Claims

[Claims for Utility Model Registration] A drive gear fixed to the tip of a drive shaft, a forward driven gear that is always in mesh with the drive gear and rotatably fitted on the propeller shaft, and a forward driven gear that is always in mesh with the drive gear and rotatably fitted in the propeller shaft. a reverse driven gear rotatably fitted to the propeller shaft; and a reverse driven gear fitted to the outer periphery of the propeller shaft at a portion between the forward driven gear and the reverse driven gear so as to be movable in the axial direction thereof; a clutch movable member for switching between transmitting the rotational force of the drive gear to the propeller shaft via the forward drive gear or to the propeller shaft via the reverse drive gear; a push rod that is arranged to be reciprocally movable and that reciprocates the clutch movable member in the axial direction of the propeller shaft; a push rod drive cam that reciprocates the push rod in the axial direction of the propeller shaft; and a push rod drive cam that moves the push rod. a spring that presses against the cam surface of the push rod, an operating rod whose tip is fixed to the push rod drive cam, and an operating force transmission mechanism that is connected to the operating rod and transmits the operating force of the operating lever to the operating rod, In a forward/reverse switching mechanism for an outboard motor, the operating force transmission mechanism is disposed in an upper cowling, and the operating force transmission mechanism engages the clutch movable member with the forward driven gear or engages the reverse driven gear. Forward and reverse movement of an outboard motor, characterized by having an impact force absorbing link that absorbs an impact force generated when the push rod is engaged with the push rod in a direction in which the push rod is pressed against the push rod drive cam. Switching mechanism.
