To provide a manufacturing method of a power transmission shaft which can form a pipe body by winding fiber-reinforced plastic around a mandrel without receiving a constriction on a shape of the pipe body so much.SOLUTION: A manufacturing method of a power transmission shaft having a fiber-reinforced plastic pipe body 2, a stub yoke 3 connected to an end part of the pipe body 2, and formed with a through-hole 8 penetrating in an axial line O1 direction, and a stub shaft 4 comprises: a connecting process for connecting the stub yoke 3 and the stub shaft 4 to a mandrel 30 in which a sand mold 20 is formed; a winding process for forming the pipe body 2 by winding fiber-reinforced plastic to the sand mold 20, the stub yoke 3 and the stub shaft 4; a hardening process for hardening the pipe body 2; an external energy impartment process for collapsing the sand mold 20; a withdrawal process for withdrawing the mandrel 30 from the sand mold 20 and the through-hole 8 of the stub yoke 3; and a discharge process for discharging the collapsed sand mold 20 from the through-hole 8 of the stub yoke 3 which is opened by withdrawing the mandrel 30.SELECTED DRAWING: Figure 5

    【課題】管体の形状の制約をさほど受けずに、繊維強化プラスチックをマンドレルに巻き付けて管体を形成できる動力伝達軸の製造方法を提供する。【解決手段】繊維強化プラスチック製の管体2と、管体2の端部に接続し、軸線O1方向に貫通する通し孔8が形成されたスタブヨーク3、スタブシャフト4と、を備える動力伝達軸の製造方法であって、砂型20が形成されたマンドレル30にスタブヨーク3、スタブシャフト4を接続する接続工程と、繊維強化プラスチックを砂型20およびスタブヨーク3、スタブシャフト4に巻き付けて管体2を形成する巻付工程と、管体2を硬化する硬化工程と、砂型20を分解する外的エネルギー付与工程と、マンドレル30を砂型20およびスタブヨーク3の通し孔8から引き抜く引抜工程と、マンドレル30を引き抜くことで開いたスタブヨーク3の通し孔8から、崩れた砂型20を排出する排出工程と、を備える。【選択図】図5
