In a non-use state where no beverage container is housed in a housing space, holding claws are urged by a ring spring to an advanced reference position where the holding claws are mostly advanced into the housing space and a bottom plate is urged by a coil spring to a highest reference position where the bottom plate is mostly moved upwardly. When a beverage container is housed in the housing space, the holding claws are pushed toward the radial outer direction of the housing space by the side surface of the beverage container, whereby the holding claws move backwardly against the urging force of the ring spring. Simultaneously, since the weight of the beverage container is applied to the bottom plate, the bottom plate moves downwardly against the urging force of the coil spring, whereby a lock member moves downwardly together with the downward movement of the bottom plate. Thus, since a restricted slanted surface abuts against the lock member, the weight of the beverage container is transmitted to a restricted vertical surface from the lock member, so that the backward movement of the holding claw is restricted.
