PROBLEM TO BE SOLVED: To provide a conveyor for raising seedling boxes structured so that a plurality of endless conveyor belts are placed in a direction orthogonal to a raising seedling box-conveying direction at prescribed intervals and are supported on conveyor frames to be freely driven and turnable, the raising seedling boxes are received by a plurality of endless conveyor belts from below to be conveyed, and thus the endless conveyor belts are inexpensively prevented from sagging and exert excellent durability. SOLUTION: The conveyor for raising seedling boxes is structured as follows: a supporting means 80 receiving and supporting the approaching sides of the endless conveyor belts 12, 24, 33 from below comprises a support axis 82 fixed to conveyor frames 11, 21, 32 along a direction orthogonal to the raising seedling box-conveying direction, and a cylinder 83 which is received by a plurality of endless conveyor belts 12, 24, 33 while being engaged with the support axis 82 from outside to be freely rotatable and supported on the support axis 82 to be freely rotatable; and the cylinder 83 is engaged with the support axis 82 from outside in the condition that the inner peripheral surface of the cylinder 83 comes in directly contact with the outer peripheral surface of the support axis 82.
