Claims

[Scope of utility model registration request]

A pressure reducing valve through which hydraulic oil passes is interposed in series between a hydraulic pressure regulating valve and a switching valve in the hydraulic oil passage to the hydraulic clutch which is interposed between the propeller thrust shaft and the input shaft and is slip-controlled. In a marine speed reducer, the pressure reducing valve has a hydraulic oil port, a hydraulic oil main passage port, and a drain port provided in the valve body, a pressure regulating spool housed in the valve body that opens and closes the port, and a pressure regulating spool on the same spool. An operating spool coaxially slidably disposed via a spring, a piston chamber formed on the opposite side of the pressure regulating spool to the operating spool disposed side, and the hydraulic oil inflow port on the pressure regulating spool. A trolling device for a marine speed reducer, comprising an orifice drilled to communicate with the piston chamber.
