Claims

[Scope of utility model registration request]

The tilt/outboard motor is designed to communicate between two oil chambers in the cylinder defined by the piston and the tank by moving the manual valve body fitted in the valve block so that it can move forward and backward.
In the manual valve mechanism of the trim device, each port of two oil chambers is formed in the valve block with a tank port in between, and a check valve is inserted between the tank port and one of the oil chamber ports in the valve block. A check valve is interposed in the manual valve body between the tank port and the port of the other oil chamber, and a spool is movably interposed between each of the check valves. Manual valve mechanism for tilt and trim device.
