PROBLEM TO BE SOLVED: To provide an opening/closing driving device capable of preventing or avoiding pinching.SOLUTION: A slide door opening/closing driving device 1 includes a roller assy 5 comprising a main roller 501, a first connection member 511, a second connection member 512, and friction members 521, 522. Inner cables 4a, 4b are attached to the first connection member 511 and the second connection member 512, respectively. The friction members 521, 522 are provided so as to be movable between a resistance generation position for generating resistance between a guide rail 20 and the roller assy 5 and a resistance suppression position for suppressing generation of the resistance. In a steady state in which the inner cables 4a, 4b have predetermined tension, the friction members 521, 522 are positioned at the resistance suppression position by the tension of the inner cables 4a, 4b, and in an abnormal state in which the tension of the inner cables 4a, 4b is released, the friction members 521, 522 cause resistance between the guide rail 20 and the roller assy 5 to generate to thereby cause the speed of a slide door 101 to be equal to or lower than safe speed.SELECTED DRAWING: Figure 4 |
