Abstract: A drum brake used in a vehicle generally includes a backing plate secured to a non-rotatable member of a wheel shaft; a pair of brake shoes slidably attached to the backing plate; a wheel cylinder disposed between each end portion of the brake shoes where they are closely positioned to each other; and a substantially U-shaped return spring to be engaged with each web portion of the brake shoes at the extreme ends thereof for biasing both in a mutually approaching direction. The U-shaped return spring in this invention is characteristically provided with, at each end portion thereof, where the same is engaged with each web portion of the shoes, a notch whereinto the web portion is to be fitted for securely positioning the return spring.
