Abstract
A low-temperature storage cooled/maintained in an ultra low temperature range, in which door lowering is automatically modified by an opening/closing operation of a thermal insulating door, and a concave/convex portion which is a contact portion with respect to a door switch disposed on the door can be secured. The low-temperature storage includes a thermal insulation box main body having an opening in a front surface thereof; a thermal insulating door openably/closably attached to the thermal insulation box main body by a plurality of hinges to close the opening; and a cooling device which cools a storage chamber formed by the door and the main body, wherein a spacer having a guide surface to forcibly correct door lowering by a closing operation of the thermal insulating door is disposed on a side on which any hinge is not disposed.
