PROBLEM TO BE SOLVED: To provide an ice drink dispenser, having improved supply efficiency of ice to an auger.SOLUTION: A partition plate 11 includes: a curved part 11a having a cross-section of a shape concentric to the circular locus C drawn when each of blades 23a to 23c is rotated; and an inclined inclination part 11b that is connected to the end part 11a1 of the auger 15 side of the curved part 11a and has a fixed gradient. The end part of the auger 15 side of the inclined part 11b is connected to the end part of a circular-arcuate bottom part 18 that stores the auger 15 to form a connection part 19. The curved part 11a is terminated at the end part 11a1 actually, however, when a virtual curved part 11a' (broken line part) elongated from the end part 11a1 with a curvature radius equal to the curvature radius of the curved part 11a is supposed, the gradient of the inclination part 11b is more moderate than the gradient of a tangential line T (chain line) of the virtual curved part 11a' on the connection part 19.
