To provide a method for manufacturing a tube body used for a power transmission shaft capable of preventing slide of a filament at a mold-inclined portion of a mandrel and winding the filament to high density when winding the filament around the mold-inclined portion.SOLUTION: There is provided a method for manufacturing a tube body made of fiber reinforced plastic and having an inclined portion used for a power transmission shaft, by a filament winding method, which comprises an annular member attaching step for attaching an annular member 10 with a plurality of protrusions 11 provided at intervals in the circumferential direction, on a mold-inclined portion 9 of a mandrel 8 corresponding to the inclined portion or the outer peripheral surface of the mandrel 8 of a location through which the filament that winds around the mold-inclined portion 9 passes, a winding step of winding the filament so as to pass through between the protrusions 11, a hardening step of hardening the tube body, and a detaching step of pulling out the mandrel 8 from the tube body.SELECTED DRAWING: Figure 3

    【課題】フィラメントをマンドレルの型傾斜部に巻く際に、型傾斜部でのフィラメントの滑りを防止し、フィラメントを密に巻くことができる動力伝達軸に用いられる管体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で傾斜部を有する管体をフィラメントワインディング法により製造する動力伝達軸に用いられる管体の製造方法であって、前記傾斜部に対応するマンドレル8の型傾斜部9または型傾斜部9に巻き付くフィラメントが通る箇所のマンドレル8の外周面に、複数の突起体11が周方向に間隔を空けて設けられた環状部材10を取り付ける環状部材取付工程と、フィラメントを突起体11同士の間を通すように巻き付ける巻付工程と、管体を硬化させる硬化工程と、マンドレル8を管体から引き抜く脱芯工程と、を備える。【選択図】図3
