A tire conveyor includes a roller portion provided at a position, in the width direction perpendicular to the conveying direction, without a conveying surface. The roller portion extends parallel to the conveying surface and is provided with a plurality of placement rollers forming a placement surface on which the tire is rotatably placed. An elevation mechanism includes a single actuator and a link mechanism connecting the roller portion or the conveyor to the actuator in a supported state and moves the placement surface of the roller portion upward and downward relative to the conveying surface by driving the actuator.
