Claims

[Claims for Utility Model Registration] A rotor is rotatably supported in a housing to which a circuit board is attached, an index is provided on the outer periphery of the rotor yoke of the rotor, and an index sensor for detecting this index is installed on the outer periphery of the rotor yoke. In the brushless motor, which is placed on the circuit board via a sensor holder whose position can be adjusted nearby, the sensor holder is made of an insulating material, and the same number of insulating passages as the terminals of the index sensor are provided in the brushless motor. A brushless motor characterized in that a solder connection portion between a terminal of a TUX sensor and a lead wire connected to the terminal via solder is housed in each of the insulating passages.
