<p>An object supporting device comprising an adjuster (6) for supporting a folding table (1) in a braking state by bringing a supporting end (6a) into abutment with a floor surface (F), a caster (7) movable from a retracted position (A) where a supporting end (7a) can come into abutment with the floor surface (F) at the same time as the supporting end (6a) of the adjuster (6) to a projecting position (B) where the supporting end protrudes beyond the supporting end (6a) of the adjuster (6) in the floor surface (F) direction, and a biasing mechanism (80) for biasing the caster (7) toward the floor surface (F) with a force greater than a gravity acting on the folding table (1) at the projecting position (B) and in the vicinity thereof, while biasing the caster toward the floor surface (F) with a force smaller than the gravity acting on the folding table (1) at the retracted position (A) and in the vicinity thereof.</p> |
