Title:
DISC BRAKE
Document Type and Number:
WIPO Patent Application WO/2011/037232
Kind Code:
A1
Abstract:
A disc brake configured in such a manner that the position of a return spring at which the return spring is in contact with a mounting member side is prevented from being largely displaced due to the wear, etc, of the friction pad. A return spring for pressing a friction pad in the direction in which the friction pad is separated from a disc comprises: an affixed section which is located on one side of the return spring and is mounted and affixed to the friction pad; an extended section which is extended from the affixed section in the axis direction of the disc so as to be separated from the friction pad; a turned-back section which is formed by turning back the tip side of the extended section to the mounting member side; and a contact section which is provided to the tip side of the turned-back section and makes elastic contact with the mounting member side. The portion (bend section) of the turned-back section which is formed by bending the turned-back section at the middle thereof is located at a position further from the affixed section than the contact section in the rotational direction of the disc.
