OUTBOARD MOTOR SHIFT ACTUATOR

摘要

According to one embodiment, a shift actuator includes a main body section and a shaft section. The main body section has an electric motor which has a vertically extending rotating shaft, and a gear mechanism which rotates the shaft section in accordance with the rotating shaft. The shaft section has a threaded shaft extending parallel to the rotating shaft and made to rotate by the gear mechanism in accordance with the rotating shaft and a movable nut which is screwed onto the threaded shaft and moves upward or downward with rotation of the threaded shaft. The movable nut is connected with a shift member which changes the gears of a propeller shaft.
