Abstract
A torque converter is formed such that a flatness (2L/H) and a torus inside and outside radius ratio (r/R) satisfy equations; (1) 0.55<(2L/H)<0.75 and (2) 35<(r/R)<0.40. Then, assuming that an axially central position of the flow path along a rotational shaft of the torque converter is an origin, an axial direction is an X
direction and a radial direction is a Y direction, the configuration of the flow path of the turbine member is set such that the position of a point of contact between a straight line inclined 45 degrees relative to the X
direction and a curve constituting an external circumferential surface of the flow path in the turbine member is located within an area surrounded by two straight lines expressed as (3) Y=(R/L)xX+(6/4)xR and (4) Y=(R/L)xX+(7/4)xR.
