  The second substrate 120 is a plate member that is provided above the first substrate 110 in the Z direction and is disposed between the pair of first support members 130 and 140 that are separated from each other in the Y direction on the first substrate 110. The second substrate 120 has a predetermined thickness in the Z direction, and is formed in a rectangular shape on the XY plane, like the first substrate 110. The length of the second substrate 120 in the X direction is the same as the length of the first substrate 110 in the X direction, and the length of the second substrate 120 in the Y direction is shorter than the length of the first substrate 110 in the Y direction.

  A pair of third support members 153 and 154 are provided between the first substrate 110 and the second substrate 120. The pair of third support members 153 and 154 are arranged to form the pallet carrying claw insertion spaces S2a and S2b between the first substrate 110 and the second substrate 120. The third support members 153 and 154 have a height lower than the height of the first support members 130 and 140 in the Z direction. Therefore, the end portion in the second substrate 120Y direction is fixed (connected) in contact with the side surface of the first support member 130, 140 extending in the Z direction. The pair of third support members 153 and 154 are formed in a long shape in the X direction similarly to the first support members 130 and 140, and the X direction length is the X direction of the first support members 130 and 140. It is the same length as the length.

  The second support members 151 and 152 are provided on the second substrate 120 between the first support members 130 and 140, and are disposed on the inner side in the Y direction than the pair of first support members 130 and 140. The second support members 151 and 152 include upper end surfaces 151a and 152a each having a predetermined width in the Y direction, and are formed in a long shape in the X direction. The lengths of the second support members 151 and 152 in the X direction are the same as the lengths of the first support members 130 and 140 in the X direction. The second support members 151 and 152 and the third support members 153 and 154 are disposed at the same position across the second substrate 120 in the Y direction.

  The upper end surfaces 151 a and 152 a of the second support member are located at the same height in the Z direction as the upper end surfaces 130 a and 140 a of the first support members 130 and 140 with respect to the first substrate 110. That is, the total of the height of the third support member 153 (154), the thickness of the second substrate 120, and the height of the second support member 151 (152) in the Z direction with respect to the first substrate 110 is the first. It becomes the same as the height of the support members 130 and 140 in the Z direction.

  The upper surface 130a, 140a of the first support member 130, 140 and the upper end surface 151a, 152a of the second support member 151, 152 are the mounting surfaces on which the loading platform 301 between the wheels 302 of the car 300 is mounted. Configured as The mounting surface constituted by the upper end surfaces 130 a and 140 a and the upper end surfaces 151 a and 152 a has a height H <b> 1 in the Z direction from the bottom surface of the first substrate 110. In the car transport pallet 100 shown in FIG. 1, the mounting surface of the car 300 is formed by a plurality of upper end surfaces 130 a, 140 a, 151 a, 152 a arranged in the Y direction.

  As shown in FIG. 2, the car 300 has wheels 302 attached to the four corners of a rectangular loading platform 301 that is a bottom plate, and is configured to be able to run on its own. At least three sides above the loading platform 301 are covered with a fence, and a load can be loaded on the loading platform 301. As shown in FIG. 3, the loading platform 301 is configured to have a height H <b> 2 (<H <b> 1) from the ground contact surface 303 of the wheel 302 to the bottom surface of the loading platform 301.

  The height H1 of the mounting surface in the present embodiment is the height H2 from the ground contact surface 303 of the wheel 302 to the bottom surface of the loading platform 301 with which the claw portion 501 of the forklift 500 abuts, that is, the vehicle height of the loading platform 301. It is provided at a position higher than H2. For this reason, as shown in FIG. 3, in the state in which the bottom surface of the loading platform 301 is mounted on the mounting surface, each wheel 302 is not subjected to the loading load of the car 300, and the car transporting pallet 100 ( The first substrate 110) is in a floating state.

  As described above, the pallet for carrying a car 100 is based on the premise that the car 300 is lifted by the forklift 500 without manually placing or unloading the car 300 on the pallet. 300 is placed.

  On the 2nd board | substrate 120, the 1st support member 130 and the 2nd support member 151 are spaced apart in the Y direction, and the space between the 1st support member 130 and the 2nd support member 151 is for car transport. It is comprised as nail | claw part insertion space S1a. Similarly, a space between the first support member 140 and the second support member 152 that are separated in the Y direction is configured as a car carriage carrying claw portion insertion space S1b.

  Each of the car carriage claw insertion spaces S1a and S1b has an opening in the upper direction in the Z direction and is formed in a concave shape in the lower direction in the Z direction with respect to the placement surface.
