Abstract
An injection device comprises: a plunger provided inside a barrel and a nozzle; a seal provided rearward of an injection inlet for the nozzle to prevent a molding material from flowing rearward; and a seal case that holds the seal. The seal case is fixed by the barrel and the nozzle, and has a first inner radial surface that forms a first inner radial hollow section for the plunger to penetrate, and a second inner radial surface that forms a second inner radial hollow section into which the seal is fitted. At least a portion of the first inner radial surface has a female thread section formed thereon.
