Shearing member and filtration device

A shearing member used in a filtration device, the filtration device having:

• a filtering media having a filtering surface and a plurality of filter pores provided on the filtering surface for filtering unfiltered fluid introduced into a primary side,
• a cleaning member abutting the filtering media for cleaning the filtering surface by rotating in a rotational direction,
• a pillar provided at the primary side with its longitudinal direction in the vertical direction which is substantially perpendicular to the rotational direction, to which the cleaning member is attached, and
• a tube body housing the filtering media, the cleaning member, and the pillar;
• the shearing member comprising:
• a first linear member extending in the vertical direction, and
• a second liner member disposed at the upstream side in the rotational direction and extending in the vertical direction;
• wherein
• at least the first linear member is disposed between the filtering surface and a circle defined by the outer circumferential end of the pillar in a radial direction substantially perpendicular to the rotational direction, and
• a distance between the first linear member and the filtering surface in the radial direction is shorter than a distance between the second linear member and the filtering surface in the radial direction.
