PROBLEM TO BE SOLVED: To smoothly open and close an automatic door without any step by mutually engaging a fixing member having a rack with a rack coupled with driving means, coupling a rack coupling device with the fixing member, and coupling the crack coupling device and the automatic door mutually with a link. SOLUTION: A fixing member 230 having a rack 210 is formed longitudinally on the side surface of support means 300. The fixing member having the rack 210 is engaged with a pinion 220 coupled rotatably with a shaft 218 of driving means 215. The fixing member 230 is adapted such that a spring 240 is fixed thereinside on the outside of which member a protruded part 270 is provided which part 270 is coupled with a link 260 through a pin. More specifically, there are coupled the protruded part 270 and the link 260 one side of which link is coupled with an opening/closing door 280. Hereby, an opening/closing door 280 as an automatic door is smoothly opened and closed without any step. |
