A clutch outer ring member 1 of approximately s5 is made, and this clutch outer ring member 1 has a mounting hole 3 in the center to which the spline member 2 is attached, a peripheral wall portion 4 extending in the axial direction, and a peripheral wall portion 4 extending in the axial direction. A spline member second joint portion 5 is integrally formed around the attachment hole 3 and protrudes to the opposite side.

をし、このためスプライン部材２を自然に焼入れする。In this state, the clutch outer ring member 1 and the spline member 2 are joined together in a furnace by, for example, copper brazing. During this brazing, the steel material of the spline member 2 becomes austenite at a temperature above the eutectoid point and the A3 transformation point, and when this is cooled in the furnace as it is, it becomes a martensitic structure. The atmospheric gas 1 sealed in the brazing furnace contains hydrogen as a reducing agent, and this hydrogen acts as a paste during Cappani brazing.
' together with its thermal conductivity, it acts to effectively cool the spline member 2 during cooling in the furnace after copper brazing, thereby naturally quenching the spline member 2.
