The frame body defines an entrance opening which is located at a lateral side of the seat and through which an occupant passes when the occupant gets in and out of the vehicle. The seat support frame defines a battery passing opening which opens the under-seat space in a horizontal direction and has such a size that the battery can pass through the battery passing opening. ## Claims ### Claim 1 A vehicle comprising: a left wheel and a right wheel which are located with an interval in a vehicle left-right direction; a frame body including a floor frame and a seat support frame located at an upper side of the floor frame; a seat supported by the seat support frame from below; and a battery supported by the frame body, at least part of the battery being located in an under-seat space surrounded by the seat support frame and the floor frame, wherein: the frame body defines an entrance opening which is located at a lateral side of the seat and through which an occupant passes when the occupant gets in and out of the vehicle; and the seat support frame defines a battery passing opening which opens the under-seat space in a horizontal direction and has such a size that the battery passes through the battery passing opening. ### Claim 2 (depends on 1) The vehicle according to claim 1, further comprising a partition wall covering the under-seat space, wherein the partition wall includes a partition opening which makes the battery passing opening communicate with the entrance opening and has such a size that the battery passes through the partition opening and a lid that openably closes the partition opening. ### Claim 3 (depends on 1) The vehicle according to claim 1, wherein: the seat support frame further includes a reinforcing frame located so as to close part of the battery passing opening; and the reinforcing frame is detachably fixed to part of the seat support frame by a fastener. ### Claim 4 (depends on 1) The vehicle according to claim 1, further comprising a guide that guides the battery between the battery passing opening and a predetermined position in the under-seat space. ### Claim 5 (depends on 1) The vehicle according to claim 1, wherein: the battery includes an outer surface that is directed to an outside in the vehicle left-right direction, and in a vehicle plan view, inclined with respect to a vehicle center line extending in a vehicle front-rear direction; and the battery is located such that a virtual extension region defined by extending the outer surface in a direction perpendicular to the outer surface is located inside the entrance opening. ### Claim 6 (depends on 1) The vehicle according to claim 1, further comprising a battery case accommodating the battery, wherein the battery case includes a seat supporting portion that supports the seat. ### Claim 7 (depends on 1) The vehicle according to claim 1, wherein the battery is directed to the entrance opening. ### Claim 8 (depends on 1) The vehicle according to claim 1, wherein: the frame body further includes a rear post that is located behind the under-seat space and at a vehicle left-right direction outside portion of the floor frame and extends upward from the floor frame and a front post that is located at the vehicle left-right direction outside portion of the floor frame and in front of a foot space located in front of the seat support frame and extends upward from the floor frame; and an outer surface of the battery which is directed to an outside in the vehicle left-right direction and a vehicle front side is located between the front post and the rear post when viewed in a direction facing the outer surface. ### Claim 9 (depends on 8) The vehicle according to claim 8, wherein: the frame body includes a reinforcing frame that overlaps the outer surface of the battery when viewed in the direction facing the outer surface of the battery; and the reinforcing frame is detachably fixed to the floor frame. ### Claim 10 (depends on 8) The vehicle according to claim 8, wherein: the seat includes a rear seat; and the seat support frame includes a rear seat support frame that supports the rear seat from below, the vehicle further comprising a front seat located in front of the rear seat, wherein: the frame body further includes a front seat support frame that supports the front seat from below; and the foot space includes a rear foot space located between the front seat support frame and the rear seat support frame. ### Claim 11 (depends on 1) The vehicle according to claim 1, wherein: the frame body further includes a rear post that is located behind the under-seat space and at a vehicle left-right direction outside portion of the floor frame and extends upward from the floor frame and a front post that is located at the vehicle left-right direction outside portion of the floor frame and in front of a foot space located in front of the seat support frame and extends upward from the floor frame; and a virtual extension surface of a front surface of the battery and a virtual extension surface of a rear surface of the battery pass through a space between the front post and the rear post, the front surface and the rear surface extending obliquely with respect to the vehicle left-right direction.
