Furthermore, it can also be characterized as a filter housing 1 with a fixed large capacity, which prevents filter deformation or positional change due to filter expansion.

Referring to FIG. 2 , the filter fixing part 70 may adopt any one of a filter expansion margin structure (a), a screw-type filter location restriction structure (b), and a clip-type filter location restriction structure (c).

For example, the filter expansion margin structure (a) encapsulates the filter protrusion 71 in which the hole spacing K is formed by the difference between the inner diameter and the diameter of the inlet pipe 55 and/or the outlet pipe 56 of the housing support 50. It is formed at the lower part of the filter 30, and the capsule filter 30 is restrained by the inlet pipe 55 and/or the discharge pipe 56 after the hole spacing K allows filter deformation to some extent due to filter expansion. By doing so, filter deformation or position change can be prevented.

In addition, the threaded filter position restriction structure (b) forms a screw fastening portion 73 between the inlet pipe 55 and/or the discharge pipe 56 of the housing support 50 and the lower coupling portion of the capsule filter 30. In addition, the screw fastening part 73 maintains a constrained state even in a filter deformation state due to filter expansion, so that filter deformation or position change can be prevented.
