PROBLEM TO BE SOLVED: To make a pallet usable for a long period of time even though a face thereof being in contact with the ground surface is liable to be worn out. SOLUTION: A plurality of projected members 4 each projecting in the direction of thickness toward the ground surface from the underside (the face contacting with the ground surface) of a beam 2 of a pallet are detachably attached to the underside of the beam. For a structure wherewith attachment and detachment can be made freely, a dovetail joint structure (comprising a groove 7 and a dovetail 10) is provided at a point between the projected member 4 and a protuberance 6 at the underside of the beam 2 in the longitudinal direction of the projected member 4 and furthermore, the projected members 4 are arranged, extending from one end to the other end of the pallet, and an internal threads 9 are provided respectively at the upper side faces of the protuberances 6 positioned at both ends with hexagon head bolts 5 screwed down thereon. At the time of engagement for attachment, a corner of the bolt head comes into contact with the end face of the projected member 4 and thereby the projected member 4 is prevented from sliding, and at the time of disengagement for detachment, the corner of the bolt head retreats from the projected member 4 side to the beam 2 side, making the projected member 4 available for insertion into and extraction out of the beam 2.
