PROBLEM TO BE SOLVED: To realize a drug feeder capable of efficiently delivering even a drug that easily rolls by improving an annular rotating body while following a double rotation type drug feeder. SOLUTION: An outer ring-shaped rotary body 200 axially rotates about a vertical line, an inner tilted rotary body 300 axially rotates about a tilted line, and the rotation of the ring-shaped rotary body 200 from above the tilted rotary body 300. In the medicine feeder 100 including the sorting mechanism 600 and the regulating mechanism 700 for aligning the solid medicines carried on the upper end peripheral portion 230, the diamond-shaped or spindle-shaped grooves 231 arranged in the circumferential direction are formed in the upper end peripheral edge of the annular rotating body 200. It is formed in the part 230. Further, a chamfer 232 is formed on the outer peripheral portion of the upper end peripheral portion 230, and the groove 231 is provided there. Further, the annular rotating body 200 is slightly tilted in such a direction as to raise the portion near the drop discharge port 14. The inclination β is smaller than the chamfer angle α.
