Electric steering apparatus for vessel propulsion apparatus, and vessel propulsion apparatus

摘要

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.

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.
