PROBLEM TO BE SOLVED: To provide a cup holder for a vehicle, which can smoothly rotate a cup receptacle in such a way as interlocking with putting-in and taking-out of a slide frame. SOLUTION: Guide members 41 and 42 are installed at a case 10 of a cup holder H for a vehicle, and a member to be guided 43 is set on a cup receptacle 32. When a slide frame 20 is drawn out, a twisted part 43a of the member 43 abuts on the guide member 42 to cause the cup receptacle 32 to rotate until it takes the horizontal attitude. When the slide frame 20 is pushed into the case 10, the twisted part 43a is guided by the guide member 41, and the cup receptacle 32 takes a plumb attitude.
