A syringe assembly (1) has a hub body (15) which can be inserted into a hub insertion hole (4) and pulled out thereof into inside a syringe body. A chamfer portion (19b) is formed at the hub body, being capable of engaging with the hub insertion hole. A needle insertion hole (21) capable of being inserted a needle (36) therein is provided with an end face of the hub body in a direction of an axis center of the hub body. A flow hole (27) is provided with the hub body such that the needle insertion hole and an inside of the syringe body are communicated with each other in the direction of the axis center. A piston engagement hole (29) is provided on end face side of the hub body, so as to engage with the piston (40). A seal taper (17) is annularly formed at the hub body, such that its outside diameter is made narrower for the end face side, so as to abut on and contact with an inner face of the hub insertion hole. <IMAGE> |
