Zusammenfassung:	To provide a manufacturing apparatus for barrel split body that can suppress bulging at welding points.SOLUTION: A manufacturing apparatus 1 has a mandrel 20 and a welding block 40. An outer circumferential surface 21 of the mandrel 20 is a holding surface that holds a sheet member 70 so that it becomes cylindrical. The welding block 40 welds two ends 71, 72 of the sheet member 70 along an axial direction of the mandrel 20 by heating and pressurizing them from outer peripheral side.SELECTED DRAWING: Figure 6 【課題】溶着箇所の膨らみを抑制し得る胴部分割体の製造装置を提供する。【解決手段】製造装置１は、マンドレル２０と、溶着ブロック４０と、を備えている。マンドレル２０の外周面２１は、シート部材７０を筒状になるように保持する保持面となっている。溶着ブロック４０は、マンドレル２０の軸方向に沿うシート部材７０の両端部７１，７２を外周側から加熱および加圧することで溶着する。【選択図】図６
