A steering structure of an outboard motor is provided to have high reliability without functional deterioration. The steering structure includes a tilting shaft provided on a bracket device of the outboard motor to pivotally support the outboard motor in such a manner that the outboard motor can tilt vertically. A steering damper is disposed on the outboard motor, wherein the steering damper includes a damper cylinder and a piston rod that extends inside the damper cylinder and protrudes outwardly from the damper cylinder in a transverse direction. Openings at opposite ends of the damper cylinder are closed by a piston stopper, which slidably supports the piston rod and maintains the inside of the damper cylinder fluidtight, to form a fluid chamber. A damper piston is provided at the central portion of the piston rod in the fluid chamber to partition the fluid chamber into right and left chambers. The right and left fluid chambers are communicated with each other by a bypass pipe, and a throttle valve is disposed intermediate the ends of the bypass pipe.
