PROBLEM TO BE SOLVED: To provide a non slip guide allowing a ball chain non slip hood part 3 to surely come to the upper part of a driving sprocket 4 whichever direction a window opening/closing device 6 is installed, and moreover operable silently. SOLUTION: This ball chain non slip guide is formed by integrally molding a base plate 2 mounted between a body cover surface 10 of the window opening/closing device 6 and the driving ball chain sprocket 4, and the non slip hood part 3 whose position is designed to further have a clearance from the upper face. The base plate 2 is provided with a through hole 8 for a driving shaft and formed with mounting holes 9 to be mountable so that the hood part 3 always comes into the upper position of the ball chain sprocket 4. Both ends of the hood part 3 are in positions where the ball chain does not come in contact even if the ball chain 5 is pulled at a predetermined speed to rotate the ball chain sprocket normally and reversely.
