PROBLEM TO BE SOLVED: To provide a marine gear device 11, in which a pressure reducing valve 65 is configured to have a high rigidity so that it can endure a high hydraulic fluid pressure during normal navigation so as to solve problems of increases in the weight and size of the pressure reducing valve 65, which may cause an increase in manufacturing costs.SOLUTION: A lubricant passage 42 for filling a forward/reverse selector mechanism 16 with lubricant is branched from a hydraulic fluid passage 24 that extends from a hydraulic fluid pump 21 to a forward/reverse selector mechanism 16 via a forward/reverse selector valve 26. A low pressure fluid passage 63 is branched from the lubricant passage 42. The low pressure fluid passage 63 is provided with a trolling device 64 for controlling a hydraulic fluid pressure flowing to the forward/reverse selector mechanism 16. In the hydraulic fluid passage 24, the outlet side of the low pressure fluid passage 63 is joined between a branch part 42a to the lubricant passage 42 and the forward/reverse selector valve 26. At the junction part between the hydraulic fluid passage 24 and the low pressure fluid passage 63, there is provided a junction selector valve 80 for selecting for the forward/reverse selector mechanism 16 either introducing a hydraulic fluid pressure via the hydraulic fluid passage 24 or introducing a hydraulic fluid pressure via the low pressure fluid passage 63. |
