Abstract:
1. An electric steering apparatus for a vessel propulsion apparatus, the electric steering apparatus comprising: a steering motor configured to generate a driving force to turn a steering shaft joined to an outboard motor; a lock clutch including an input shaft to which rotation is transmitted from the steering motor, an output shaft configured to transmit the rotation transmitted to the input shaft to the steering shaft, and a casing configured to rotatably hold the input shaft and the output shaft, the lock clutch being configured to transmit a driving force from the input shaft to the output shaft when a forward input in which a driving force is transmitted from the steering motor to the steering shaft is generated, and to transmit a driving force from the output shaft to the casing so as to shut off a driving force transmission from the output shaft to the input shaft when a reverse input in which a driving force is transmitted from the steering shaft to the steering motor is generated; and a rotation stopper mechanism 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 a rotation restriction of the casing.
