1. A parking brake apparatus for a vehicle, comprising:
a motor section receiving electric power from an outside, and generating power;
a power transmission section rotated by driving the motor section, and including transmission worm gears;
a pair of pressing units receiving power from the power transmission section and pressing a brake pad;
a load transmission unit installed between the pair of pressing units, connected to each of the pair of pressing units, transmitting a pressing load of any one of the pair of pressing units to the other pressing unit, and made of a magnetic material;
a magnet unit disposed to be spaced apart from the load transmission unit and configured to generate a magnetic field in the area of the load transmission unit; and
a hall sensor unit disposed between the load transmission unit and the magnet unit, and sensing a change in the magnetic field according to rotation of the load transmission unit,
wherein the load transmission unit includes gears for transmitting the pressing load, the magnet unit is disposed to face the gears of the load transmission unit, and the hall sensor unit is configured to determine abnormal operation of the load transmission unit based on a change in the magnetic field corresponding to a change in rotation of the gears of the load transmission unit.
