Abstract
An object is to easily inject resin into a gap of a laminated core which constitutes a rotating electric machine. Included are: a resin supplying unit which feeds the resin; and a resin injection unit which injects the resin into an axial hole of the laminated core. The resin injection unit has an injection pipe and an elastic ring attached to the injection pipe. This elastic ring is made to firmly attach to the inner periphery of the axial hole; the resin is supplied from the resin supplying unit; and the resin is injected into the gap of the laminated core through the axial hole of the laminated core.
