Each trim cylinder is pivotally supported on the stern bracket, and a rear end of each trim cylinder is provided with thrust rollers which rolls on the lift member. Alternatively, each trim cylinder is pivotally supported on the lift member, and the front end is provided with the thrust rollers abutting against the stern bracket.
