PROBLEM TO BE SOLVED: To provide a constant-temperature vessel capable of reducing vibration transmitted to a test part as much as possible. SOLUTION: This constant-temperature vessel is constituted in such a way that air in the vessel 3 of a thermal insulation box body 1 is circulated by a circulation fan 4, and a motor 51 for driving the circulation fan is loaded on an upper side of the thermal insulation box body. The driving motor is attached to a motor mounting plate 52, and a through hole 52b for a cushion material is formed in the motor mounting plate. Moreover, the cylindrical cushion material 56 having a recessed part 56a fitted into the through hole for the cushion material on its outer peripheral face is provided. A collar 57 is inserted into the through hole formed on shaft axis of the cushion material, a bolt 61 for a mounting plate is inserted from an upper side of the collar, and its tip is screw-fitted into the thermal insulation box body.
