<p>Disclosed are an oil filter and filter element which make it possible for oil to be reliably drained to a drainage passage when a filer element is replaced etc. An oil filter (1) comprises a housing (5) and a cap member (6) which form a space accommodating a filter element (7). A locking part (23) which locks the filter element is disposed in the cap member. A communicating part (11) connected to an inner circumferential space of the filter element, a ring-shaped drainage groove part (12) surrounding the communicating part, and a ring-shaped inflow-side groove part (13) surrounding the drainage groove part are disposed in the bottom part of the housing. A gasket (35) is disposed in the bottom part of the filter element and comes into contact with a partition wall (14) to control flow of pre-filtering oil to the drainage groove part. When the cap member is taken out of the housing, the filter element and the cap member are moved together by means of the locking part, and the pre-filtering oil is drained from a gap between the gasket and the partition wall into the drainage groove part.</p> |
