PROBLEM TO BE SOLVED: To provide an injector in which an injection object material leaked during injection, and a combustion residue of an explosive component used as a driving source do not have a sanitary impact.SOLUTION: An injector includes a syringe unit having a syringe into which an injection object material is injected, an igniter, and a piston, and a starting unit for starting the syringe unit. The syringe unit includes a cylindrical housing incorporating the igniter and the piston, and is configured so that the syringe can be mounted in a housing space formed in the housing through an opening provided on the side face of the housing. The syringe includes a nozzle and a plunger that forms a sealed space into which the injection object material is injected, and can be propelled to the nozzle by the piston. When the syringe is mounted in the housing, the syringe is fixed so that the plunger of the syringe is arranged at a position facing the piston incorporated in the housing. |
