PROBLEM TO BE SOLVED: To provide a highly reliable torsional damper manufacturable at rather low cost. SOLUTION: This torsional damper comprises a disk damper body 11, first and second annular elastic members 12 and 13 fixed to both faces of the damper body, inertia rings 14 and 16 fixed to the first and second annular members so as to hold the damper body through clearances thereof from the peripheral edge part of the damper body, and a connection ring 17 connecting the peripheral edge part of the first inertia ring to the peripheral edge part of the second inertia ring through the clearance thereof from the peripheral edge of the damper body. The outer diameter of the first inertia ring and the outer diameter of the second inertia ring are formed larger than the outer diameter of the damper body, a projected line 17a allowed to be inserted between the opposed peripheral edge parts of the first and second inertia rings is formed on the entire inner peripheral surface of the connection ring, and annular wedge members 18 and 30 are press-fitted between the outer peripheral surfaces of the first and second inertia rings and the inner peripheral surface of the connection ring so that the projected line can be held by the first and second inertia rings.
