PROBLEM TO BE SOLVED: To always and accurately advance a nursery box lining up machine through a prescribed length and stop the nursery box lining up machine on longitudinal rails on which wheels of the nursery box lining up machine are rolled to advance the nursery box lining up machine. SOLUTION: This apparatus (a) is composed by installing a fixed stand device (b) lifting and lowering the rear of a nursery box lining up machine at the rear thereof, placing a positioning plate 7 having an elastic plate 13 attached to the rear thereof on longitudinal rails 2 under the nursery box lining up machine so as to be movable to the front and rear, connecting a forward positioning operating lever 25 attached to the nursery box lining up machine to the positioning plate 7 with the elastic plate 13 so as to advance the positioning plate 7 with the elastic plate 13 on the longitudinal rails 2 through a prescribed length by operation of the forward positioning operating lever 25 with an interlocking mechanism so that the rear wheels of the nursery box lining up machine ride on the elastic plate 13 of the positioning plate 7 with the elastic plate 13 to touch the positioning plate 7 with the elastic plate 13 and stop the advance of the nursery box lining up machine in the nursery box lining up machine capable of intermittently rolling wheels on the longitudinal rails 2 in the front and rear directions laid in a greenhouse, advancing and regularly arranging many nursery boxes after seeding.
