SOLUTION: An operating pin 14, a releasing part 15, and a recess 16 are provided to an actuator 1 which fixes plate materials 11, 12 by a fixing member 13. The operating pin 14 is arranged in the vicinity of corners 11A, 12A between the plate materials 11, 12. The releasing part 15 is formed in the corners 11A, 12A. The recess 16 is open at a middle part of one side. When the actuator 1 is moved to an exposed position when the door 100 closes the entrance and exit, the releasing part 15 and the operating pin 14 are inserted into the safety switch 21 to rotate a rotation cam 21 and the contact part 23 is closed.
