PROBLEM TO BE SOLVED: To attain a higher heat insulating property, strength and a higher presentation property by providing sash bars preventing the movement of sealed gas between the glass plates of a double glazing. SOLUTION: Frame members 12 are provided at the side sections of a slide door 1 provided in the front of a storage chamber 7, a double glazing 14 is fitted to the frame members 12, the gas with low heat conductivity is sealed between an outer glass plate and an inner glass plate, and lattice-like sash bars 21 are provided. The sash bars 21 are constituted of multiple vertical bars 21a extending in the vertical direction and multiple horizontal bars 21b extending in the horizontal direction. Since the sash bars 21 preventing the movement of the gas sealed between the glass plates of the double glazing 14 are provided, the convection of the gas in the double glazing 14 rarely occurs, and the heat insulating property of the double glazing 14 can be improved. The double glazing 14 is supported by the sash bars 21, thus the strength of the double glazing 14 is improved. Since the lattice-like sash bars 21 are provided in the double glazing 14, the presentation effect of stored articles can be increased as compared with a planar decoration.
