PROBLEM TO BE SOLVED: To provide a torque converter with a ring gear, which reduces the number of welding points of a torque converter shell and restrains production cost. SOLUTION: In the torque converter with the ring gear, which transmits motive power from an engine to an automatic transmission, a torque converter shell 10 is formed by welding Wa the external peripheral end 14 of a torque converter cover 11 and the external peripheral end 18 of an impeller cover 15 to each other along the peripheral direction, and the ring gear 23, which continues in the peripheral direction in the external peripheral face of the rim section 20 of the impeller cover 15 projected from the welding section Wa, is formed integrally by plastic working.
