A vane wheel for torque converter with a plurality of blades formed integrally with a shell in a casting process is disclosed. The blade tilts relative to an axial direction of the vane wheel and has an inner surface located on a positive pressure side thereof and an outer surface located on a negative pressure side thereof. A root thickness in a middle section between an outer periphery side and an inner periphery side of the shell is thicker than a root thickness on the inner periphery side relative to a blade cross section along a circumferential direction from an axis center of the vane wheel.
