Patent number: 7627989Abstract: A drive device for a wire-type window regulator is disclosed wherein a drum is accommodated in a cover and, under such a status, rotating and operating a rotation operator, exposed to an operation bore portion, enables work to be done for winding a wire. With the rotation operator kept in engagement with operation bore portion, the drum is avoided from rotating in a rewinding direction, making it easy to perform work for an output shaft of a motor to be brought into engagement with a drive bore portion of the drum.Type: GrantFiled: April 14, 2005Date of Patent: December 8, 2009Assignee: Ohi Seisakusho Co., Ltd.Inventors: Yasuo Ootsuki, Hisato Tatsumi
