PROBLEM TO BE SOLVED: To provide a pallet which is light in weight, high in manufacturing efficiency, and can replace a constituent member.SOLUTION: In the pallet, a plurality of ridges 27 are arranged in parallel in the longitudinal direction of a deck material at a surface of the deck material 21, a longitudinal girder 15 has a deck material mounting wall 29a which mounts the deck material 21 and a deck material pressing part 29b which faces the deck material surface, a plurality of ridges 33 in a direction intersecting the ridges 27 of the deck material are arranged in parallel at a counter surface to the deck material surface in the deck material pressing part 29b, the ridges 27 of the deck material 21 and the ridges 33 of the longitudinal girder 15 are crushed and friction-welded by making the deck material pressing part 29b of the longitudinal girder 15 pressure-contact with the end of the deck material 21, and the deck material 21 and the longitudinal girder 15 are joined by caulking and joining by forming caulking holes 69 at the deck material mounting wall 29a of the longitudinal girder and the deck material 21. |
