Claims

[Scope of utility model registration request]

An annular impeller shell having a generally arc-shaped cross section, a number of sheet metal impeller blades fixed at intervals in the circumferential direction on the concave inner surface of the impeller shell, and protrusions of the impeller blades on the concave inner surface of the impeller shell. In the impeller of the torque converter, the impeller is provided with a fitting slot, and the slot is formed so as to be recessed in the same direction as the output shaft when assembled, and the inner surface of the slot intersecting the circumferential direction of the impeller shell goes toward the bottom surface of the slot. An impeller for a torque converter, characterized in that the impeller is formed into a tapered shape that becomes narrower as the width increases, the tip of the protrusion of the blade is press-fitted into a portion of the inner surface near the bottom surface, and the blade is brazed to an impeller shell.
