PURPOSE: An auxiliary tool for assembling a flange of an exhaust pipe is provided to reduce working time for combining bolts, make a lower layout of a vehicle free, and improve operation efficiency by combining both bolts for combining both sides of the flange at the same time with equal combining torque. CONSTITUTION: An auxiliary tool(20) for assembling a flange of an exhaust pipe comprises a body(21), a driving socket(30), a pair of driven sockets(40), and a belt(50). The body includes a U-shape round unit(23) having a radius larger than the radius of the exhaust pipe in the center. The driving socket is rotatively shaft-combined to the lower part of the round unit as a separate tool and composed of a polygonal tool inserting hole(31) for inserting the tool into the inner peripheral surface and teeth(32) formed on the outer peripheral surface at regular intervals. The driven sockets are shaft-combined to both sides of the body with keeping a gap of bolts combined to the flange of the exhaust pipe and composed of a bolt inserting hole(41) penetrated in a bolt head-shape and formed in the inner peripheral surface and teeth arranged on the outer peripheral surface at regular intervals. The belt rotates the driving socket with the tool and the pair of driven sockets in same direction at the same time.
