Abstract: A steering handle device includes a housing to be mounted on a hull, a tube member and a steering shaft. The tube member is rotatable in a forward/backward direction around the tilt shaft relative to the housing. The steering shaft is inserted to the tube member. A steering arm is attached to the steering shaft. The steering arm includes an extending portion extending to an outer side of the housing. A joint member is provided on the extending portion. The joint member includes a connection portion to connect to the steering cable and a support portion to support the connection portion. When the steering shaft is in the neutral position in the rotation direction, the connection portion is located in a position corresponding to the tilt shaft as viewing the housing from the lateral direction.
