Abstract
A brushless motor comprises a casing including an axle seat with an axle hole, the axle hole having a flange provided therein. An axle tube is engaged on the axle seat and includes a bearing mounted therein for rotatably holding a shaft of a rotor. The shaft includes a distal end that extends beyond an end face of the bearing, the distal end including a neck to thereby define an annular groove. An engaging member mounted in the axle hole of the axle seat and retained in place by the bearing or the axle tube. The engaging member includes a hole having an inner diameter smaller than a diameter of the shaft of the rotor. An inner peripheral wall defining the hole of the engaging member includes a plurality of notches to thereby allow forcible passage of a distal end of the shaft through the hole of the engaging member. The peripheral wall of the hole of the engaging member is located in the annular groove of the shaft after the distal end of the shaft is passed through the hole of the engaging member.
