Zusammenfassung:	PROBLEM TO BE SOLVED: To surely bring tire constitution members wound around the outer peripheral surface of a molding drum into close contact with each other.SOLUTION: A tire molding press roll 10 includes a plurality of pressing bodies 1 arranged along the axial direction of a support shaft 11 and supported by the support shaft 11. The pressing body includes: an abutment part abutting against the surface of a tire constituting member 21 wound around the outer circumference of a molding drum 20; a journal part 1b arranged inside the abutment part and journaled by the support shaft; and a connection part connecting the abutment part and the journal part together and formed in an elastically deformable manner. 【課題】成型ドラムの外周に巻き付けたタイヤ構成部材同士を確実に密着させること。【解決手段】タイヤ成型用押圧ロール１０は、支持軸１１に軸方向に沿って配列されて支持される複数の押圧体１を備えており、押圧体は、成型ドラム２０の外周面に巻き付けられたタイヤ構成部材２１の表面に当接する当接部と、当接部の内側に配置されるとともに支持軸に軸支される軸支部１ｂと、当接部と軸支部との間を連結するとともに、弾性変形可能に形成された連結部とを備えている。【選択図】図７
