PROBLEM TO BE SOLVED: To simplify a pulling cable groove and smoothly rotate a wire cable, by supporting the front and rear side guide wheels by a vertical shaft, with guide rails at the front and rear sides and horizontally rotating the wheels to open/close a slide door by a wire cable. SOLUTION: A driving wheel is rotated by switching on a motor. And a wire cable 8 is moved for tension. A bracket 7 fixing both ends of the wire cable 8 is slid. And then, a slide door 6 is automatically opened or closed. In this case, a guide pipe for the wire cable is not required and only the wire cable is required. The guide rails 1 are arranged on the front and rear sides. Since the front side guide wheel 11 and the rear side guide wheel 12 are supported by vertical shafts, The wheels are horizontally rotated and hence, the movement is smooth. The intermediate guide shaft 13 at the outside of the front side guide wheel 11, and the rear side guide wheel 12 are linearly wound up by the wire cable 8 and hence, the device can be simply and easily equipped. |
