ABSTRACT:
A fluid filter includes a case in which an inflow path, an outflow path, and a drainage path are formed, a cap which is engaged with the case through axial rotation, a biasing device (a coil spring) which biases a filter element housed inside a casing constituted by the case and the cap toward the case side, a rotation restricting device (an abutting portion and a projecting portion) which restricts rotation of the filter element in a fastening direction when the cap is rotated relative to the case in the fastening direction, and a sealing member provided on an axial end surface side of the filter element, which seals the drainage path when the filter element is biased by the biasing device and rotation thereof is restricted by the rotation restricting device.
