Abstract

The present invention relates to a pendulum damper of a vehicle torque converter, the pendulum damper being provided in the vehicle torque converter so as to dampen vibration and impact in the rotational direction of the torque converter and, more specifically, to a pendulum damper in which a pair of pendulums are coupled to a support plate and fixed by being joined together, and a vehicle torque converter including same.
