PROBLEM TO BE SOLVED: To provide a method for manufacturing a lubricant application barrel which has less unevenness in applying a lubricant and is superior in slidability with a gasket.SOLUTION: This method includes: (A) a step of spraying a lubricant to the inner peripheral surface of a resin barrel and (B) a step of using an elastic member capable of being inserted and withdrawn into the resin barrel, and applying the lubricant so as to extend by allowing the lubricant to slide in a single direction from the front end side of the resin barrel to the base bottom side while adjusting the diameter size of the elastic member in the diameter direction of the barrel.COPYRIGHT: (C)2014,JPO&INPIT【課題】潤滑剤の塗布ムラが少なく、ガスケットとの摺動性に優れた潤滑剤塗布バレルを製造する。【解決手段】(イ)樹脂製バレルの内周面に潤滑剤を噴き付ける工程と、(ロ)その樹脂製バレル内に出し入れ可能である弾性部材を用いて、そのバレルの径方向におけるその弾性部材の直径サイズを調整しながら、その弾性部材をその樹脂製バレルの先端部側から基底部側に向けて一方向に摺動させて潤滑剤を塗り伸ばす工程と、を含む、潤滑剤塗布バレルの製造方法。【選択図】図2A
