A small-sized vehicle has a structure that enables reductions in the number of assembly steps and that improves the sealing property of a connecting portion without causing a cost increase. The small-sized vehicle includes a floor panel having a foot panel portion on which an occupant places his/her feet and a front panel portion arranged to extend upwardly between a suspension system and the legs of the occupant, the foot panel portion and the front panel portion being integrally formed of resin, and the floor panel made of resin is arranged and fixed on a vehicle body frame.
