Abstract:
An outboard motor comprising a power transmission mechanism transmitting the
power of an engine to a propeller. The transmission unit of the power transmission
mechanism comprises a one row of planetary gear train for transmission having
a sun gear for transmission, planetary gears for transmission, and an internal
gear for transmission. The internal gear for transmission is connected to an
engine side input shaft, the planetary gears for transmission are connected
to a propeller side output shaft, the sun gear for transmission is connected to
a fixed part through a one-way clutch, and the planetary gears for transmission,
the internal gear for transmission, and/or the sun gear for transmission are
connected to each other through an engagement/disengagement clutch. Accordingly,
when the engagement/disengagement clutch is disengaged, the one-way clutch
is engaged, and the speed of the input shaft is reduced and output from the output
shaft. When the engagement/disengagement clutch is engaged, the one-way clutch
is disengaged, and the speed of the input shaft is output from the output shaft
at a same speed.
