CUP HOLDER

PROBLEM TO BE SOLVED: To provide a cup holder capable of holding stably objects of various sizes to be held.SOLUTION: A cup holder 1 has a bottomed cylindrical holder portion 2 formed with a holding space 5 holding an object to be held. The holder portion 2 includes a bottom wall 4 formed in the bottom of the holding space 5 and a cylindrical vertical wall 3 erected upward from the bottom wall 4 and surrounding the side part of the holding space. The vertical wall 3 has a smallest diameter part 30 with the smallest interval between mutually opposing parts, in the middle part 3c between the upper end part 3a and the lower end part 3b in the vertical direction. Between the smallest diameter part 30 and the lower end part 3b of the vertical wall 3, there is formed a first tapered part 31 in which the interval between mutually opposing parts increases from the smallest diameter part 30 toward the lower end part 3b. Between the smallest diameter part 30 and the upper end part 3a, there is formed a second tapered part 32 in which the interval between mutually opposing parts increases from the smallest diameter part 30 toward the upper end part 3a.
