Document Type and Number:
Japanese Patent JP2019138336
Kind Code:
A
Abstract:
To provide a torsional vibration reduction device of a power transmission device for a vehicle which can suppress the generation of the wear of a member for use in the torsional vibration reduction device.SOLUTION: In a torsional vibration reduction device 20 of a power transmission device 100 for a vehicle, each of rolling chambers 58 has a prescribed radial dimension D3 in a radial direction of a rotation center line C1, and each of rolling bodies 46 has: a first rolling body shaft part 48a penetrating the rolling chamber 58 in an axial line C2 direction; a first flange part 46b which is formed at one end part of the first rolling body shaft part 48a with an outside diameter D4 larger than a prescribed radial dimension D3; and a second flange part 46c which is formed at the other end part with an outside diameter D4 larger than the prescribed radial dimension D3. Both-end regions 90b of an inner wall face 90 of the rolling chamber 58 in the axial line C2 direction are formed into crowning shapes which retreat to the outside of the axial line C2 in the radial direction, and both-end regions 80b of a rolling face 80 of the rolling chamber 46 in the axial line C2 direction are formed into round shapes.SELECTED DRAWING: Figure 4
