A cup holder includes a case main body defining a housing chamber; a lid member rotatably attached to the case main body between a closed position closing the opening portion and an open position opening the opening portion; a cup retaining member; and a parallel link mechanism connecting the case main body and the cup retaining member. A connecting mechanism connects the lid member and the cup retaining member so as to interconnect together so that the cup retaining member ascends to the ascent position from a descent position, and the cup retaining member descends from the ascent position to the descent position. Stopper abutting portions are provided in the cup retaining member and the lid member to control a downward movement of the cup retaining member.
