Abstract

A hydraulic torque converter with a lock-up clutch wherein the cross section of a torus formed by an impeller, turbine and a stator is determined to satisfy that the ratio of its axial length L to its radial height H (L/H) is 0.64-0.80, the ratio of its inner diameter D.sub.i to its outer diameter D.sub.o (D.sub.i /D.sub.o) is 0.40-0.33 and the ratio of an annular flow passage area a at the exit of the impeller to a circular area A defined by the torus outer diameter (a/A) is 0.18-0.23.
