PURPOSE: A filter is provided to stably filtrate by preventing from generating a gap between disk filters or damaging and transforming the disk filter due to a temporary pressure difference of a melted resin. CONSTITUTION: A filter minimizes a damage of a disk filter(130) due to a pressure difference by supporting the disk filter(130) by equipping a fixer in a specific interval at an outer circumference of a pipe(110). Herein, as the fixer, a disk type fixing plate(120) is established, and the fixing plate(120) is formed as the same size of an outer diameter of the disk filter(130), established in 20-1m interval at the outer circumference of the pipe(110). The fixing plate is fixed by establishing a screw mountain in a specific interval at the outer circumference of the pipe(110) as equipping a female screw corresponding to the screw mountain in an inner circumference of the fixing plate.
