`each of the pair of second extending portions has a first folded portion folded downward
`
`and a second folded portion further folded inward toward a center of the second mountingflard,
`
`and
`
`the machinery compartment includes a pair of second rail members configured to guide
`
`the pair of second extending portions in the drawing-out direction.
`
`6. (Currently Amended) The ultra-low temperature freezer according to claim [[1]] i, wherein
`
`a first reinforcing portion is formed, on a lower surface side of the first mounting
`
`board, to extend along the drawing—out direction of the first refrigeration unit.
`
`7. (Previously Presented) The ultra-low temperature freezer according to claim 6, wherein
`
`the first reinforcing portion is a plate member that is folded along the drawing-out
