PURPOSE:To prevent smoothness of opening and closing of a door from being spoiled by sticking of water or an installing time error or the like. CONSTITUTION:A driven plate 4 extending in the width direction of a door is fixed to an inner panel 32 of a sliding door, and a rack plate 6 composed of a hard rubber material is joined to this. A driving roller 1 to be reciprocally rotated by a motor is composed of an inner peripheral part 11 of a soft rubber material and an outer peripheral part 12 of a hard rubber material, and a large number of tooth shapes 13 are formed in the circumferential direction in the outer peripheral part 12. In a condition where the driven plate 4 is sandwiched by the driving roller 1 and a guide roller 2, the tooth shapes 13 of the driving roller 1 are meshed with tooth shapes 61 of the rack plate 6. |
