Claims

[Claims for Utility Model Registration] A main drum for winding and unwinding the wire means within the case of the wire driving means, and a main drum arranged coaxially with the main drum, locking one end of the wire means, and 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 is brought into contact with a protrusion protruding from the main drum in the rotational direction. In the wind regulator which rotates the main drum and raises and lowers the window glass via the wire means, the main drum has a hanger bushing having a protrusion in its center that abuts the brake shaft, and the hanger bush is connected to the shaft of the handle shaft. The one-way wire is fitted so as to be movable in the direction to transmit the rotation of the handle shaft to the main drum, and also slides around the hanger bushing and sub-drum in the direction in which the wire extends, and engages with each other in the direction in which the wire loosens. A one-way clutch spring mechanism is provided in which a clutch spring is arranged, and a coil spring biases the hanger bushing toward the sub-drum. A pair of dowels are provided on the upper surface of the drum, and first and second ratchets and serrations are provided on the contact surface between the main drum and the sub-drum,
When the handle shaft is rotated, in which the protrusion of the hanger bushing comes into contact with the brake shoe of the handle shaft, the dowel is engaged with the brake shoe;
A wind regulator for an automobile, characterized in that the first and second ratchets and serrations are configured to mesh with each other.
