    摘要： An outboard motor includes a steering arm that turns around a centerline of a steering shaft together with the steering shaft, a steering actuator including a movable body that moves in a right-left direction, and a motion converter that converts a movement of the movable body in the right-left direction into a turning motion of the steering arm around the centerline of the steering shaft. The motion converter includes a bushing holder into which the steering arm is inserted in a front-rear direction and a bushing interposed between the steering arm and the bushing holder and including an outer surface provided with a pair of first sliding portions each including a convex arc-shaped vertical section that is perpendicular or substantially perpendicular to the right-left direction.

    摘要： An electric actuator comprises a housing and an output shaft reciprocatingly received by the housing. There is a screw assembly disposed within the housing and coupled to the output shaft. The screw assembly includes a plurality of annular rollers and a central screw received by the annular rollers. The annular rollers are rotatable about the central screw. There is a motor which includes a stator and a rotor. The rotor has an inner bore which engages the annular rollers. Rotation of the rotor causes the central screw to translate axially relative to the rotor and the output shaft to reciprocate relative to the housing.
