PROBLEM TO BE SOLVED: To accurately join a rear end part of a tire constitution member to a tip part, after realizing an improvement in productivity, when molding an unvulcanized tire.SOLUTION: A tire manufacturing device 1 grips a rear end part of a tire constitution member G by both hands 30A and 30B, and puts the rear end part on a tip part so that the center of the rear end part is put on the tip part. When putting the rear end part of the tire constitution member G on the tip part, the tire manufacturing device 1 separates both ends of the rear end part put on the tip part of the tire constitution member G from the tip part while bringing the center of the rear end part into close contact with the tip part by both hands 30A and 30B. Both ends of the rear end part of the tire constitution member G are separated from the tip part. Next, the tire manufacturing device 1 butts and joins both ends of the member by pressing both ends of the rear end part of the tire constitution member G to the tip part. 【課題】未加硫タイヤを成形する際に、生産性の向上を実現した上で、タイヤ構成部材の後端部を先端部に精度良く接合する。【解決手段】タイヤ製造装置１は、両ハンド３０Ａ、３０Ｂによりタイヤ構成部材Ｇの後端部を把持し、後端部の中央が先端部に被さるように、後端部を先端部に被せる。タイヤ構成部材Ｇの後端部を先端部に被せると、タイヤ製造装置１は、両ハンド３０Ａ、３０Ｂにより、タイヤ構成部材Ｇの先端部に被せられた後端部の両端を、後端部の中央を先端部に密着させたまま先端部から引き離す。タイヤ構成部材Ｇの後端部の両端を先端部から引き離す。次に、タイヤ製造装置１は、タイヤ構成部材Ｇの後端部の両端を先端部に押し付けることにより、部材の両端を突き合わせて接合する。【選択図】図１
