CUP HOLDER

A cup holder includes a tray portion configured to be vertically movable, and a lock mechanism. The lock mechanism includes a linkage member, an urging member, an intermediate member, and an engagement portion. The linkage member moves in a first direction when the tray portion is lowered, and moves in a second direction when the tray portion is raised. The urging member urges the linkage member in the second direction. The intermediate member moves between a first position and a second position. When the intermediate member is located at the second position, the engagement portion restricts movement of the linkage member in the second direction to lock the tray portion against upward movement. When the intermediate member is located at the first position, the engagement portion allows movement of the linkage member in the second direction to unlock the tray portion, thereby allowing the tray portion to move upward.
