PROBLEM TO BE SOLVED: To provide a space environment testing device having a refrigerant piping connection structure which is applicable to an opening/closing door which is moved straight, adaptable to any vacuum vessel having different sizes, and capable of sufficiently ensuring a work space around the opening/closing door. SOLUTION: In the space environment testing device, an opening/closing door 13 is supported in a straight-movable manner by a guide rail 14 provided in the horizontal direction. Fixed refrigerant pipes 23, 24 in which liquefied nitrogen for cooling a door part shroud flows, and door part refrigerant pipes 17, 18 drawn outside the door from the door part shroud are connected to each other via bendable flexible heat insulating pipes 26, 27. The flexible heat insulating pipes are placed movably on an upper surface of a stage 25 supported from a ceiling part or a wall part in the horizontal direction above the opening/closing door.
