Abstract

A brushless motor includes a stator having a stator core, a rotor, a circuit board, a board holder for holding the circuit board, a motor housing having a notch at an opening, and a housing cover. The motor housing accommodates the stator, the rotor, and the board holder to which the circuit board is mounted, and the motor housing is sealed with the housing cover. The board holder includes a board mount section, a lead-wire holder for holding lead-wires. The lead-wire holder is placed at the notch of the motor housing. The lead-wires extend from the circuit board mounted to the board mount section to the outside of the motor housing via the lead-wire holder.
