FILTER DEVICE

摘要

A filter device includes a first connection part 1 adapted to be connected to a fuel pump; a second connection part 21 adapted to be connected to a path for a returned portion of fuel; and a filter member 3 having an inner space 30 communicating with an inlet port 10 of the first connection part 1 and an outlet port 20 of the second connection part 2. A tubular member 22 has a leading edge 22a formed with the outlet port 20 of the second connection part 2. The leading edge 22a of the tubular member 22 is opened to be disposed in the inlet port 10 of the first connection part 1 so as to have a gap between an outer peripheral surface 22b of the tubular member 22 and an opening edge 10a of the inlet port 10 of the first connection part 1.
