Title: FILTER DEVICE
Abstract:
According to the present invention, air present inside can be reliably evacuated, and a liquid to be filtered can be prevented from leaking to the outside of a tank. A liquid flowing into a case 10, which is protrusively provided inside the tank, passes through a filter element 20, which is provided inside the case 10 so that the upper end surface thereof contacts the rear surface of a lid body 30, and is discharged into the inner space of the filtering material. Formed in the lid body 30 is an outflow part 35 which provides communication among a middle portion space of the filtering material, the inside of the tank 100, and the outer space of the case 10. A liquid flows into the outflow part 35 from a first opening H1 disposed at a position overlapping an outlet port formed in the upper end surface of the filter element 20, and the liquid that has flowed through the outflow part 35 flows out from a second opening H2 disposed between a side surface of the tank 100 and a side surface of the case 10.
