Abstract: An electric steering apparatus for a vessel propulsion apparatus includes a steering motor, a lock clutch, and a rotation stopper mechanism. The steering motor generates a driving force to turn the steering shaft joined to an outboard motor. The lock clutch transmits a driving force from an input shaft to an output shaft when a forward input to transmit a driving force from the steering motor is generated, and shuts off the driving force transmission from the output shaft to the input shaft when a reverse input to transmit a driving force from the steering shaft is generated. The rotation stopper mechanism is configured to switch between a lock state in which the rotation stopper mechanism restricts rotation of the casing and a release state in which the rotation stopper mechanism releases the rotation restriction of the casing.
