PURPOSE: A door cylinder of a bus equipped in a bus for opening/closing the door is provided to minimize dimension of the cylinder and to detect closed state of the cylinder without alternative parts. CONSTITUTION: The door cylinder comprises a cover(50) capable of horizontally rotating by engaging the cover with a mounting pin(57) at one end of the cover; a cylindrical axis(53); an end cover; insertion hole sloped on the end cover; and a micro-switch having a piston of the door cylinder(52) contacted to a longitudinal tip for conducting on/off operation when the door is completely closed. The insertion hole does not break a sealing between a tube of the door cylinder(52) and the end cover. When the door cylinder engages to the mounting pin(57), the cylindrical axis(53) is connected to the door and activates the door to be closed/opened. |
