A key operation mechanism includes a key cylinder; a locking lever that extends from a side surface of the key cylinder; and an unlocking lever that extends from a side surface of the key cylinder in a direction that is different from the direction in which the locking lever extends. The key operation mechanism further includes a locking pull line that is configured to lock a door and an unlocking pull line that is configured to unlock the door. One end of the locking pull line is attached to the locking lever, and one end of the unlocking pull line is attached to the unlocking lever. When the key cylinder rotates in a locking direction, the locking lever pulls the locking pull line, and, when the key cylinder rotates in an unlocking direction that is opposite the locking direction, the unlocking lever pulls the unlocking pull line.
