ABSTRACT:
A filter adapted to be connected to a suction hole of an intank pump provided in a tank for storing a liquid and adapted to pump the liquid out of the tank. The filter includes a mesh bag and an elastic frame surrounded by the mesh bag for elastically pressing a lower portion of the mesh bag against a bottom inner surface of the tank. The elastic frame is formed with a flat plate adapted to uniformly press the lower portion of the mesh bag against the bottom inner surface of the tank. Accordingly, local wearing of the mesh bag due to the pressure applied thereto by the frame can be prevented.
