Patent attributes
An object of the present invention is to provide a trolling device which can reduce the operational force of a trolling lever while the oil pressure setting of a marine gear is raised to increase the capacity of a transmission torque. The trolling device has a pressure reducing valve 23 for reducing clutch oil pressure and a low speed valve 22 for adjusting the spring force of a pilot spring 24 of the pressure reducing valve 23 in conjunction with a trolling lever 25, the low speed valve 22 having a protrusion 22a which extends inside a coil spring constituting the pilot spring 24 to the side of the pressure reducing valve 23 and comes into contact with the pressure reducing valve 23 at least when forward and reverse clutches are fully engaged, the protrusion 22a having a drain oil passage 22c which comes into communication with an orifice 23c when in contact with the pressure reducing valve 23 during trolling and discharges drain oil from the orifice 23c.
