PROBLEM TO BE SOLVED: To increase torsional rigidity of a torsional vibration reducing device including a long travel damper. SOLUTION: This device is provided with a pair of side plates 1, 2 as an input side rotary members, a center plate 3 as an output side rotary member, a pair of springs 5, 6 disposed in series along a circumferential direction between a plurality of first spring seats 7 formed on a pair of the side plates 1, 2 and between second spring seats 3a formed on the center plate 3, and an intermediate member 8 including intermediate spring seats 8b put between a pair of the side plates 1, 2 and between a pair of the springs 5, 6 and an annular part 8a disposed radial direction outside of the second spring seats 3a. First abutment parts 8c are formed at circumferential direction both sides of a base end part of the intermediate spring seat 8b. Second abutment parts 3c abutting on the first abutment parts 8c to interrupt compression of one of a pair of the springs 5, 6 are formed at both side of a tip part of the second spring seat 3a of the center plate 3.
