TECHNICAL FIELD The present invention relates to a method of assembling and assembling an assembly for a syringe (10). In the method of assembling the syringe assembly (10) according to the present invention, the puncture needle (14) and the tube tip (18) of the outer tube (12) are inserted into the receiving hole (34) of the cap (16) A closed space forming step of forming a closed space (62) between the housing hole (34) and the pipe tip (18) before the tip of the hole (14) is pierced into the bottom wall (36) of the housing hole (34) An evacuation step of evacuating the interior of the closed space (62) via a needle hole (32) and an in-cylinder space (20) formed in the outer cylinder (12) and communicating with the needle hole (32) And a sealing step of further inserting the tube tip (18) into the needle hole (34) and inserting the tip of the puncture needle (14) into the bottom wall (36) to seal the tip of the needle hole (32).本発明は、シリンジ用組立体(10)の組立方法及び組立装置に関する。本発明に係るシリンジ用組立体(10)の組立方法は、キャップ(16)の収容孔(34)に穿刺針(14)及び外筒(12)の筒先(18)を挿入し、穿刺針(14)の先端が収容孔(34)の底壁(36)に刺し込まれる前に、収容孔(34)と筒先(18)との間に閉空間(62)を形成する閉空間形成工程と、針孔(32)と、外筒(12)に形成されて針孔(32)に連通する筒内空間(20)とを介して閉空間(62)内を排気する排気工程と、収容孔(34)に筒先(18)をさらに挿入して、穿刺針(14)の先端を底壁(36)に刺し込むことで針孔(32)の先端を封止する封止工程とを有する。
