ABSTRACT:
A mechanical disc brake, including a caliper supported on a stationary member to slide in the direction of the axis of rotation of a rotatable disc and straddling the circumference of the disc to define two limb portions on the opposite sides of the disc, a first friction pad being pressed against one surface of the disc by one of the limb portions, a second friction pad disposed so as to be opposed to the first friction pad and being pressed against another surface of the disc, a force converting mechanism provided in the other limb portion of the caliper for converting the rotation of a lever to thrust force pressing the second friction pad, a rod extending in the direction of the axis of the disc and threadingly engaging the force converting mechanism with one end thereof engaging the second friction pad, a spring retainer threadingly engaging the other end of the rod, and a coil spring acting between the spring retainer and the other limb portion of the caliper to bias the rod in the direction separating from the second friction pad. A projection is provided on the spring retainer for abutting in the circumferential direction one end of the coil spring, thereby controlling the rotation of the spring retainer with respect to the rod.
