The present invention more securely prevents or inhibits a shaft-support component from being damaged when a load exceeding a predetermined level is exerted on a rotary body. This shaft-support structure for a rotary body is provided with an inner side bearing portion (22) disposed to a base panel (20) and an inner side fulcrum shaft (45) that is disposed to a cup holder (40L) and is supported by the inner side bearing portion (22) in a rotatable manner. The inner side bearing portion (22) has slits (24s, 26s) on the side apart from the base panel (20). A center cover (80) is disposed at a position facing the slits. The cup holder (40L) is configured in such a way that, when a load exceeding a predetermined level is exerted in the direction away from the base panel (20), the inner side fulcrum shaft (45) moves in a direction in which the inner side fulcrum shaft (45) disengages from the inner side bearing portion (22) through the slits (24s, 26s) and, therewith, by pressing the center cover (80) from the inside and causing the center cover (80) to move in the direction separating from the inner side bearing portion (22), the inner side fulcrum shaft (45) disengages from the inner side bearing portion (22).
