Claims

[Claims for Utility Model Registration] A main drum for winding and simultaneously unwinding the wire means is disposed within the case of the wire drive means, and is arranged coaxially with the main drum, locks one end of the wire means, and also supports a balance spring. A sub-drum is rotatably biased in a direction to extend the wire means by a reaction force, and a brake shoe that rotates together with the handle shaft to control the rotation of the handle shaft is brought into contact with a protrusion protruding from the main drum in the rotational direction. In the window regulator which rotates the main drum by making contact with the wire means and raises and lowers the window glass via the wire means, the main drum includes a hanger bushing having a protruding part in the center thereof which comes into contact with the brake shoe. It is fitted movably in the axial direction of the handle shaft to transmit the rotation of the handle shaft to the main drum, and also slides and loosens on the contact surface of the hanger bush and sub-drum in the direction of wire extension. In the direction, the first and second
While forming a ratchet or serration,
A one-way clutch mechanism is constructed by disposing a coil spring that urges the hanger bush in a direction in which the first and second latches and serrations engage with each other, and the hanger bush that fits into the main drum protrudes from the main drum. A dowel is provided on the upper surface of the main drum on the brake shoe side adjacent to the protrusion, and the dowel is used as a brake shoe when the handle shaft rotates when the protrusion of the hanger bush comes into contact with the brake shoe of the handle shaft. A wind regulator for an automobile, characterized in that the first and second ratchets and serrations of the hanger bush and the sub-drum are engaged with each other by engaging with the main drum and pressing the main drum toward the sub-drum.
