Kind Code:

A1

Abstract:

Disclosed is a syringe provided with an injection needle which has a storage function, the syringe having high assembling workability and productivity. A syringe (1B) comprises a syringe main body (1C) which comprises a plunger (32) operated to inject a liquid medicine; a cylindrical-shaped needle cover (11B) which accommodates an injection needle (100A); and a spring (18) which is held by the needle cover (11B) in a compressed state. The needle cover (11B) comprises a pair of seats (153A, 155A) coming into contact with respective both ends of the spring (18) for position regulation, and is configured to cause deformation to the seat (155A) to release the regulation on the spring (18) when the plunger (32) is further pushed after injection. After the release of the regulation, the spring (18) comes into contact with the syringe main body (1C), and thereby urges the needle cover (11B) to move the needle cover (11B) to a position where the injection needle (100A) is accommodated.
