Torque transmission apparatus

A torque transmission apparatus for transmitting a torque from a first rotor rotating around an axial line to a second rotor, comprising:

• an intermediate member disposed in a power transmission path between the first rotor and second rotor;
• a first elastic member interposed between the first rotor and the intermediate member;
• a second elastic member interposed between the intermediate member and the second rotor;
• a third elastic member;
• an inertial body connected to the intermediate member through the third elastic member;
• and
• an elastic member supporter configured to support the third elastic member to be expandable and contractible,
• wherein the elastic member supporter supports the third elastic member in a manner of applying an initial load to the third elastic member, in an initial state of the first and second rotors being non-rotating.
