PROBLEM TO BE SOLVED: To provide a workbench allowing a worker to easily discharge foreign matters such as sediment mingled in the fitting portions of lock pins, if any, to the outside and also to easily confirm the operation position of the lock pins and the operation and damage state of the lock pins. SOLUTION: Leg bodies 2, which can be opened or closed between a folded position where they are folded nearly in parallel with the lower face of a top plate and an opened position where they are opened at the required angle against the lower face of the top plate, are fitted to both end sections of the top plate 1 via rotary connecting metal fixtures 3. A fixed side connecting plate 11 fixed to the top plate side and a moving side connecting plate 12 fixed to the leg body side are rotatably connected together by a pivotal spindle 10 to form each rotary connecting metal fixture 3. The leg bodies 2 are fixed at the folded position and the opened position by the lock pins 13 in this workbench, and the lock pins 13 are arranged near the upper end sections of the leg bodies 2.
