In a steering handle grasped and rotated by both hands of a driver, an axis of a steering shaft included in the steering handle is inclined so as to be higher in level in a forward direction of a vehicle body, and a left grip grasped by a left hand and a right grip grasped by a right hand are rotatable in opposite directions about an axis perpendicular to the axis of the steering shaft. Accordingly, an upper half of the driver's body sitting on a seat and leaning backwards and a plane of rotation of the steering handle are substantially parallel to each other, thereby ensuring that the driver can rotate the steering handle without stretching and withdrawing his or her arms. Moreover, when the steering handle is rotated, the driver's wrists can be prevented from being twisted unnaturally, leading to an easy steering operation.
