(Solution by invention) An oil seal and a retainer are installed next to each other in the housing near the extrusion wheel of a double-wheel continuous extruder, and an air is connected to a cooling air source between the oil seal and the retainer. A chamber is formed, and cooling air is blown out from the air chamber through a gap between the retainer and the shaft.

(Example) Hereinafter, an example shown in the drawings will be explained.
The figure shows a sectional view of the main parts of a double-wheel continuous extruder to which the present invention is applied, and 1 and 1' are housings,
3 is a shaft bearing 4 on the housings 1, 1'; 2 is a wheel fitted on the shaft 3; 5;
5' is an oil seal fitted in the housings 1, 1', and 6, 6' are retainers that hold the oil seals 5, 5'. The retainers 6, 6' are provided with air chambers a communicating with a cooling air source at internal portions that contact the oil seals 5, 5'. The cooling air introduced into the air chamber a is blown out from the gap between the retainers 6, 6' and the shaft 3.

(Function) In the double-wheel continuous extruder, the adverse effects of the heat generated during extrusion on the oil seals 5, 5' are alleviated by the cooling air introduced into the air chamber a of the retainers 6, 6'. Even if the flash generated during extrusion attempts to enter through the gap between the retainers 6, 6' and the shaft 3, it is blocked by the cooling air jetted out.
