。 The shaft of the needle valve is loosely fitted into the through hole provided in the axial direction of the nozzle of the valve housing, which is fixed to the base of the nozzle of the injection molding machine and has a resin flow path, and a pusher is attached to the tail end of the needle valve. In the needle valve device of an injection molding machine, in which the tip valve part of the needle valve opens and closes the nozzle opening by moving the pusher back and forth, a conical surface part is formed in the middle part of the needle valve, and the valve housing A conical hole with a slightly gentler slope than the conical surface of the needle valve is provided at the tip of the through hole that guides the needle valve, so that the conical surface of the needle valve is in linear contact with the conical hole of the valve housing. A needle valve device for an injection molding machine featuring:
