Steering device for outboard engine

A steering shaft (22) is provided to the case (21) of a helm device (20). The rotation of the steering shaft (22) is detected by a helm sensor (25). A friction generation mechanism (23) is provided within the case (21). The friction generation mechanism (23) includes: a rotation body (70) provided to the steering shaft (22); inner discs (71) rotating integrally with the rotation body (70); outer discs (72) facing the inner disc (71); an electromagnetic actuator (73); and an armature (74) driven by the electromagnetic actuator (73). An assist spring (24) is disposed within the case (21). The assist spring (24) presses the armature (74) in the direction in which the discs (71, 72) are pressed against each other.
