摘要：
本发明的过滤器(S)具备主体(1)和杯状的过滤网(50)，其中，该主体(1)设有具有流入口(2)和流出口(3)的流道，该杯状的过滤网(50)以能够装卸的方式安装在主体(1)的流道内且具有开口；在主体(1)的侧壁上设有能够放入或取出过滤网(50)的取放用孔(10)，在主体(1)的流入口(2)侧的侧壁内周上形成有具有承受面(21)的承受部(20)，在插入时，过滤网(50)的开口端面(74c)被按压而与该承受面(21)紧密结合，在过滤网(50)的开口边缘部(50a)上形成有凸缘(73)，在与取放用孔(10)相对的侧壁侧突出设置有突起部(40)，该突起部(40)形成供凸缘(73)插入的凹槽(41)，并且，该过滤器(S)设有按压机构(90)，该按压机构(90)从取放用孔(10)侧朝向与取放用孔(10)相对的侧壁侧按压被插入到凹槽(41)中的凸缘(73)，并且将开口端面(74c)按压到承受面(21)上。
摘要（英）：

The invention enables to simplify and miniaturize the structure of a pressing member so as to miniaturize a strainer, and enable the pressing member to suit the small strainer and improve the universality. The strainer (S) is provided with a body (1) which has a flow path having an inlet (2) and an outlet (3), and also with a cup-like screen (50) which is removably mounted within the flow path of the body (1) and which has an opening. An access hole (10) through which the screen (50) can be inserted and extracted is provided in a sidewall of the body (1). A receiving section (20) which has a receiving surface (21) with which an opening end surface (74c) of the screen (50) is brought into close contact by being pressed thereagainst when the screen is inserted in position is formed on the inner periphery of the inlet (2)-side sidewall of the body (1). A flange (73) is formed at an opening edge (50a) of the screen (50). A protrusion (40) which forms a groove (41) in which the flange (73) is inserted is raised from a sidewall which faces the access hole (10). The strainer is provided with a pressing member (90) for pressing the flange (73), which is inserted in the groove (41), from the access hole (10)-side against the sidewall, which faces the access hole (10), to press the opening end surface (74c) against the receiving surface (21).
