Abstract
A mechanism for tilting an outboard motor. The mechanism has an outboard motor which is attached to a hull so as to be tilted up and down, a cylinder for driving the outboard motor to change a posture of the outboard motor, and a linkage to connect the outboard motor and a rod of the cylinder. The cylinder itself serves as a central shaft, around which the outboard motor is tilted up and down. Since the cylinder has a single-walled construction, the mechanism of the present invention is simple and can be economically manufactured.
Claims3
A tilting mechanism for an outboard motor, comprising:
- an outboard motor which is attached to a hull so that the outboard motor can be tilted up and down;
- a cylinder for driving the outboard motor to change a posture of the outboard motor, the cylinder itself serving as a shaft about which the outboard motor can be tilted up and down;
- and
- a linkage to connect the outboard motor and a rod of the cylinder to each other,
- wherein the cylinder is single-walled, so that the cylinder comprises a tube which extends outside a piston fixed to the rod, and which contacts with an outer surface of the piston to form a first room and a second room on both sides of the piston, and
- wherein a first port supplying working fluid to the first room is located on one of ends of the cylinder near the first room, and a second port supplying working fluid to the second room is located on the other of the ends of the cylinder near the second room.
