PROBLEM TO BE SOLVED: To provide a cabin falling preventive device of a stacker crane for an automated warehouse, capable of preventing falling of a cabin with a simple structure, by reducing the number of part items. SOLUTION: Swing levers 28 are arranged by two in the cabin 17 in response to two chains. The respective swing levers 28 are energized in the direction for rotating the swing levers 28 downward with a lever support pin 32 as the rotational center by energizing force of a tension spring 31. An arm 41 for transmitting the downward rotational movement of the wing levers 28 to a locking pin 39, is extended toward the locking pin 39 on the swing levers 28. The chains are cut, and when the swing levers 28 rotate downward, the locking pin 39 lowers, and a locking state of the stopper pin 36 of the locking pin 39 is released by transmitting the downward rotational movement of the swing levers 28 to the locking pin 39 by the arm 41.
