Abstract
A snowmobile includes steering handlebars, a pair of left and right skis, and a power transmission mechanism arranged to couple the steering handlebars and the skis. The power transmission mechanism includes a first rotary shaft extending directly downward or obliquely downward from the steering handlebars for rotation along with the steering handlebars; a first link mechanism coupled to the first rotary shaft; a second rotary shaft coupled to the first link mechanism and arranged to rotate along with the rotation of the first rotary shaft via the first link mechanism, the second rotary shaft being disposed on a different axis from that of the first rotary shaft; a second link mechanism disposed between the second rotary shaft and the skis; and a power steering device mounted to the second link mechanism as a part thereof and having an actuator to be driven based on the rotation of the second rotary shaft.
