PROBLEM TO BE SOLVED: To provide a snowmobile which ensures a strength and a rigidity of a tunnel part made of a carbon fiber reinforced plastic without installing a metal frame.SOLUTION: A snowmobile comprises a vehicle body frame comprising a tunnel part 80 extending in the vehicle longitudinal direction, with the tunnel part 80 comprising: an upper wall 81U made of a carbon fiber reinforced plastic; a left side wall 81L made of a carbon fiber reinforced plastic; a right side wall 81R made of a carbon fiber reinforced plastic; a left reinforcement member 83L which reinforces the left side wall 81L and is made of a carbon fiber reinforced plastic; a right reinforcement member 83R which reinforces the right side wall 81R and is made of a carbon fiber reinforced plastic. A first closed cross section 85L is constituted of the upper wall 81U, the left side wall 81L and the left reinforcement member 83L, and a second closed cross section 85R is constituted of the upper wall 81U, the right side wall 81R and the right reinforcement member 83R.SELECTED DRAWING: Figure 17 |
