PURPOSE: An apparatus for detecting a position of a rotator in a brushless motor is provided to install easily a position detection sensor by simplifying an assembling and disassembling structure of the brushless motor. CONSTITUTION: A motor casing(11) has a predetermined space. A stator is fixed to the inside of the motor casing(11). A rotator is formed in the inside of the stator. A motor shaft(14) is formed at a center portion of the rotator in order to transmit rotary power. A position detection portion is installed at the outside of the motor casing(11). The position detection portion is formed with a plurality of position detection magnets(15a), a position detection sensor(15b), and a sensor support member(15c). The position detection magnets(15a) is installed at one end portion of the motor shaft(14). The position detection sensor(15b) is installed at the outside of the motor casing(11). The sensor support member(15c) is installed at the outside of the motor casing(11).
