Document Type and Number:
WIPO Patent Application WO/2020/075581
Kind Code:
A1
Abstract:
[Problem] To securely prevent a decrease in filter performance due to filter fabric slipping due to external forces. [Solution] The invention comprises a filter fabric 2 formed in a pouch shape, a framework member 3 disposed on the interior of the filter fabric, and a connecting member 4 connected to a fuel-pump-side member. The framework member includes an inner flange section 15 located on the inner side of the filter fabric. The connecting member includes an outer flange section 22 located on the outer side of the filter fabric. A peripheral edge section 32 of an opening 31 provided in the filter fabric is sandwiched between the inner flange section and the outer flange section, and central sections of the inner flange section and the outer flange section are respectively provided with center holes 13, 21 that serve as communicating paths communicating between the inside and the outside of the filter fabric. The outer flange section is provided with a seal rib 25 that compresses the filter fabric to ensure a seal, a welding rib 26 that joins the framework member and the connecting member by welding, and an anti-slippage rib 27 that suppresses slippage of the filter fabric.
