Abstract
A snowmobile includes steering handlebars; a steering column attached to the steering handlebars and extending directly downward or obliquely downward; a power steering device having a motor and attached to the steering column; a power transmission mechanism arranged to transmit at least the driving force of the motor; and a ski coupled to the power transmission mechanism to be turned by the power transmission mechanism. The power steering device includes a sensor arranged to detect the rotation of the steering column. The motor has a motor shaft tilted from both the fore and aft direction and the left and right direction of the vehicle.
