Abstract

Provided is a torque converter () which comprises: a casing () coupled to an output shaft of an engine; a torus (T) defined by a pump (), a turbine () and a stator () each disposed within the casing (); a multi-plate lockup clutch () adapted to directly couple the turbine () and the casing (); and a lockup damper () adapted to absorb shock during engagement of the lockup clutch (). The lockup clutch () and the lockup damper () are arranged within a space between the torus (T) and a surface of the casing () on the side of the engine, in an axially overlapping relation. The lockup clutch () is disposed on a radially inner side with respect to a widest region (T) of the torus (T), and the lockup damper () is disposed on a radially outer side with respect to the widest region (T). This makes it possible to engage the lockup clutch () with excellent response while suppressing shock, and shorten an overall length of an automatic transmission.
