チルト装置。 In a hydraulic trim/tilt device in which a tilt cylinder unit and a trim cylinder unit are operated by hydraulic fluid from a single hydraulic source, the trim cylinder unit is a cylinder defined by a piston. The two oil chambers within the piston are communicated by an oil passage formed in the piston or the piston rod, and a relief valve biased in the closing direction by a spring is provided in the oil passage, and furthermore, the piston rod is in contact with the propulsion unit. A hydraulic trim is characterized in that a push rod is inserted through the push rod which slides in a direction to compress the spring.
Tilt device.
