Manual opening and closing structure of the invention opening and closing device for windows according to the manual opening and closing of the opening and closing device for a window formed as being provided between the in the power opening and closing apparatus for power opening the window to the power of the motor, the drive shaft is rotated in the power of the motor and a driven shaft in the structure, the number of rotation, which is installed on the drive shaft that is rotated by power of the motor member, and provided with a first tooth on the inner surface to the distal end portion of the rotary member the first clutch member, the front end portion of the rotary member and a plurality of second one of the plurality, each binding the rear end of the clutch member bolts, by having a plurality of driven clutch teeth on a plurality of elastic members, and outer circumferential surfaces are interposed respectively on the bolt, each of the elastic support the rear end of the first plurality of clutch member is meshed with the first plurality of teeth of the first clutch member a plurality of first clutch member and the spline-coupled to the driven clutch member comprised soon as well as being installed on the end of a driven shaft which is disposed in a straight line and the driving shaft.
Accordingly, the present invention does not manually open and close operation is the wear of the clutch structure caused even if degraded, because the driven clutch teeth of the first teeth of the first clutch member and a driven clutch member being splined structure severely binding force of the clutch structure due to the window smooth the power opening and closing of the make, yet can be manually easily opening and closing the window, for a long time the first clutch member and a driven clutch member even if degradation occurs serious binding force by tightening the bolt can be easily enhance the elastic force of the elastic member of the clutch structure needs to be replaced is not.
