PURPOSE: A nozzle device for injection molding is provided to prevent a resin from being solidified and stuck on a wall surface of a runner because turbulence is formed with a turbulence forming member into a flow of the resin. CONSTITUTION: A nozzle device for injection molding comprises a manifold(20), one or more nozzles(40), and a turbulence forming member(50). The nozzles are joined to the lower part of the manifold and inject the resin injected into the manifold to a cavity(15) of a mold. A runner(25) is formed in the inside of the manifold and guides the resin injected into the manifold to the nozzles. The turbulence forming member is mounted in one side of the runner and forms the turbulence with a flow of the resin injected into the runner. The turbulence forming member comprises a body and a spiral groove. The body is formed correspondently to a shape of the runner. The spiral groove guides the resin so that the turbulence of the resin is formed.
