切換機構。[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 driven gear or to the propeller shaft via the reverse driven gear; a clutch actuating rod that is arranged to be reciprocally movable and reciprocates the movable clutch member in the axial direction of the propeller shaft; a clutch actuating rod drive means that reciprocates the clutch actuating rod in the axial direction of the propeller shaft; The clutch actuating rod includes an operating rod whose tip is connected to the clutch actuating rod drive means, and an operating force transmitting mechanism that is connected to the operating rod and transmits the operating force of the operating lever to the operating rod, and the operating force transmitting mechanism is connected to the upper cowling. In the forward/reverse switching mechanism of the outboard motor, the operating force transmission mechanism is configured to transmit the operating force when the clutch movable member is engaged with the forward driven driven gear, and when the clutch movable member is engaged with the reverse driven gear. A forward/reverse switching mechanism for an outboard motor, characterized by having an impact force absorbing link that absorbs the impact force generated when the outboard motor is rotated.
