A folding table includes: a table body provided with a pair of hinge pins and a pair of lock pins, each of the pairs protruding oppositely in left-right direction; and a pair of left and right brackets having shaft holes in which the hinge pins are inserted and movable holes in which the lock pins are inserted. Spring members mounted in the movable holes press the lock pins. The table body is rotatably supported by the brackets affixed to a wall surface. The folding table has closing plates having through-holes respectively through which the hinge pins and the lock pins are penetrated. The closing plates are sandwiched between the table body and the brackets to close the movable holes.
