PROBLEM TO BE SOLVED: To provide a method of manufacturing a syringe with a needle, with which a needle tube and the syringe can be integrally formed by insert molding and the needle tube can be accurately positioned.SOLUTION: The method of manufacturing a syringe with a needle includes following steps of: supporting a proximal end part of a needle tube 3 by a support member installing the needle tube 3 and the support member to a cavity space of a die for forming the syringe holding the needle tube 3 by a pair of chuck members 23 and injecting a resin into the cavity space of the die and molding the syringe. A groove part 23b provided on the pair of chuck members 23 has two contact surfaces 23c which are in contact with the needle tube 3 and are inclined in the direction of getting closer to each other as separated from the opening of the groove part 23b.COPYRIGHT: (C)2013,JPO&INPIT【課題】インサート成形によって針管とシリンジを一体に形成することができると共に針管の位置決めを正確に行うことができる針付きシリンジの製造方法の提供。【解決手段】針付きシリンジの製造方法は、以下に示す工程を含む。針管3の基端部を支持部材で支持する工程。シリンジを形成する金型のキャビティ空間に針管3及び支持部材を設置する工程。針管3を一対のチャック部材23によって把持する工程。金型のキャビティ空間内に樹脂を注入し、シリンジを成形する工程。一対のチャック部材23に設けられた溝部23bは、針管3に接触すると共に溝部23bの開口から離れるにつれて互いに近づく方向に傾斜した2つの接触面23cを有する。【選択図】図8
