Patent ID: 10683908

Abstract:
A torque converter is provided in which abutment claw portions provided integrally with one of a pair of retaining plates of a dynamic damper mechanism are inserted into a cutout part, a spring retaining member fixed to a clutch piston having the cutout part, wherein the cutout part is formed so that an inner end of the cutout part along a radial direction of an output shaft is positioned further outside than an inside end of a damper spring in the radial direction, and the abutment claw portion is formed so that part of the abutment claw portion overlaps an inertia plate in a projection onto a plane passing through the abutment claw portion and an axis of the output shaft. Such arrangement shortens the axial distance between the clutch piston and the dynamic damper mechanism while maintaining function of the spring retaining member in retaining the damper spring.
