Abstract

An apparatus for automatically controlling the tension of a cable of a parking brake is provided. The apparatus includes a housing that is moved upon the manipulation of the manipulation lever and includes a first inclined surface that is formed on an inner surface of a first end of the housing; a rod that passes through the housing and includes teeth that are formed on a portion of the rod in the housing; a first elastic member that is disposed on one side of the housing and is penetrated by the rod; a rod holder that is connected to the rod and supports the first elastic member; a second elastic member that is disposed in the housing and is penetrated by the rod; a tension control module which is disposed in the housing, is penetrated by the rod, is connected to the second elastic member so as to be able to move along the rod due to an elastic force of the second elastic member, and includes teeth and a plurality of second inclined surfaces that define an outer circumferential surface of one end of the tension control module and that correspond to the first inclined surface, wherein, if the first inclined surface contacts the second inclined surfaces, the tension control module is moved toward the rod so that the teeth of the tension control module can engage with the teeth of the rod; a cable stopper that is penetrated by the rod and is inserted into the housing so as to be able to move along the rod; and a stopper that is fixed to an exterior of the housing and prevents movement of the cable stopper.
