PURPOSE: A measuring device for toque and axial force to fasten a fuel supply pipe to a common rail is provided to reduce the fastening time and to improve stability of fastening. CONSTITUTION: A measuring device for toque and axial force to fasten a fuel supply pipe to a common rail comprises a torque wrench(110), a pressing rod(120) and a load cell(130). The torque wrench joints a fuel supply pipe(C) in a boss formed on top of the common rail. The fuel supply pipe is screwed in the boss through a fixing cap(B) in which the fuel supply pipe passes through. The torque wrench measures the torque generating when screwing. The pressing rod leaded inside the common rail and is located on bottom of fuel supply pipe. The pressing rod slides downwards from the fuel supply pipe when the fuel supply pipe is screwed. The load cell is located bottom of the pressing rod. The load cell measures tension delivered through the pressing rod.
