置。 In a tilt/trim device that rotates an outboard motor up and down by supplying and discharging hydraulic oil from a tank to a hydraulic cylinder unit via a spool valve using a pump, the lower chamber side of the cylinder from the pump to the spool valve. A trim relief valve and a throttle valve are interposed in series between the flow path and the reservoir tank, and the opening pressure of the trim relief valve is lower than the opening pressure of the lower chamber relief valve, and the opening pressure of the trim relief valve is lower than the opening pressure of the lower chamber relief valve. A tilt/trim device for an outboard motor, characterized in that the pressure is set to open the valve when thrust is received and close the valve when the tilt is activated.
