PROBLEM TO BE SOLVED: To provide a lifting/lowering and opening/closing type exhibition case reducing the height of a base unit by appropriately disposing a lifting/lowering mechanism and air-tightly retaining environment in an exhibition space.SOLUTION: An exhibition case 10 includes: a base unit having an exhibition floor 22; and a first seal member that comes into close contact with an opening end 50a of the case body 50, disposed at a contact part of the base unit. A lifting/lowering mechanism 60 includes a movable part for liftingly/loweringly moving the case body 50, and a guide part 62 surrounding the movable part and consisting of a plurality of cylindrical members 69a-69c. The guide part 62 is disposed inside the case body 50, where a maximum cylindrical member 69a and a minimum cylindrical member 69c are fixedly connected to the inside of the case body 50 and the base unit respectively. The maximum cylindrical member 69a has a first presser member 71 at a tip end 69a1. The base unit has a second seal member at an outer peripheral position of a tip end 69c1 of the minimum cylindrical member 69c. The first presser member 71 and the second seal member come into close contact with each other at a descent position P1 of the case body 50. |
