PROBLEM TO BE SOLVED: To provide an electric slide door with no jump or breakage of teeth by completely engaging a toothed belt with a toothed pulley to tow the slide door. SOLUTION: Guide rollers 17, 18 arranged corresponding to the engagement start position (x) and the engagement finish position (y) of an endless toothed belt 16 engaged with a toothed pulley 15 are used to completely engage the toothed pulley 15 with the endless toothed belt 16 therebetween. Even if the endless toothed belt 16 is loosened, there are no jump or breakage of teeth. Smooth drive and transmission are thus allowed for a slide door to be smoothly opened/closed. |
