A cross section of the main frame in a direction crossing a vehicle body forward/rearward direction is formed in a substantially rectangular shape having a vertical width larger than a lateral width. A carbon fiber reinforced resin in which carbon fibers are oriented uniformly in the vehicle body forward/rearward direction is installed on at least one of upper surfaces and lower surfaces of the main frames.
