PROBLEM TO BE SOLVED: To provide an opening/closing cover mounting structure improved to be highly flexibly adapted to the change of location of a branch duct in a hot-and-cold type cold air circulating showcase. SOLUTION: The showcase has opening/closing covers 11 for closing an air intake opened on a back panel dividing between the interior and a cold air circulation passage according to the setting position of the branch duct. A curling shaft 11b is formed on an upper edge side of each opening/closing cover 11, and supports 14 also serving as partition walls of the cold air circulation passage 3 are raised right and left on the rear side of the back panel. Bearing grooves 14a are notched in the supports 14 according to the arrangement pitch for the opening/closing covers 11 arranged in upper and lower stages, and the curling shaft 11b of the opening/closing cover 11 is fitted into the bearing grooves 14a from the front to openably/closably support each cover.
