To provide a collapsible table having high practicability.

This collapsible table includes a leg locking mechanism 70 provided separately from a stay. The leg locking mechanism 70 includes a rocking member 72 in which the proximal end is journaled to a frame 20, the distal end located in a position near the base end of the leg 16 can be rocked by its dead load. (i) When the front of a top plate 12 points upward with the legs 16 put in the erect attitude, the rocking member 72 takes a first attitude (Fig.4(a)) in which the distal end thereof is located separate from the top plate 12 more than the proximal end, and in the first attitude, the leg 16 abuts on the distal end thereof to inhibit the leg 16 from tilting. (ii) When the back of the top plate 12 points upward in the erecting state of the legs, the rocking member 72 takes a second attitude (Fig.4(c)) in which the distal end thereof approaches the top plate 12 more than in the first attitude, and in the second attitude, it allows the leg 16 to tilt (Fig.4(d)).
