagement part (lower protrusion) 50 and the second engagement part (upper protrusion) 51 protruding from one side surface of the sliding member 18 are engaged with the guide groove 88 of the lower-side short-side guide piece 85. Also, both the first engagement part (lower protrusion) 50 and the second engagement part (upper protrusion) 51 protruding from the other side surface of the sliding member 18 are engaged with the lower-side guide groove 77 of the long-side guide piece 82. Therefore, the sliding member 18 does not detach from the column member 30. The sliding member 18 has freedom only in the longitudinal direction of the column member 30, and the sliding member 18 linearly moves along the surface of the column member 30.

[0055] Both the first engaging portion (lower protrusion) 50 and the second engaging portion (upper protrusion) 51 protrude from the guide groove 88 of the lower short-side guide piece 85 and the lower-side guide groove 77 of the long-side guide piece 82. That is, both the first engaging portion (lower protrusion) 50 and the second engaging portion (upper protrusion) 51 protruding from one side surface of the sliding member 18 protrude from the guide groove 88 of the lower short-side guide piece 85. Also, both the first engaging portion (lower protrusion) 50 and the second engaging portion (upper protrusion) 51 protruding from the other side surface of the sliding member 18 protrude from the lower-side guide groove 77 of the long-side guide piece 82.

[0056] Focusing on the lower end portion of the sliding member 18, there is a common engaging member 23 on the fence member side at the lower end portion of the sliding member 18. The common engaging member 23 on the fence member side has a first engaging portion (lower protrusion) 50 and a second engaging portion (upper protrusion) 51. Here, the width of the portions of the first engaging portion (lower protrusion) 50 and the second engaging portion (upper protrusion) 51 of the sliding member 18 is wider than the interval between the engaging plate portions 42 of the engaging member pieces 57a, 57b. Therefore, the first engaging portion (lower protrusion) 50 and the second engaging portion (upper protrusion) 51 protrude outside the engaging member pieces 57a, 57b of the common engaging member 25 on the mounting table side. Therefore, the first engaging portion (lower protrusion) 50 provided at the lower part cannot enter between the two engaging member pieces 57a, 57b and contacts the outer contour lines of the engaging member pieces 57a, 57b. Also, a biasing member 26 is provided between the spring engaging portion 53 of the sliding member 18 and the spring engaging portion 47 of the column member 30, and the sliding member 18 is constantly biased toward the common engaging member 25 on the mounting table side.

[0057] The operation portion 21 of the sliding member 18 is in a posture protruding inside the two column members 30, 31 as shown in FIGS. 2 and 3. The position of the operation unit 21 is near the upper side member 32 of the fence body 20. That is, when the fence member 15 is erected to the deployment posture, the position of the upper end of the sliding member 18 is near the upper side member 32. It is desirable that the position of the sliding member 18 is close to the upper side member 32, and it is desirable that the center of the sliding member 18 is at a position above the middle height of the fence member 15 when the fence member 15 is in the deployment posture.

[0058] The opening 55 provided in the connection part 22 of the sliding member 18 is near the colored marking part 38 provided on the upper part side of the column member 30.

[0059] Next, the functions of the vehicle loading platform 1 will be described with reference to FIGS. 6 and 7. The fence member 15 adopted in this embodiment can be folded around the pin 75 at the lower end. That is, in this embodiment, the fence member 15 can be erected to the deployment posture with respect to the mounting table 10. Further, the fence member 15 can be folded and placed in the storage posture lying along the mounting table 10.

[0060] The positional relationship between the lower part of the column member 30 and the mounting table side common engagement member 25 when the fence member 15 is erected to the deployment posture with respect to the mounting table 10 is as shown in FIGS. 4 and 6(a). That is, the first engagement part (lower protrusion) 50 provided at the lower part of the fence member side common engagement member 23 engages with the vertically grooved first engagement part (table side standing posture engagement part) 65 of the mounting table side common engagement member 25. The lower end of the fence member 15 is pivotally supported by the pin 75, and the first engagement part (lower protrusion) 50 at a position away from the pin 75 engages with the vertically grooved first engagement part (table side standing posture engagement part) 65 of the mounting table side common engagement member 25. Since the lower end of the fence body 20 is pivotally supported by the pin 75, it has freedom only in the rotational direction around the pin 75. On the other hand, the first engagement part (table side standing posture engagement part) 65 of the mounting table side common engagement member 25 is a vertically long groove, and the sliding member 18 provided with the first engagement part (table side standing posture engagement part) 65 has freedom only in the direction along the longitudinal direction of the groove that is the first engagement part (table side standing posture engagement part) 65. That is, the sliding member 18 has freedom only in the vertical direction and has no freedom in the rotational direction around the pin 75. Therefore, the first engaging portion (lower protrusion) 50 provided at the lower portion of the common engaging member 23 on the fence member side and the first engaging portion (table-side standing posture engaging portion) 65 in the form of a longitudinal groove of the common engaging member 25 on the mounting table side bring the fence main body 20 into an engaged state during deployment that maintains the deployed posture.

[0061] When the fence member 15 is placed in a stored posture lying along the mounting table 10, the sliding member 18 is moved upward by operating the operation portion 21. In the present embodiment, since it is near the upper side member 32 of the fence main body 20, the sliding member 18 can be moved upward by grasping the upper side member 32 of the fence main body 20 and the operation portion 21 integrally. Here, since the sliding member 18 can move relative to the column member 30 of the fence main body 20 in the longitudinal direction of the column member 30, only the sliding member 18 can be raised by pulling up the operation portion 21.

[0062] As a result, as shown in Fig. 6(b), the first engaging portion (lower protrusion) 50 of the common engaging member 23 on the fence member side moves upward and disengages from the first engaging portion (table-side standing posture engaging portion) 65 in the form of a longitudinal groove of the common engaging member 25 on the mounting table side. Therefore, the lower end portion of the fence member 15 is pivotally supported only by the pin 75 and can be swung in the direction of the arrow in Fig. 6(b). It is desirable to maintain the state in which the operation portion 21 is grasped and the sliding member 18 is raised even during the swinging, but it is also possible to release the hand from the operation portion 21. That is, in the present embodiment, between the upper side 60, which is the base end portion of the first engaging portion (table-side standing posture engaging portion) 65 and the base end portion of the second engaging portion (table-side lying posture engaging portion a) 66, there is a curved portion 71, which is a smooth curved surface. Therefore, the first engaging portion (lower protrusion) 50 of the common engaging member 23 on the fence member side moves following the curved portion 71.

[0063] As the posture change of the fence member 15 progresses in the inclination direction, the first engaging portion (lower protrusion) 50 of the fence member side common engaging member 23 reaches the eaves portion 43 at the end of the curved portion 71 of the mounting table side common engaging member 25. Here, since the fence member side common engaging member 23 is constantly biased toward the mounting table side common engaging member 25 by the biasing member 26, the first engaging portion (lower protrusion) 50 of the fence member side common engaging member 23 falls into the opening 67 of the second engaging portion (mounting table side lying posture engaging portion a) 66 of the mounting table side common engaging member 25.

[0064] Then, as the rocking of the fence member 15 progresses and the fence member 15 becomes parallel to the mounting table 10, the first engaging portion (lower protrusion) 50 of the fence member side common engaging member 23 fits into the lateral groove 68 of the second engaging portion (mounting table side lying posture engaging portion a) 66 of the mounting table side common engaging member 25. As a result, the sliding member 18 moves in the horizontal direction, the first engaging portion (lower protrusion) 50 slides under the eaves portion 43, and engages with the second engaging portion (mounting table side lying posture engaging portion a) 66. That is, since the sliding member 18 is constantly biased toward the mounting table side common engaging member 25 by the biasing member 26, when the first engaging portion (lower protrusion) 50 gets over the eaves portion 43, it moves to the first vertical side portion (front side) 62 by the biasing force of the biasing member 26 and engages with the second engaging portion (mounting table side lying posture engaging portion a) 66.

[0065] At the same time, the second engaging portion (upper protrusion) 51 of the fence member side common engaging member 23 also moves in the horizontal direction and engages with the third engaging portion (mounting table side lying posture engaging portion b) 70 of the mounting table side common engaging member 25. Here, the first engaging portion (lower protrusion) 50 of the fence member side common engaging member 23 engages with the lateral groove portion of the second engaging portion (mounting table side lying posture engaging portion a) 66 of the mounting table side common engaging member 25, and the first engaging portion (lower protrusion) 50 of the fence member side common engaging member 23 has no freedom of movement in the rocking direction. Similarly, the second engaging portion (upper protrusion) 51 of the fence member side common engaging member 23 engages with the lateral groove-shaped third engaging portion (mounting table side lying posture engaging portion b) 70, and the first engaging portion (lower protrusion) 50 of the fence member side common engaging member 23 has no freedom of movement in the rocking direction. Therefore, the first engaging portion (lower protrusion) 50 provided at the lower portion of the common engaging member 23 on the fence member side and the hook-shaped second engaging portion (table-side lying posture engaging portion a) 66 of the common engaging member 25 on the mounting table side bring the fence main body 20 into an engaged state during storage that maintains the stored posture. Similarly, the first engaging portion (lower protrusion) 50 provided at the upper portion of the common engaging member 23 on the fence member side and the horizontally grooved third engaging portion (table-side lying posture engaging portion b) 70 of the common engaging member 25 on the mounting table side also bring the fence main body 20 into an engaged state during storage that maintains the stored posture.

[0066] When changing the fence main body 20 in the stored posture to the deployed posture, hold the operation portion 21 and move the sliding member 18 to the upper side member 32 of the fence main body 20, move the common engaging member 23 on the fence member side in the horizontal direction, and disengage the first engaging portion (lower protrusion) 50 provided at the lower portion of the common engaging member 23 on the fence member side from the second engaging portion (table-side lying posture engaging portion a) 66 and the third engaging portion (table-side lying posture engaging portion b) 70 of the common engaging member 25 on the mounting table side, and swing the fence main body 20 to the standing posture.

[0067] Next, the functions of the opening 55 provided at the connecting portion 22 of the sliding member 18 and the colored marking portion 38 provided on the upper side of the column member 30 will be described. In the present embodiment, the opening 55 and the column member 30 constitute index means for indicating the position of the common engaging member 23 on the fence member side.

[0068] As described above, the opening 55 provided at the connecting portion 22 of the sliding member 18 is in the vicinity of the colored marking portion 38 provided on the upper side of the column member 30. And in the present embodiment, when the sliding member 18 moves to the upper side member 32 side of the fence main body 20, the first engaging portion (lower protrusion) 50 of the common engaging member 23 on the fence member side moves upward and disengages from the longitudinally grooved first engaging portion (table-side standing posture engaging portion) 65 of the common engaging member 25 on the mounting table side, the opening 55 provided at the connecting portion 22 of the sliding member 18 reaches the position of the colored marking portion 38 provided on the upper side of the column member 30, and the marking portion 38 becomes visible from the outside. Similarly, to change the fence body 20 in the stored position to the deployed position, the sliding member 18 is moved to the upper side member 32 of the fence body 20. When the engagement between the first engaging portion (lower protrusion) 50 and the second engaging portion (upper protrusion) 51 provided at the lower portion of the fence member side common engaging member 23 and the second engaging portion (table side lying position engaging portion a) 66 and the third engaging portion (table side lying position engaging portion b) 70 of the mounting table side common engaging member 25 is released, the opening 55 reaches the position of the colored marking portion 38 provided on the upper side of the column member 30, and the marking portion 38 can be seen from the outside.

[0069] Conversely, when the first engaging portion (lower protrusion) 50 provided at the lower portion of the fence member side common engaging member 23 engages with the longitudinally grooved first engaging portion (table side standing position engaging portion) 65 of the mounting table side common engaging member 25 and the fence body 20 is in the engaged state during deployment to maintain the deployed position, the position of the opening 55 of the sliding member 18 does not match the position of the marking portion 38, and the marking portion 38 cannot be seen from the outside. Similarly, when the first engaging portion (lower protrusion) 50 provided at the lower portion of the fence member side common engaging member 23 engages with the hook-shaped second engaging portion (table side lying position engaging portion a) 66 of the mounting table side common engaging member 25 and the fence body 20 is in the engaged state during storage to maintain the stored position, the position of the opening 55 of the sliding member 18 does not match the position of the marking portion 38, and the marking portion 38 cannot be seen from the outside.

[0070] In short, when the posture of the fence member 15 is stable and the fence member 15 cannot be swung, the position of the opening 55 of the sliding member 18 does not match the position of the marking portion 38, and the marking portion 38 cannot be seen from the outside. Conversely, if the fence member 15 is unstable and the fence member 15 moves, the position of the opening 55 of the sliding member 18 matches the position of the marking portion 38, and the marking portion 38 can be seen from the outside. Since the loading platform 1 for a vehicle according to the present embodiment has an index means for indicating the position of the fence member side common engaging member 23, it is possible to visually confirm whether or not the fence member side common engaging member 23 is engaged with the mounting table side common engaging member 25. In the above-described embodiment, the printing portion 38 is visible when the common engagement member 23 on the fence member side is incompletely engaged with the common engagement member 25 on the mounting table side. Conversely, the printing portion 38 may be visible when the engagement between the two is complete. Also, the color when the engagement between the two is incomplete may be different from the color when the engagement is complete, and some indication may appear in any engagement state. The printing portion 38 may be a character display or a symbol mark.

[0071] In the loading platform 1 for a vehicle according to the present embodiment, a buffer member 76 is provided on the back side of the fence main body 20 at the position of the upper side member 32. In the present embodiment, the position where the buffer member 76 is provided is the position that contacts the mounting table 10 in the stored posture. The fence member 15 swings about the base end portion, and can take a deployed posture standing up with respect to the mounting table 10 and a stored posture along the mounting table 10. And as shown in FIG. 7, the buffer member 76 is at a position that contacts the mounting table 10 in the stored posture. Therefore, it is possible to prevent the portion other than the base end of the fence member 15 from directly hitting the surface of the mounting table 10 and rattling due to vibrations during traveling or the like.

[0072] In the embodiment described above, the sliding member 18 and the like are provided only on one of the column members 30, and only one of the column members 30 is in the engaged state during deployment and the engaged state during storage. However, the sliding member 18 and the like may be provided on both of the column members 30 and 31, and both of the column members 30 and 31 may be in the engaged state during deployment and the engaged state during storage. When adopting this configuration, as shown in FIG. 9, it is desirable to connect the sliding member 18 of one column member 30 and the sliding member 18 of the other column member 31 with a connecting member 80 or the like to interlock the two sliding members 18 and the like.

[0073] Also, the shape of the operation portion 21 is not limited to a frame shape, and may be a lever shape like the operation portion 81 shown in FIG. 10.

[0074] In the above-described embodiment, a plate-shaped member is used to connect the operation unit 21 and the common engagement member 23 on the fence member side. That is, in the above-described embodiment, the connecting portion 22 has rigidity. However, the present invention is not limited to this configuration. For example, a linear member such as a wire, which has no rigidity, may be used to connect the operation unit 21 and the common engagement member 23 on the fence member side.

[0075] In the embodiment described above, two engaging portions 50 and 51 are provided on the fence member 15 side, and three engaging portions are provided on the mounting table 10. The number of engaging portions is not limited to this number, and may be more or less.

[0076] In the vehicle loading platform 1 of the embodiment described above, the first engaging portion (lower protrusion) 50 on the fence member 15 side engages with the first engaging portion (mounting table side standing posture engaging portion) 65 on the mounting table 10 side to maintain the deployed posture, and the same first engaging portion (lower protrusion) 50 on the fence member 15 side engages with the second engaging portion (mounting table side lying posture engaging portion a) 66 on the mounting table 10 side to maintain the stored posture. In the above-described embodiment, the first engaging portion (lower protrusion) 50 on the fence member 15 side is the main engaging portion, and it can be said that the second engaging portion (upper protrusion) 51 and the third engaging portion (mounting table side lying posture engaging portion b) 70 that engages with it are auxiliary engaging portions.

[0077] The vehicle loading platform 1 of the embodiment described above shows an example in which one engaging portion (the first engaging portion (lower protrusion)) 50 on the fence member 15 side engages with two engaging portions 65 and 66 (the first engaging portion (mounting table side standing posture engaging portion) and the second engaging portion (mounting table side lying posture engaging portion a) 66) on the mounting table 10 side. That is, in the vehicle loading platform 1, the common engagement member 23 on the fence member side has at least one engaging portion, and the common engagement member 25 on the mounting table side has two or more engaging portions.

[0078] The present invention is not limited to this configuration, and it is sufficient that one of the common engagement members on the mounting table side or the fence member side has one engaging portion, and the other of the common engagement members on the mounting table side or the fence member side has two or more engaging portions.

[0079] Specifically, the common engaging member 23 on the fence member side may have one engaging portion, and the common engaging member 25 on the mounting table side may have two engaging portions. In the vehicle loading platform 1 of the above-described embodiment, the engaging portion on the fence member 15 side engages with the first engaging portion on the mounting table 10 side to maintain the deployed posture, and the same engaging portion on the fence member 15 side engages with the second engaging portion on the mounting table 10 side to maintain the stored posture. However, the engaging portion on the fence member 15 side may engage with the second engaging portion on the mounting table 10 side to maintain the deployed posture, and the same engaging portion on the fence member 15 side may engage with the first engaging portion on the mounting table 10 side to maintain the stored posture.

[0080] The common engaging member on the fence member side may have two engaging portions, and the engaging portion of the common engaging member on the mounting table side may have one engaging portion. In this case, for example, the first engaging portion of the common engaging member on the fence member side engages with the engaging portion on the mounting table 10 side to maintain the deployed posture, and the second engaging portion on the fence member 15 side engages with the same engaging portion on the mounting table 10 side to maintain the stored posture. Alternatively, the second engaging portion on the fence member 15 side may engage with the engaging portion on the mounting table 10 side to maintain the deployed posture, and the first engaging portion on the fence member 15 side may engage with the same engaging portion on the mounting table 10 side to maintain the stored posture.

[0081] (Second Embodiment) 18 and 19 show an embodiment in which the common engaging member 200 on the fence member side has two engaging portions and the engaging portion of the common engaging member 201 on the mounting table side has one engaging portion. In the vehicle loading platform 202 shown in FIGS. 18 and 19, it has a column member 205 and a support member 203. The column member 205 is swingably supported by the support member 203 via a fixing pin 210. There is a common engaging member 200 on the fence member side at the lower part of the column member 205. The common engaging member 200 on the fence member side has a first engaging hole (first engaging portion) 206 provided integrally with the column member 205 and a second engaging hole (second engaging portion) 208 provided on an auxiliary plate 207 projecting laterally from the column member 205.

[0082] The support member 203 has a movable pin (engagement portion) 211 inserted therethrough. The movable pin 211 is slidably inserted into a sliding hole 212 provided in the support member 203. The movable pin (engagement portion) 211 has freedom of movement only in its axial direction. A guide groove 215 is formed in the movable pin 211. The guide groove 215 has a component in an oblique direction. In the present embodiment, the combination of the support member 203 and the movable pin (engagement portion) 211 functions as a common engagement member 201 on the mounting table side.

[0083] A pin 220 is engaged with the guide groove 215 of the movable pin 211. Further, the pin 220 moves in the vertical direction by operating the operation portion 221. In the present embodiment, since the guide groove 215 has a component in an oblique direction, when the operation portion 221 is moved up and down, the movable pin 211 of the common engagement member 201 on the mounting table side moves in the axial direction. In the present embodiment, when the operation portion 221 is moved upward, the movable pin 211 of the common engagement member 201 on the mounting table side moves in the removal direction, and when the operation portion 221 is moved downward, the movable pin 211 of the common engagement member 201 on the mounting table side moves in the insertion direction.

[0084] In the vehicle loading platform 202 of the present embodiment, as shown in FIG. 18(a), when the column member 205 is in an upright posture and the fence member 102 is in a deployed posture, the first engagement hole (first engagement portion) 206 of the fence member side common engagement member 200 coincides with the position of the movable pin (engagement portion) 211. Further, as shown in FIG. 18(b), when the column member 205 is in a storage posture along the mounting table 231, the second engagement hole (second engagement portion) 208 of the fence member side common engagement member 200 coincides with the position of the movable pin (engagement portion) 211 of the common engagement member 201 on the mounting table side.

[0085] In the loading platform 202 for a vehicle according to this embodiment, when the operation unit 221 is moved up and down as described above, the movable pin (engagement part) 211 of the mounting table side common engagement member 201 moves in the axial direction. In this embodiment, when the operation unit 221 is moved upward, the movable pin 211 moves in a direction to come out of the first engagement hole (first engagement part) 206 and the second engagement hole (second engagement part) 208 of the fence member side common engagement member 200. When the operation unit 221 is moved downward, the movable pin 211 (engagement part) moves in a direction to be inserted into the first engagement hole (first engagement part) 206 and the second engagement hole (second engagement part) 208 of the fence member side common engagement member 200.

[0086] In the loading platform 202 for a vehicle according to this embodiment, when the movable pin 211 (engagement part) of the mounting table side common engagement member 201 is inserted into and engaged with the first engagement hole (first engagement part) 206 of the fence member side common engagement member 200, an engaged state during deployment is achieved, and the deployed posture of the fence member 102 is maintained. Also, when the movable pin 211 (engagement part) of the mounting table side common engagement member 201 is inserted into and engaged with the second engagement hole (second engagement part) 208 of the fence member side common engagement member 200, an engaged state during storage is achieved, and the stored posture of the fence member 102 is maintained.

[0087] In the loading platform 202 for a vehicle according to this embodiment, when the operation unit 221 is moved upward in the engaged state during deployment, the movable pin 211 of the mounting table side common engagement member 201 disengages from the first engagement hole (first engagement part) 206 of the fence member side common engagement member 200, and the engaged state during deployment is released. As a result, the fence main body 232 can be swung to the stored posture. When the fence main body 232 is in the stored posture, by moving the operation unit 221 toward the mounting table side common engagement member 201, the movable pin 211 of the mounting table side common engagement member 201 enters the second engagement hole (second engagement part) 208 of the fence member side common engagement member 200, an engaged state during storage is achieved, and the stored posture of the fence member 102 is maintained. When changing the fence body 232 from the storage position to the deployed position, by moving the operation unit 221 in a direction away from the mounting table side common engagement member 201, the movable pin 211 (engagement part) of the mounting table side common engagement member 201 disengages from the second engagement hole (second engagement part) 208 of the fence member side common engagement member 200, and the engagement state during storage is released. As a result, the fence body 232 can be swung to the deployed position.

[0088] (Third Embodiment) As shown in FIGS. 11 and 12, in the cargo bed 100 for a vehicle according to the third embodiment, the fence member 102 is attached only to one side of the mounting table 101. The fence member 102 has a fence body 103, a table side perforated member 105, and a common engagement member 106, as shown in FIGS. 11 and 12. The fence body 103 has an outer shape in the form of a "U", and has two column members 130, 131 and an upper side member 107 connecting the upper ends of the column members 130, 131. Also, the lower ends of the two column members 130, 131 of the fence body 103 are connected by a tubular member 110. The ends of the tubular member 110 project outside the column members 130, 131. And a rotation prevention engaged part 112 is provided at the protruding portion. The rotation prevention engaged part 112 is a protrusion protruding outside the tubular member 110.

[0089] Near the lower ends of the column members 130, 131, a plate member 113 is attached, and a fence member side hole (fence member side movement hole) 117 is provided in the plate member 113. The fence member side hole (fence member side movement hole) 117 is located at a position protruding laterally from the column members 130, 131. The table side perforated member 105 is a plate provided with a hole (mounting table side fixing hole) 125.

[0090] As shown in FIGS. 13 and 14, the common engagement member 106 has a pin 120 fixed to one surface of a plate-like member 118. The plate-like member 118 is rectangular, and a groove-shaped rotation prevention engagement part 121 is formed on one side.

[0091] The mounting table 101 has two ridges 122 and 123 formed on its surface. The ridges 122 and 123 have a certain degree of elasticity. The ridges 122 and 123 extend in a direction perpendicular to the loading and unloading direction Y of the luggage. The ridges 122 and 123 are provided on both end sides in the loading and unloading direction Y of the luggage. The ridges 122 and 123 may be in a dashed line shape.

[0092] As shown in FIGS. 11 and 12, the fence body 103 has a tubular member 110 rotatably supported by support members 115 and 116 provided on the mounting table 101. Also, the base side perforated member 105 is erected near the fence body 103. The common engagement member 106 is connected to the mounting table 101 by a linear member such as a wire or a string. Therefore, the common engagement member 106 has freedom of movement but cannot be removed from the mounting table 101.

[0093] Next, the functions of the vehicle loading platform 100 will be described. The fence member 102 employed in the present embodiment can be folded around the tubular member 110 at the lower end. That is, in the present embodiment, the fence member 102 can be erected on the mounting table 101 to be in a deployed posture. Also, the fence member 102 can be folded and placed in a storage posture along the mounting table 101.

[0094] In the vehicle loading platform 100 of the present embodiment, when the fence member 102 is erected on the mounting table 101 to be in a deployed posture, as shown in FIGS. 11 and 15, the fence member side hole (fence member side moving hole) 117 of the plate member 113 overlaps with the hole (mounting table side fixing hole) 125 of the base side perforated member 105. Therefore, the pin 120 of the common engagement member 106 is inserted into the fence member side hole (fence member side moving hole) 117 of the plate member 113 and the hole (mounting table side fixing hole) 125 of the base side perforated member 105. As a result, the fence body 103 and the mounting table 101 are engaged via the pin 120 of the common engagement member 106, and the fence body 103 is in an engaged state during deployment that maintains the deployed posture.

[0095] When the fence member 102 is swung and placed in the stored position along the mounting table 101, as shown in FIGS. 16 and 17, the pin 120 of the common engagement member 106 is inserted into the hole of the tubular member 110 of the fence main body 103. At this time, the anti-rotation engagement portion 121 of the common engagement member 106 is engaged with the anti-rotation engaged portion 112 of the tubular member 110. By engaging the anti-rotation engagement portion 121 of the common engagement member 106 with the anti-rotation engaged portion 112 of the tubular member 110, the common engagement member 106 becomes in a state where it cannot rotate relative to the fence member 102. Also at this time, as shown in FIG. 16, one side of the plate-like member 118 of the common engagement member 106 is in surface contact with the surface of the mounting table 101 over the entire surface. As a result, the fence main body 103 is engaged with the mounting table 101 via the plate-like member 118 of the common engagement member 106, and the fence main body 103 is in the engaged state during storage that maintains the stored position.

[0096] That is, when the anti-rotation engagement portion 121 of the common engagement member 106 is engaged with the anti-rotation engaged portion 112 of the tubular member 110, the common engagement member 106 becomes non-rotatable relative to the fence member 102, and the plate-like member 118 of the common engagement member 106 is integrated with the column members 130 and 131 of the fence member 102 in the rotational direction. That is, the column members 130 and 131 and the plate-like member 118 rotate around the tubular member 110. Here, most of the plate-like member 118 extends in the opposite direction of the column members 130 and 131 with respect to the tubular member 110, which is the swing center of the column members 130 and 131. Therefore, when the column members 130 and 131 are rotated in the upright direction, the plate-like member 118 is rotated in the direction of pressing against the mounting table 101 conversely. However, since the plate-like member 118 is in contact with the mounting table 101, the plate-like member 118 cannot rotate, and as a result, the fence member 102 cannot be swung to the standing position.

[0097] The cargo handling platform 100 for a vehicle according to the present embodiment can also be in the traveling posture as shown in FIG. 2. That is, the mounting table 101 is set in the vertical posture and is arranged along the back surface of the cargo box 3. In the loading platform 100 for a vehicle according to this embodiment, two ridges 122 and 123 are formed on the surface of the mounting table 101. Therefore, when the loading platform 100 for a vehicle is in the traveling posture, the ridges 122 and 123 face the cargo box 3. Here, since the ridges 122 and 123 have a certain degree of elasticity, when the loading platform 100 for a vehicle vibrates due to vibration during traveling, the elastic ridges 122 and 123 come into contact with the cargo box 3 and do not damage the cargo box 3.

[0098] The buffer member 76 of the first embodiment may be provided on the loading platform 100 for a vehicle according to this embodiment. Further, the ridges 122 and 123 adopted in the loading platform 100 for a vehicle according to this embodiment may be provided on the loading platform 1 for a vehicle according to the first embodiment.
