Claims

[Scope of utility model registration request]

A case that also serves as a support member for supporting a reversing case 5 of a reversing machine 4 having an input shaft 3 connected to an engine flywheel 2 within the flywheel case 1 and one end side of a transmission mechanism within the reversing case 5. In a marine propulsion device that is connected and fixed to the flywheel case 1 through a cover 6, a wall 7 is provided on the reversing case 5 on the case cover 6 side, and one end side of the transmission mechanism is connected to the case cover 6. The engine flywheel 1. A marine propulsion device characterized in that a cooling air passage 8 is formed through which cooling air is conducted by the suction effect caused by the rotation of the vessel.
