PROBLEM TO BE SOLVED: To firmly construct a reserve seedling tray of a riding rice transplanter. SOLUTION: The reserve seedling tray is switchable between a seedling box placing state to position a stationary reserve seedling tray 12d and mobile reserve seedling trays 12b, 12c one above the other, and a state to position the stationary reserve seedling tray 12d and the mobile reserve seedling trays 12b, 12c on the same plane to form a rail-formed transporting plane extending in one direction, by vertically rotating the mobile reserve seedling trays 12b, 12c. Drawable supporting frames 22a, 22b to support the lower faces of the mobile reserve seedling trays 12b, 12c rotated in vertical direction are placed under the stationary reserve seedling tray 12d in a state to be insertable and extractable in one direction. The supporting frames 22a, 22b are positioned within the frame of the mobile reserve seedling trays 12b, 12c in plane view in a state supporting the mobile reserve seedling trays 12b, 12c, and positioned within the frame of the stationary reserve seedling tray 12d in plane view in a housed state.
