• wherein the at least one inclination preventive member includes
• a main shaft extending in the first horizontal direction and rotatably and axially supported by the support,
• a pair of arms extending from opposite ends of the main shaft toward an identical side in a second horizontal direction crossing the first horizontal direction, and
