  • Patent number: 11504287
    Abstract: An electric vehicle includes: a mobile base capable of traveling by an electromotive drive; a seat including a seating portion having a sitting surface; and a battery capable of supplying electric power used in the electromotive drive. The seating portion of the seat includes a receiving portion capable of receiving the battery and arranged on a seat lower side with respect to the sitting surface. The mobile base is changeable between an expanded state in which a wheelbase is expanded and a contracted state in which the wheelbase is more contracted than in the expanded state. The seat is movable between a sitting position that the sitting surface faces a vehicle upper side in an expanded state of the mobile base, and a retracted position that the seating portion is retracted from the sitting position to a vehicle front side in a contracted state of the mobile base.
