Electric power steering device

An electric power steering device, comprising:

• a motor;
• and
• a control unit provided on a non-output side in an axial direction of an output shaft of the motor to be integrated with the motor,
• the control unit including:
• a power module including a plurality of switching elements configured to supply current to motor windings of the motor;
• a control board configured to output a control signal to each of the plurality of switching elements;
• a heat sink, to which the power module is mounted, and is configured to release heat generated in the plurality of switching elements;
• a housing forming an outer case of the control unit;
• a power supply connector;
• and
• a signal connector,
• wherein the control board is provided in parallel to the axial direction of the output shaft,
• wherein a projection is formed at a bottom portion on the non-output side of the housing so as to protrude to the non-output side,
• wherein a non-output side end portion of the control board is inserted into the projection,
• wherein the power supply connector and the signal connector are provided in a region of an outer wall surface of the bottom portion spaced from the projection,
• wherein a hole is formed to pass through the bottom portion, and
• wherein an extension terminal extending from a contact pin of at least one connector out of the power supply connector and the signal connector, and each of a plurality of relay terminals to be connected to the extension terminal, which extend from the control board and the power module, are led out to the non-output side through the hole and connected to each other.
