Claim 1:
2. The manufacturing method for the joined body according to claim 1, wherein
the projecting portion includes;
a cylindrical outer peripheral surface having a uniform outer diameter along the rotation axis; and
an inclined outer peripheral surface provided on a tip end side of the projecting portion than the cylindrical outer peripheral surface, the inclined outer peripheral surface being to be joined to the inclined inner peripheral surface of the hollow portion by the flowing material, and the inclined outer peripheral surface having an outer diameter that decreases as the distance from the flange portion along the rotation axis increases,

the first member further includes a cylindrical inner peripheral surface connected to the end surface of the first member, the cylindrical inner peripheral surface having a uniform inner diameter along the rotation axis, and
in the first joining step, the inclined outer peripheral surface of the projecting portion is accommodated inside the inclined inner peripheral surface of the hollow portion, and a root side clearance formed between the cylindrical inner peripheral surface of the hollow portion and the cylindrical outer peripheral surface of the projecting portion is smaller than a tip end side clearance formed between the inclined inner peripheral surface of the hollow portion and the inclined outer peripheral surface of the projecting portion.
