摘要： A filtration filter having a tubular shape, defining a first opening and a second opening facing the first opening, and including a filter base that defines a plurality of through holes arranged in a square grid array. The filter base includes a continuous portion having a first set of through holes of the plurality of through holes, and a non-continuous portion having a second set of through holes of the plurality of through holes. The continuous portion extends in a first direction from the first opening of the filtration filter toward the second opening and extends in a second direction along at least a first portion of a circumference of the filtration filter orthogonal to the first direction. The non-continuous portion has the second set of through holes shifted relative to the first set of through holes of the continuous portion and extends in the first direction.

摘要： In an injection-molded mesh filter, a mesh member for filtering out a foreign substance from a fluid includes: a plurality of horizontal bars; a plurality of vertical bars perpendicular to the horizontal bars; and a rectangular opening defined by an adjacent pair of horizontal bars and an adjacent pair of vertical bars. The horizontal bars and the vertical bars have a substantially ellipsoidal cross-sectional shape. Also, the opening is formed of smooth side faces of the adjacent pair of horizontal bars and smooth side faces of the adjacent pair of vertical bars and the opening at the upstream side of the fluid flow direction flows the fluid in a smoothly-squeezing manner, and the opening at downstream side of the fluid flow direction flows the fluid in a smoothly-expanding manner.
