PROBLEM TO BE SOLVED: To prevent occurrence abnormal sound by enlarging and deforming a coil spring when an opening torque for a window glass is input from a pinion side. SOLUTION: First and second notches 11a, 11b are formed in a drum 11 and first and second engaging parts 12a, 12b are bent and formed in a support 12. When an opening torque for a window glass is input from a pinion 6 side, the side edge b of the second engaging part 12b of the support 12 comes into contact with the side edge b of the second notch 11b of the drum 11. Then, both side edges a, b of the first engaging part 12a do not come into contact with the bends 13a, 13b of a coil spring 13 and hence, a braking action is not generated between the coil spring 13 and the inner peripheral face of the cover. In this way, abnormal sound is prevented on opening the window glass and the whole parts for manual operation and power window regulators except the support 12 can be used in common and hence, it is resulted in costdown. |
