OUTBOARD MOTOR

摘要

An outboard motor includes a drive shaft that transmits rotational power from the engine, and a shift unit provided in the middle of the drive shaft. The shift unit has a dog clutch that reciprocates in parallel with the drive shaft, a shift fork member that reciprocates the dog clutch in parallel with the drive shaft, and a linear motion type actuator that reciprocates the shift fork member in parallel with the drive shaft. The actuator is arranged in the vicinity of the front side of the dog clutch such that the direction of the rectilinear motion of the screw shaft is in parallel with the axial line of the drive shaft, and the shift fork member is connected to the screw shaft.

1. An outboard motor comprising:
an engine; a drive shaft vertically extending from the engine to transmit rotational power from the engine; and a shift unit provided in the middle of the drive shaft to switch a shift position, wherein the shift unit has
a clutch body that switches the shift position by reciprocating in parallel with the drive shaft,a shift fork member engaged with the clutch body to reciprocate the clutch body in parallel with the drive shaft, andan actuator that reciprocates the shift fork member in parallel with the drive shaft, the actuator is a linear motion type in which a drive force output member for outputting the driving force makes a rectilinear motion and is arranged in the vicinity of the front side of the clutch body such that a direction of the rectilinear motion is in parallel with an axial line of the drive shaft, and the shift fork member is connected to the drive force output member.
