<p>PROBLEM TO BE SOLVED: To provide a gripping mechanism which improves an efficiency of the gripping work of a rack by preventing an engagement releasing pusher from blocking the engagement of a rack with an engagement part when the rack is gripped, and achieves further reduction of the cost with the structure simplified and miniaturized by simplifying and miniaturizing the structure of the pusher mechanism equipped with an actuator.SOLUTION: The pusher mechanism P of a gripping mechanism 100 includes: first and second pushers 131, 132 for moving a rack 20 in a gripping direction to be gripped and depressed to guides 111 to 114; engaging parts 121 to 123 for preventing the rack 20 from lifting; an engagement releasing pusher 133 for releasing the engagement between the engagement parts 121, 122 and the rack 20; and a single actuator 140 for driving each of the pushers 131 to 133. The pusher 133 is moved between a retracted position at the moving time of the pushers 131, 132 to the gripping direction and an engagement releasing position at the moving time of the pushers 131, 132 to the releasing direction.</p> |
