Outer circumferential surfaces (33, 35) of opening-side end sections (30, 31) in a press-molded front cover (12) and pump shell (7) are machined such that the outer diameter dimensions thereof become the same. In a state in which the opening-side end sections are caused to protrude, a laser beam (R) or other high-energy beam is irradiated towards the protruding surfaces (30, 31) from the outer diameter direction, and same are welded. As a result, accurate welding using easy machining is performed, and high-precision fluid couplings that are easily post-processed can be produced. 本发明提供液力耦合器的制造方法以及液力耦合器。将通过冲压成形的前盖(12)以及泵外壳(7)的开口侧端部(30、31)的外周面(33、35)，以外径尺寸成为相同的方式进行除去加工。在使上述开口侧端部彼此对接的状态下，朝向该对接面(30、31)从外径方向照射激光束(R)等的高能光束进行焊接。由此，能够通过容易的加工正确地进行焊接，从而容易地制造后工序容易的高精度的液力耦合器。
