PROBLEM TO BE SOLVED: To provide a mechanism for preventing simultaneous opening of both doors in a pass-through type cabinet positively preventing simultaneous opening of both doors by a simple mechanism and preventing intrusion of various germs into a clean region to protect a sanitary state particularly in medical instrument management. SOLUTION: When both door members 2, 2 are closed, respective tip parts 31, 31 of a rod 3 are pushed into locking members 25, 25 disposed at both door members 2, 2, and a door knob 21 is rotatable to make one door member 2 openable. When one door member 2 is open, the tip part 31 of the rod 3 slips out energized by an energizing member 25b disposed at the locking member 25, and a latching hook 24 is latched to a latching groove 25a of the locking member 25 to impede the rotation of the door knob 21 of the other door member 2 to thereby prevent simultaneous opening of both door members.
