PROBLEM TO BE SOLVED: To provide a delivering device for granular preparations, capable of mechanizing works for fertilizing and administering medication, performing fertilizing and administering the medication to seedling-growing boxes easily, and changing the fertilizer/medication mixing ratios easily and improving the working capacity in fertilizing and administering the medication. SOLUTION: This delivering box for granular preparations is provided by installing a sideways shaft delivery roll 10 installed with multiple side groove- shaped delivery recessed parts 11 as annexed by taking a prescribed distance in parallel in a direction of the generating line on an outer peripheral surface by a sideways shaft rotation at the upper position of a conveying stand 1 for conveying the seedling-growing boxes 2, a delivery hopper 6 facing to the side surface in the rotationally elevating side of the sideways shaft delivery roll 10, a rotary brush 15 rotating in reverse direction in a contact surface provided on the upper surface side of the sideways shaft delivery roll 10, and a guide 16 for guiding the granular preparations 4 falling down from the delivery recessed part 11 of the sideways shaft-delivery roll 10 by passing through the lower side of the rotary brush 15 to the lower seedling-growing boxes 2.
