Claims

[Claims for Utility Model Registration] 1. Foreign matter blocking pieces that extend vertically on the bottom plate of the strainer and are elongated protrusions in the inner and outer directions of the strainer are arranged in the circumferential direction, and the fluid passages on both sides of the foreign matter blocking pieces are arranged through the vicinity of the tip. In the pump strainer configured to be connected to each other, the inner end surface of the tip of the foreign matter blocking piece in the inner and outer direction is located away from the side surface of the strainer upper member. 2. The strainer according to claim 1 of the utility model registration claim, wherein the outer end surface of the foreign matter blocking piece is an inclined surface that slopes down toward the outer periphery of the strainer, and the lower end of the inclined surface coincides with the outer periphery of the strainer bottom plate. . 3 Utility model registration claim paragraph 1 or 2 in which the strainer and pump stand are integrally made of elastic material
Strainer as described in section.
