Abstract: A motor unit for use in electric bicycles, the motor unit comprising: a motor having a rotary shaft; a unit case to house the rotary shaft partially; an input shaft arranged in the unit case to penetrate through the unit case and to be rotatable around an axis; an input body configured to rotate along with the input shaft; an output body configured to rotate around the axis upon receiving rotational force of the input body; and a control board housed in the unit case and configured to control rotation of the motor. The unit case includes: a first heat dissipating portion connected to a first surface of the control board; and a second heat dissipating portion connected to a second surface opposite from the first surface of the control board.

Abstract: A motor unit includes a substrate, a motor, and at least one conductive member. The substrate has a first surface and a second surface aligned in a thickness direction of the substrate. The motor includes at least one terminal, and in the thickness direction of the substrate, the motor is disposed closer to the second surface than to the first surface. The at least one conductive member is mounted on the first surface. The substrate has at least one through part which extends from the first surface through the second surface and in which the at least one terminal or the at least one conductive member is inserted. The at least one conductive member is at least partially deformable and is connected to the at least one terminal.
