## Abstract

A disk brake device has a first component, a universal set, and a second component. The first component has a first assembling hole axially formed through the first component. The universal set is mounted in the first assembling hole and has a base having a supporting protrusion and a first clutch. The first clutch has a fixed plate and a movable plate. The fixed plate has a flange embedded in and fixed to the first assembling hole. The movable plate is capable of axially reciprocating and has a feeding shaft and a recess. The feeding shaft is mounted through the fixed plate. The recess is mounted on the supporting protrusion and contacts the supporting protrusion in a point-contact relationship. The second component is fastened to the first component and has a second assembling hole formed through the second component and assembled by a second clutch.
