Zusammenfassung:	The present invention relates to a method for manufacturing a torque converter, which can prevent a decline in performance of a torque converter while preventing a loss of a fluid when the torque converter is operated by closing a slit provided in an impeller core in a process of coupling an impeller blade to the impeller core. According to an embodiment of the present invention, the method for manufacturing a torque converter having an impeller and a turbine comprises the following steps of: (a) forming a flange unit to extend at one side of a slit formed through a slit process in an impeller core or a turbine core; (b) inserting an insertion protrusion unit of a blade into the slit after the (a) step; and (c) caulking the flange unit to be fixated to the slit of the core after the (b) step. 본 개시는 임펠러 코어에 임펠러 블레이드를 결합하는 과정에서 임펠러 코어에 제공된 슬릿을 폐쇄하여 토크 컨버터가 작동할 때 유체의 손실을 막고 토크 컨버터의 성능저하를 방지할 수 있는 토크 컨버터의 제조방법에 관한 것이다. 본 개시의 실시예에 따른 토크 컨버터의 제조방법은 임펠러 및 터빈을 포함하는 토크 컨버터의 제조방법에 있어서, (a) 임펠러 코어 또는 터빈 코어에 슬릿 가공을 통해 형성된 슬릿의 일측에 플랜지부를 연장되게 형성하는 단계와, (b) 상기 (a)단계 후에 상기 슬릿에 블레이드의 끼움돌기부를 삽입하는 단계와, (c) 상기 (b)단계 후에 상기 코어의 슬릿에 상기 플랜지부가 고정되도록 코킹하는 단계를 포함한다.
