Abstract:
A lift-driving engagement chain capable of improving buckling strength of a pair of lift-driving engagement chains, by modifying the buckling restricting flat surfaces in order to suppress the force which causes a relative slippage along buckling restricting flat surfaces between hooked inner tooth plates and outer tooth plates that contact each other through the buckling restricting flat surfaces.
