A lean vehicle comprising: a driving preventing device configured to switch between a driving enabled state in which normal driving of the vehicle is being enabled and a driving disabled state in which the normal driving of the vehicle is being disabled; a stand including an end portion and configured to swing between a landed state in which the end portion is in contact with a ground surface and a flip-up state and, in the landed state, make the vehicle stand by itself while the vehicle is in a stop state; and an operation piece that is movable between a driving enabled position and a driving disabled position and sets the driving preventing device to the driving enabled state when the operation piece is at the driving enabled position and sets the driving preventing device to the driving disabled state when the operation piece is at the driving disabled position, wherein: when the stand is in the landed state, the operation piece is allowed to move between the driving enabled position and the driving disabled position, thereby allowing the driving preventing device to be switched between the driving enabled state and the driving disabled state; and when the stand is in the flip-up state, the operation piece interferes with the stand to be maintained at the driving enabled position, thereby maintaining the driving preventing device in the driving enabled state, characterized in that, when the operation piece is at the driving disabled position, the operation piece interferes with the stand in such a way that the operation piece serves as a stopper which blocks the movement of the stand, thereby preventing the stand from becoming the flip-up state. a driving preventing device configured to switch between a driving enabled state in which normal driving of the vehicle is being enabled and a driving disabled state in which the normal driving of the vehicle is being disabled; a stand including an end portion and configured to swing between a landed state in which the end portion is in contact with a ground surface and a flip-up state and, in the landed state, make the vehicle stand by itself while the vehicle is in a stop state; and an operation piece that is movable between a driving enabled position and a driving disabled position and sets the driving preventing device to the driving enabled state when the operation piece is at the driving enabled position and sets the driving preventing device to the driving disabled state when the operation piece is at the driving disabled position, wherein: when the stand is in the landed state, the operation piece is allowed to move between the driving enabled position and the driving disabled position, thereby allowing the driving preventing device to be switched between the driving enabled state and the driving disabled state; and when the stand is in the flip-up state, the operation piece interferes with the stand to be maintained at the driving enabled position, thereby maintaining the driving preventing device in the driving enabled state, characterized in that, when the operation piece is at the driving disabled position, the operation piece interferes with the stand in such a way that the operation piece serves as a stopper which blocks the movement of the stand, thereby preventing the stand from becoming the flip-up state. when the stand is in the landed state, the operation piece is allowed to move between the driving enabled position and the driving disabled position, thereby allowing the driving preventing device to be switched between the driving enabled state and the driving disabled state; and when the stand is in the flip-up state, the operation piece interferes with the stand to be maintained at the driving enabled position, thereby maintaining the driving preventing device in the driving enabled state, characterized in that, when the operation piece is at the driving disabled position, the operation piece interferes with the stand in such a way that the operation piece serves as a stopper which blocks the movement of the stand, thereby preventing the stand from becoming the flip-up state.
