PURPOSE:To couple two low temperature showcases without deforming a side surface frame by parallelly providing the two low temperature showcases with their facing side surfaces being approached, and inserting bolt through holes in both frames and an arm of the other coupling member from an arm of one coupling member and screwing the bolt into a nut. CONSTITUTION:A pair of right and left metallic coupling members 16, 17 located in a cold air passage 4 and mounted on right and left sides of a heat insulating wall 2 along the inner surface of a back wall 2A of the same comprise a base part 19 with a U-shaped section attached to a nut plate 18 buried in the back wall 2A and an arm 20. There are provided parallelly two low temperature showcases 1, 1 side by side, and a bolt 26 is inserted into holes 15 in both frames 16, 17 and the arm 20 of the coupling member 17 from the arm 20 of the coupling member 16 and screwed into a nut 27. With such construction, the both low temperature showcases 1, 1 are drawn close to each other without tightening force by the bolt 26 and the nut 27 being exerted on both frames 16, 17, and hence both showcases can be coupled without producing a gap between both frames owing to deformation of the side frames.
