Abstract
A torque converter includes a pump shell constituting an internal space for retaining ATF and capable of rotating about the rotation axis; a blade engaging with the pump shell; and an extension sleeve pressing the blade against the pump shell. The pump shell has a groove into which a tip portion of the blade is fit formed at its inner peripheral surface. In the state where the tip portion is fit into the groove, the extension sleeve presses the blade to fix the blade to the pump shell. The groove forms an acute angle θ with respect to a meridian of the shell passing through the groove. The groove extends in one direction, has one end opened and the other end closed, and has a width larger on the side of the one end than on the side of the other end. The groove has a portion smallest in width equal to the width of the tip portion.
