PROBLEM TO BE SOLVED: To increase durability of a turbine runner by stably mounting blades at regular intervals between a shell and a core constituting the turbine runner of a torque converter, not causing the blades to rattle. SOLUTION: Slit holes 4 are bored through a shell 2 and a core 3, and a blade 1 has a bow shape with its outer face and its inner face each fitting to a curved shell inner peripheral face 7 and a curved core inner peripheral face 8 for abutment and being formed with tabs 5, each having a small protrusion 6. The tabs 5 are inserted into respective slit holes 4 of the shell 2 and the core 3, respectively, bent and crimped so as to allow the protrusions 6 to bite into the shell 2 and the core 3.
