Abstract
In a torque converter of a coreless type allowing and utilizing a fluid flow in a central core region, the impeller blade exit angle is made smaller in the central core region than in an outer region surrounding the core region so as to increase the velocity and amount of the fluid flow circulating in the outer region and participating in torque multiplication, and decrease the velocity and amount of the fluid flow circulating in the core region like the fluid flow in a fluid coupling.
