## Abstract

A pallet having excellent thermal insulation performance and cushioning property with respect to goods-conveyed while ensuring the strength of the outer surface of the pallet. The pallet includes a plate-like pallet body made of foamed resin, the plurality of legs provided on the bottom surface of the pallet body, and the resin sheet integrated from the bottom surface side of the pallet body by vacuum-forming. Further, the top surface of the pallet body includes the loading surface on which goods-conveyed are placed, and the step portion formed in a shape down-step from the outer peripheral edge of the loading surface to the side surface of the pallet body. The resin sheet covers the bottom surface of the pallet body, the legs, the side surface and the step portion of the pallet body, and the loading surface is not covered with the resin sheet.

## Claims

### Claim 1

A pallet comprising:
a pallet body in a thin rectangular shape made of foamed resin;
a plurality of legs provided on a bottom surface of the pallet body; and
a resin sheet integrated by vacuum-forming from the bottom surface side of the pallet, wherein
a top surface of the pallet body has a loading surface on which goods-conveyed is placed, and a step portion formed in a shape down-step from the outer peripheral edge of the loading surface to the side surface of the pallet body, and
the resin sheet covers the bottom surface of the pallet body, the legs, the side surfaces of the pallet body and the step portion, and the loading surface is not covered with the resin sheet.

### Claim 2 (depends on 1)

The pallet according to claim 1, wherein
the resin sheet has a thin sheet thickness at a portion covering the step portion.

### Claim 3 (depends on 1)

The pallet according to claim 1, wherein
the pallet body and the legs are molded as separate bodies, and
the bottom surface of the pallet body has an exhaust hole made in a thickness direction of the pallet body at a place where the leg is arranged.

### Claim 4 (depends on 3)

The pallet according to claim 3, wherein
the bottom surface of the pallet body has a fitting concave into which the leg is fitted, and
the exhaust hole is provided at a peripheral edge of the fitting concave.

### Claim 5 (depends on 3)

The pallet according to claim 3, wherein
the exhaust hole does not penetrate to the top surface of the pallet body, and
a thickness of 5 mm or more is provided from a bottom of the exhaust hole to the top surface of the pallet body.

### Claim 6 (depends on 1)

The pallet according to claim 1, wherein
a ridge line portion between the step portion and the loading surface is chamfered to be a curved surface.

### Claim 7 (depends on 1)

The pallet according to claim 1, wherein
the loading surface is an exposed surface of the foamed resin forming the pallet body and having a thermal insulation performance and a cushioning property.
