To give a function as a partitioning member for a second recessed part to a support member, which supports a small diameter drink container, in the case of supporting a large diameter drink container by forming an opening part of the second recessed part with a support part to be held so as to partition an opening of the opening part at need.

A device is provided with first recessed parts 12, which are arranged in the front and aft direction so that a large diameter drink container can be supported at a peripheral surface thereof, and a second recessed part 14, which is provided with an opening part 13 larger than the first recessed part 12 and which is formed so that the opening part 13 is freely opened and closed by a lid 5. A support member 15, which can be housed in the second recessed part 14, is supported by a step part 16 of the first recessed part 12 so that a small diameter drink container can be supported at the peripheral surface thereof. When the support member 15 is removed so that the first recessed part is exposed, a large diameter drink container can be supported by the first recessed part 12 at the periphery of the large diameter drink container.
