A cup holder for a vehicle includes a holder body, an arm rotatable about a rotation center relative to the holder body in an opening direction and a closing direction, and a positioning mechanism for positioning said arm in at least one rotational position. The positioning mechanism includes a convex tooth and at least one concave portion. The convex tooth includes a first surface facing toward the opening direction of the cup holder, and a second surface facing toward the closing direction of the cup holder. An inclination angle of the first surface and an inclination angle of the second surface are different from each other in magnitude.
