用プラグ。[Claims for Utility Model Registration] 1. In a vent-type plasticizing device having a deaeration port in the cylinder part, the deaeration port is formed by a long hole having a long cross section along the longitudinal direction of the cylinder, and a cylinder length of the same long hole. A vent-type plasticizing device, characterized in that the vent-type plasticizing device is formed on a surface facing a plug whose cross section is smaller than the cross section of the elongated hole and which is inserted and fixed in contact with one end of the elongated hole. 2. A wedge-shaped surface whose one surface matches the surface shape of the screw tip side of the elongated hole formed with a long cross section along the longitudinal direction of the cylinder, and whose lower side cross section of the other surface gradually decreases the distance between the screws toward the screw tip direction. A plug for a deaeration port of a vent-type plasticizing device, characterized by:
