PROBLEM TO BE SOLVED: To provide a method for easily and economically solving a problem on poor stability of a torsional damping device which includes elastic members of a plurality of groups in a state of being arranged in series through phase adjustment members so that the elastic members deform in phase with one another and are centered.SOLUTION: A torsional damping device includes first movable elements 13 and 14 and second movable elements 15 and 16 coaxially rotatable around an axis X, a center hub rotatably coupled to the second movable elements 15 and 16, at least one group of elastic members 25 and 26 actuating against relative rotation of the first movable elements 13 and 14 and the second movable elements 15 and 16, phase adjustment members 32 and 33 constituted of two parts 32 and 33 for arranging the elastic members in the group in series so that the elastic members of each group deform in phase with one another, and a pendulum damper 48 rotationally connected with the phase adjustment members 32 and 33, so that the phase adjustment members are centered on the center hub by means of the pendulum damper 48.SELECTED DRAWING: Figure 2 【課題】複数グループの弾性部材を含み、弾性部材が互いに位相変形するように位相調整部材を介して直列に配設され、センタリングされるため、安定性が低い。この課題を簡易で経済的な解決法を与えることを目的とする【解決手段】軸Ｘの周りを同軸で回転可能な第１可動要素１３、１４及び第２可動要素１５、１６と、第２可動要素１５、１６に回転可能に繋げられた中央ハブと、第１可動要素１３、１４と第２可動要素１５、１６の相対回転に抗して作用する、少なくとも１つのグループの弾性部材２５、２６と、２つの部分３２、３３によって形成され、各グループの弾性部材が互いに位相変形するように、グループ内の弾性部材を直列に配設する位相調整部材３２、３３と、位相調整部材３２、３３に回転可能に結合される振り子ダンパ４８であって、振り子ダンパ４８を介して位相調整部材が中央ハブにセンタリングされる。【選択図】図２
