ル。[Scope of Claim for Utility Model Registration] 1. A thermocouple for measuring the temperature of molten resin in the nozzle of an injection molding machine, the thermocouple comprising a protective tube in which the heat-sensitive part of the thermocouple body is sealed at the tip. , a ring-shaped body separated at at least one point is fixed to the protective tube with its tip protruding inward, and the diameter of the ring-shaped body is reduced by a diameter-reducing means provided in the separation part, thereby reducing the diameter of the nozzle. A thermocouple for a nozzle of an injection molding machine, comprising a fastener for fastening a wall surface. 2. In a nozzle of an injection molding machine, a heating means is installed to form an opening on the outer wall surface of the nozzle, and a claim is made at the bottom of a small hole drilled from the opening of the heating means in the outer wall surface of the nozzle. Insert the thermocouple described in item 1 so that the tip of the protective tube is in contact with it,
Further, the protective tube is fixed by a ring-shaped body of a fastener fixed to the protective tube being reduced in diameter from the outer peripheral surface of the heating means by a diameter reducing means of the fastener. An injection molding machine nozzle equipped with a thermocouple.
