An apparatus for measuring working load of an electrical parking brake in a vehicle is provided to calculate a precise load by allowing a spring to be compressed in an initial installation state such that the spring is prevented from exhibiting a non-linear behavior in a low-load range. An apparatus for measuring working load of an electrical parking brake in a vehicle comprises an actuator unit(1), an equalizer(14) and a load-measuring unit(9). The load-measuring unit includes a casing(10) forming a receiving space(10a), a tap shaft(6b), an equalizer connection shaft(8), a movable press member(11), a spring(13) disposed between the movable press member and the receiving space, and a sensing member(12) including a hall IC(12b). The tap shaft is formed at a connection end(6a) of a cable(15) to be coupled the casing. The equalizer connection shaft has a first end fixed to the equalizer and a second end inserted into the receiving space. The movable press member is connected to the equalizer connection shaft in the receiving space and moves by a pressing force of the tap shaft. The hall IC detects a magnetic member(12a) provided on the moving press member. |
