The hatch door is for use on a track-laying vehicle. The door is urged open by rise of a wound torsion bar. The bar is anchored at one end to the vehicle hull, while the other end is attached to a casing which encompasses the torsion bar. The hatch door engages this casing in such manner that as the hatch is rotated from open to closed position the torsion bar is wound through the casing. The hatch is maintained in closed position by a latching lever. When this lever is actuated to release, the door springs open to its original position.
