`
`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
`
`direction of the first refrigeration unit and mounted to a lower surface of the first mounting
`
`board.

`

`Application No.: 15/892,146
`
`8. (Previously Presented) The ultra-low temperature freezer according to claim 6, wherein
`
`a second reinforcing portion is formed, on a lower surface side of the second mounting
`
`board, to extend along the drawing-out direction of the second refrigeration unit.
`
`9. (Previously Presented) The ultra-low temperature freezer according to claim 8, wherein
`
`the second reinforcing portion is a plate member that is folded along the drawing-out
`
`direction of the second refrigeration unit, and mounted to a lower surface of the second mounting
`board.
`
`10. (Currently Amended) The ultra—low temperature freezer according to claim 6, wherein:
`
`the machinery compartment includes a first support member that provides support,
`
`from below the pair of first rail member, at the first reinforcing portion when the first
`
`refrigeration unit is drawn out in the drawing-out direction and
`
`a height of the first reinforcing portion is set to a height at which the first reinforcing
`
`portion contacts the first support member when the first refrigeration unit is drawn out.
