Abstract
An electric outboard motor for propelling a boat. The electric outboard motor includes an outer case provided at a lower portion of the electric outboard motor and having a cylindrical portion formed in a cylindrical shape with an axis extending in a front-rear direction, a propeller rotatably supported on the outer case; and a motor provided inside the cylindrical portion and configured to rotate the propeller. The motor includes an output shaft extending in the front-rear direction, a rotor provided on an outer periphery of the output shaft, a stator provided on an outer periphery of the rotor, and a motor case in which the output shaft, the rotor, and the stator are disposed, the motor case being formed in a cylindrical shape having an axis extending in the front-rear direction.

An electric outboard motor for propelling a boat, the electric outboard motor comprising:
- an outer case provided at a lower portion of the electric outboard motor and having a cylindrical portion formed in a cylindrical shape with an axis extending in a front-rear direction;
- a propeller rotatably supported on the outer case;
- and
- a motor provided inside the cylindrical portion and configured to rotate the propeller,
- wherein the motor includes:
- an output shaft extending in the front-rear direction;
- a rotor provided on an outer periphery of the output shaft;
- a stator provided on an outer periphery of the rotor;
- and
- a motor case in which the output shaft, the rotor, and the stator are disposed, the motor case being formed in a cylindrical shape having an axis extending in the front-rear direction,
- a fixing portion is provided on the motor case, the fixing portion being disposed on one side of the stator in the front-rear direction and overlapping with the stator when the motor is viewed from the one side in the front-rear direction,
- a protrusion is provided on the cylindrical portion, the protrusion protruding inward from an inner peripheral surface of the cylindrical portion to a position overlapping with the fixing portion of the motor provided inside the cylindrical portion when the cylindrical portion is viewed from the one side in the front-rear direction, and
- the motor is fixed to the outer case by connecting the fixing portion to the protrusion.
