Beverage container storage device

A beverage container storage device comprising:

• a holder member provided with an opening into which a beverage container is capable of being inserted, the holder member being configured to hold the beverage container inserted from an outside to an inside of the opening;
• a plate-shaped flap supported by the holder member so as to be rotatable between an initial rotation position at which the flap blocks at least a part of the opening and a use rotation position at which an opening area of the opening is larger than that at the initial rotation position;
• and
• a drive mechanism having rotation shafts about which the flap rotates relative to the holder member and a biasing member configured to generate a biasing force for biasing the flap from the use rotation position side toward the initial rotation position side, the drive mechanism being configured to rotate the flap from the initial rotation position toward the use rotation position against a biasing force of the biasing member when a flap tip portion of the flap is pressed downward as the beverage container is inserted into the inside of the opening, wherein
• the flap has
• a first rotation flap portion supported by the holder member so as to be rotatable about a first rotation shaft that is one of the rotation shafts, and
• a second rotation flap portion supported by the first rotation flap portion so as to be rotatable about a second rotation shaft that is one of the rotation shafts and different from the first rotation shaft, the second rotation flap portion being formed protruding on a side farther from the first rotation shaft than a flap tip of the first rotation flap portion,
• the biasing member has
• a first biasing member configured to generate a biasing force for rotating the first rotation flap portion about the first rotation shaft relative to the holder member in a rotation direction approaching an orientation at the initial rotation position of the flap, and
• a second biasing member configured to generate a biasing force for rotating the second rotation flap portion about the second rotation shaft relative to the first rotation flap portion in the rotation direction approaching the orientation at the initial rotation position of the flap, and
• the drive mechanism rotates the first rotation flap portion in the same rotation direction as in insertion of the beverage container from the outside to the inside of the opening, against the biasing force of the first biasing member in an initial stage of removing the beverage container from the inside to the outside of the opening.
