Zusammenfassung:A torque converter 1 is a device for transmitting torque by fluid, and includes a front cover 14 , an impeller 18 , a turbine 19 , and a stator 20 . The impeller 18 , the turbine 19 and the stator 20 constitute a fluid operating chamber 6 having a torus shape. Flattening (L/D 1 ) is less than or equal to 0.18, wherein D 1 is an outer diameter of the fluid operating chamber 6 and L is the axial direction length of the fluid operating chamber 6 . In the impeller shell 22 , a surface 22 a on which the impeller blades 23 are fixed has an impeller straight portion 22 b showing a straight line in a cross section. In the turbine shell 25 , a surface 25 a on which the turbine blades 26 are fixed has a turbine straight portion 25 b showing a straight line in a cross section.
