PROBLEM TO BE SOLVED: To provide a showcase capable of preventing air curtains in air passages from being disturbed even when either of the first and second air passages is selected. SOLUTION: This open showcase 1 comprises a first air passage H1 cooling all commodities in a showcase body 21 and a second air passage H2 cooling those commodities disposed under the showcase body 21. A variable blow duct 812 movable in the longitudinal direction is connected to the front end of a branch duct 8. When cool air is circulated in the first air passage H1, the variable blow duct 812 is moved to the inner of the the showcase body 21. On the other hand, when cool air is circulated in the second air passage H2, the variable blow duct 812 is moved to the outside of the showcase body 21. By this, even in any of the cool air circulations in the first and second air passages H1 and H2, the air curtains formed at the front part 3a of the showcase body 21 are not disturbed.
