Abstract
A syringe (B) comprises: a syringe body (C) including a plunger () to be operated for injection of a drug solution; a cylindrical needle cover (B) housing an injection needle (A); and a spring () held in a compressed state by the needle cover (B). The needle cover (B) has seats (A) and (B) in a pair that abut on corresponding opposite ends of the spring () to restrict the position of the spring (). Pushing in the plunger () further after injection deforms the seat (A) to release restriction on the spring (). The spring () free from the restriction abuts on the syringe body (C). This biases the needle cover (B) to move the needle cover (B) to a position where the injection needle (A) is housed.
