<P>PROBLEM TO BE SOLVED: To provide a torsional vibration reduction device which facilitates installation of an inertial mass body, and can suppress the generation of noise caused by the inertial mass body colliding with an inner wall surface of a rolling chamber. <P>SOLUTION: A phase is shifted between a cylindrical part 4 and a backlash reduction part 9, and thereby a gap is defined where a large diameter part 5b (5c) constituting the inertial mass body 5 can pass through, between a plurality of rolling surfaces 6 and 6 formed on an inner peripheral surface of the cylindrical part 4 and the backlash reduction part 9. After the large diameter part 5b (5c) passes through the gap, the phase between the cylindrical part 4 and the backlash reduction part 9 is matched to arrange the inertial mass body 5 so that a gap between the rolling surface 6 and a protrusion 10 formed on the backlash reduction part 9 becomes a predetermined gap. <P>COPYRIGHT: (C)2013,JPO&INPIT |
