PROBLEM TO BE SOLVED: To prevent a container having a relatively deep groove part extended in the circumferential direction at a close position to the bottom from being difficult to be taken out when the container is held. SOLUTION: This cup holder is provided with a small diameter support 3 having an arc-shaped small-diameter holding surface rotatably installed on a holder main body 1 to support a small-diameter container, and a middle-diameter support 4 having a middle-diameter holding surface along an outline form of a middle-diameter container. An interval between tips of both ends of the small-diameter support 3 to get in contact with the surface of the middle-diameter container when the middle-diameter container is inserted into a containing part is set to be less than the maximum diameter, and more than 40% of the maximum diameter of a lower part of the middle-diameter container. Interference clearance between the small diameter support 3 and the middle-diameter container is long enough to make the smaller-diameter support 3 easy to come off the groove part 60, thereby the middle-diameter container is prevented from being hard to be taken out.
