Abstract
A floor conveyor has a conveyed object support base portion supported on a conveying traveling body via a columnar support member that penetrates, in a vertical direction, a slit formed in a floor surface along a traveling path of the conveying traveling body. An auxiliary floor surface mechanism which narrows the width of the slit has protruding members protruding from the side of the slit to the center of the slit, where each of the protruding members includes a plate-shaped portion along a perpendicularly vertical direction and is held and biased by an elastic force in a protruding posture in which the protruding member protrudes to the center of the slit. When the protruding member contacts the columnar support member, the protruding member moves in the movement direction of the columnar support member against elasticity so as to allow the passage of the columnar support member.
