Method for manufacturing a motor having a control circuit board

A method for manufacturing a motor, the method comprising:

• installing a gear of a speed reducing mechanism into a gear housing;
• installing a control circuit board, which has an external connector adapted to be directly, detachably connectable with a separate connector outside of the motor to receive electrical power, to the gear housing in a first direction such that a circuit board side connector of the control circuit board is electrically connected to a main body side connector for the first time at the time of installing the control circuit board to the gear housing, wherein the gear housing is joined to a motor main body, and wherein the main body side connector is attached to the gear housing;
• releasably fixing the control circuit board to the gear housing by a fixing means to prevent movement of the control circuit board relative to the gear housing in a second direction, which is opposite from the first direction;
• and
• installing a circuit board receiving case to the gear housing in the first direction after the installing of the control circuit board to the gear housing such that a gear housing side opening of the circuit board receiving case is connected to the gear housing to receive the control circuit board into the circuit board receiving case through the gear housing side opening of the circuit board receiving case,
• wherein the installing of the circuit board receiving case to the gear housing is performed such that the external connector of the control circuit board sticks out of an external connector opening in the circuit board receiving case in the second direction.
