PROBLEM TO BE SOLVED: To provide a door driving mechanism capable of accomplishing a high accuracy door sealing even without controlling the gear rotating angle accurately. SOLUTION: The door driving mechanism is equipped with two gears 2 and 3 capable of meshing with each other, a pin 33 for cam installed on one of the gears 3, a groove 22 for cam formed in the other gear 2, and a non-cogged part 21b formed on either of the gears 2, whereby when the meshing condition of the gears 2 and 3 is disengaged by the non-cogged part 21b, cam driving is started by the groove 22 and the pin 33, and thereafter the idling condition is generated.
