Abstract
In a power tilt device, an opening/closing valve is arranged in a free piston, and an operating member is arranged within a piston rod of a piston and piston rod assembly contained within a closed cylinder. The operating member contacts a supply of hydraulic fluid from an opposite piston side space of a free piston to a first chamber above the piston by opening the opening/closing valve when coming into contact with an end wall of the cylinder during an upward tilting phase of the boat motor. Upon contact, the piston rod is extended outside of the cylinder causing a discharge of hydraulic fluid from the first chamber to an external reservoir, during which time the piston side space and the opposite side space of the free piston are fluidly interconnected.
