PROBLEM TO BE SOLVED: To provide a torsional damper capable of preventing an annular mass body 2 from coming out to a front side even when an elastic body 3 is broken, and being inexpensively manufactured. SOLUTION: This torsional damper is composed of a hub 1 mounted on a shaft end of a crank shaft of an engine, the annular mass body 2 coaxially mounted on an outer peripheral side of the hub 1 in a state of being relatively displaceable, and an elastic body 3 elastically connecting the hub 1 and the annular mass body 2. An outward stopper 14 bent to the outer peripheral side is mounted on an end part at the front side of a rim part 13 of the hub 1, and an inward stopper 22 bent to an inner peripheral side is mounted on an end part at a back side of the annular mass body 2. The hub 1 and the annular mass body 2 are molded as an integrated matter continued to each other by the outward stopper 14 and the inward stopper 22, and then separated from each other by cutting.
