[Effect of device]

As described above, the present invention provides a limit switch for detecting an object to be detected when the door is fully opened and stopping the drive device, and an object for detecting the object when the door is fully closed and stopping the drive device. Since the limit switch block with the limit switch of
When inspecting or exchanging the limit switch, there is an advantage that the limit switch block can be removed from the column and the limit switch can be easily inspected or exchanged. In addition, a rotation shaft provided at the base end of the arm that supports the door is rotatably supported in the upper end of the support, and a drive device for driving the arm to open and close the door is installed in the support. Since the object to be detected, which is provided and rotates integrally with the rotation axis, is provided in the column, the object to be detected is directly rotated by the rotation axis of the arm that supports the door and acts on the limit switch in the column. Therefore, the limit control can be surely performed without being affected by the outside, and moreover, all the members related to the drive, such as the rotary shaft, the detected body, and the drive device are in the support column. Since it is not housed and does not project to the outside, the appearance and safety can be improved.
