PROBLEM TO BE SOLVED: To provide a direct sowing apparatus configured to prevent jamming.SOLUTION: A direct sowing apparatus comprises an endless annular delivery belt 90. The delivery belt 90 is subjected to circulation driving along a predetermined circulation track. The delivery belt 90 has along the longitudinal direction thereof a plurality of feeding holes 84 obtained by opening the outside of the circulation track. In each of the feeding holes 84, an upstream-side inner wall surface and a downstream-side inner wall surface in a circulation direction of the delivery belt 90 are respectively inclined so as to expand outward. The upstream-side inner wall surface and the downstream-side inner wall surface are different in inclination mode. |
