Is configured to be inserted into the recess c9 formed on the upper surface of the leg connecting member Ca located below, the recess c9 is not formed, and the leg connecting member located above is not formed. The lower part of the grommet G attached to the back surface of Ca
It is possible to reduce the overall height of the stacked leg connecting members C as compared with the case where they are directly placed on the upper surface of the leg connecting members Ca located below, and thus the leg connecting members are connected. The accommodation efficiency of the member C is improved. The locking projection c1, the rattling projection c6, the slide member c3, and the like arranged on the upper surface of the leg connecting member Ca located below are formed on the back surface of the leg connecting member Ca located above. It is inserted in the space surrounded by the rib c7 and is configured so as not to interfere with the stacking of the leg connecting members C. Further, since the side surface of the rattling projection c6 and the side surface of the rib c7 closely face each other, the stacked leg connecting members C become loose, and there is no fear of collapse during stacking.

[0043]

Since the present invention has the constitution described above, it has the following effects.

The lateral movement of the leg connecting member or the synthetic resin pallet body and the movement of the leg connecting member and the synthetic resin pallet body toward or away from each other cause the synthetic resin pallet to move. Since the leg connecting member can be attached to the main body and the leg connecting member can be removed from the synthetic resin pallet main body, the work of attaching the leg connecting member to the synthetic resin pallet main body and the synthetic resin pallet main body Workability of the work for removing the leg connecting member from the base is improved.

Since the locking means for preventing the release of the locked state between the fitting hole formed at the bottom of the leg and the locking projection formed at the leg connecting member is provided, the leg and the leg are connected. It is possible to prevent accidental disengagement with the member.

Since the grommet is attached to the back surface of the leg connecting member, and the concave portion into which the lower part of the grommet can be inserted is formed on the upper surface of the leg connecting member located right above the grommet, the stacked legs are formed. The overall height of the part connecting member can be reduced, and therefore, the accommodation efficiency of the leg connecting members is improved.
