Abstract: A personal watercraft comprises a body including a seat support section in which a storage is accommodated; a front seat which is mountable on the seat support section; a rear seat which covers the storage in a state in which the rear seat is secured onto the seat support section; an opening/closing mechanism including a pivot section provided at a front end portion of the rear seat and opens and closes the rear seat and a slider section which guides the pivot section and slides the rear seat in a rearward direction. In a closed state in which the front seat and the rear seat are secured onto the seat support section, a rear end of the front seat is located rearward of and above a front end of the rear seat, and the pivot section is located below and forward of the rear end of the front seat.
