ングを係合させる方式のものがある。 The filter has a bag-like shape and is usually installed in an opening formed in the filter housing. This housing is installed in the liquid flow path. The filter may be held in place in a variety of ways. For example, US Patent Nos. 3503516, 4022093,
4,259,188, or by a plate or cover as disclosed in No. 4,133,769;
There is a method of engaging a filter and a housing as disclosed in Japanese Patent No. 4204966.

は不要である。 The present invention is characterized in that a V-shaped channel that expands upward is formed around an opening provided in the housing for attaching a filter. The filter itself is formed with an annular retaining ring, which serves as the entrance to the filter. This ring has a flexible, curved lip. When the filter is aligned with the opening in the housing, the lip engages the channel formed around the opening, securing the filter in place within the housing. Therefore, no covers, special plates or other filter parts are required to secure the filter.

い。 Using such methods to secure the filter in place within the housing is convenient and effective. Furthermore, the manufacturing cost of the filter device of the present invention is lower than that of a filter device using a cover for supporting the filter. Since the seal between the lip and the opening channel is reliable, there is no need for a separate seal between the housing and the supporting basket used with the filter.
