PURPOSE:To enable the titled nozzle to perform temperature control of a resin outflow hole easily and stably, by a method wherein the resin outflow hole is arranged on a position where the temperature of a nozzle body becomes highest, a sprue bushing is formed so that the same is fitted in a bushing fitting part and is capable of making facial contact with the tip of the resin outflow hole. CONSTITUTION:At the time of mold clamping, a sprue bushing 5 and bushing part 4 are fitted each other and facial contact of a nozzle body 2 and mold 6 is performed each other along with a matter that the facial contact of said sprue bushing 5 and nozzle tip 3 is performed each other. When an electro-magnetic induction coil 1 is electrified, the nozzle tip 3 forming a resin outflow hole 3a shows the highest temperature as compared with the other part. When electrification is interrupted and nozzle with the other part. When electrification is interrupted and nozzle touching is made to perform, as the facial contact of the nozzle tip 3 is performed directly with the sprue bushing 5 at a wide area and the tip of the nozzle body 2 performs the facial contact with the sprue bushing 5 and mold 6 at the wide area, the titled nozzle is cooled efficiently. The temperatures of the nozzle tip 3 at times of heating and cooling are detected precisely by a temperature sensor 8 buried in said nozzle tip 3.
