Title:
ELECTRIC PARKING BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/187361
Kind Code:
A1
Abstract:
In an electric parking brake device configured in such a way that a parking brake state resulting from pulling of a brake cable is released by loosening the brake cable, the brake cable (37) is formed by twisting together a plurality of wires (92) in such a way as to generate a twisting force in a fixed direction when pulled, and the direction in which the twisting force generated by the brake cable (37) in a pulled state acts on a screw shaft (38) is set to be the same direction as the direction in which a nut (61) is rotated to loosen the brake cable (37). This makes it possible to reduce an operating sound and to reduce wear of members constituting a rotation restricting means.
