Abstract
A vibration damping device in which vibration damping performance of a damper having a chamber holding a rolling member is improved. The vibration damping device is adapted to damp vibrations resulting from a pulsation of torque applied to a rotary member by an oscillating motion of a rolling member connected with the rotary member while being allowed to rotate relatively therewith. The vibration damping device is provided with a casing member enclosing the rolling member, and a sealing member that connects the casing member with the rotary member in a manner such that the rotary member is allowed to rotate relatively with the casing member, while preventing oil from entering into an inner space of the casing member where the rolling member is held to oscillate.
Claims10
A vibration damping device, comprising:
- a rotary member to which torque is applied;
- a rolling member connected with the rotary member while being allowed to rotate relatively to the rotary member, the vibration damping device being configured to damp vibrations resulting from a pulsation of torque applied to the rotary member by an oscillating motion of the rolling member;
- a casing member enclosing the rolling member;
- a sealing member that has an elasticity and that is interposed between the casing member and the rotary member in a manner such that the rotary member is allowed to rotate relatively to the casing member, while preventing oil from entering into an inner space of the casing member where the rolling member is held;
- and
- an elastic member that reduces a phase shift between the rotary member and the casing member rotating relatively to each other.
