- the columnar portion 53a is a portion that fits into the cylindrical communication portion SP, and includes an O-ring 53c in the middle of the height direction.
- the O-ring 53c is in close contact with the inner wall of the communication part SP and the peripheral surface of the columnar part 53a in a state where the columnar part 53a is inserted into the communication part SP, and seals the communication part SP in an airtight state.
- the flange portion 53b is formed integrally with the lower end of the cylindrical portion 53a.
- the flange portion 53b is configured by a circular plate portion larger than the diameter of the columnar portion 53a and the diameter of the insertion port 52e provided in the substrate 52b.
- the flange part 53b is accommodated in the clearance gap formed between the ceiling part 31a which closes the upper end of the core material 31, and the board
- the columnar portion 53 a is provided so as to protrude above the holding plate 52. In this state, the plug member 53 is movably attached within a clearance range determined by the size of the gap and the diameter of the insertion port 52e.
- the cylindrical portion 53a of the plug member 53 becomes the communication portion SP.
- the communication portion SP is fitted and sealed in an airtight state. That is, the space in the communication part SP is divided by the O-ring 53c.
- the movable member 51 moves to the ceiling portion 21 side until the flange portion 51c is positioned in the vicinity of the ceiling portion 21.

- the cap member 6 When removing the filter element 7, if the cap member 6 is rotated in the removal direction, the cap member 6 moves in a direction away from the housing 5. At this time, since the coil spring 26 is extended, the movable member 51 is kept pressed against the housing 5 by the reaction force. As a result, the communication part SP moves in the direction of detaching from the cylindrical part 53a.
- the sealing portion of the communication portion SP by the plug member 53 is released, and external air is released from the ceiling portion 21 of the cap member 6 into the accommodation space. Therefore, it is possible to suppress a problem that oil in the accommodation space leaks from the connection portion between the cap member 6 and the housing 5. Moreover, since the communication part SP is sealed or made into the communication state by the plug member 53 provided on the upper surface of the filter element 7, the sealing state of the communication part SP can be controlled with a simple configuration.
- FIG.16 and FIG.17 is a figure explaining the oil filter 1 of 4th Embodiment.
- This oil filter 1 is obtained by projecting a cylindrical portion 31b on the upper surface of the ceiling portion 31a of the core member 31 in place of the plug member 53 in the oil filter 1 of the third embodiment. That is, the core material 31 is used as a plug member.
- the cylindrical portion 31b is configured in the same manner as the cylindrical portion 53a included in the plug member 53a of the third embodiment, and an O-ring 31c is provided in the middle of the height direction.
- the gasket 35 is separated from the upper surface of the partition wall 14, so that the oil before filtration flows into the drain groove 12 from the gap between the gasket 35 and the partition wall 14 as indicated by an arrow E. And the oil which flowed into the drain groove part 12 is collect
- the cylindrical portion 31b is integrally provided on the upper surface of the ceiling portion 31a of the core member 31, so that the configuration can be simplified and the burden during assembly work Can be reduced.
- the present invention is not limited to this configuration.
- the structure which accommodates about 1/3 from the lower side of the filter element 7 may be sufficient, and the structure which accommodates about 2/3 from the lower side may be sufficient. In short, it is sufficient that at least the bottom of the filter element 7 is accommodated.
- the male screw and the female screw are used.
- the present invention is not limited to this configuration.
- the housing 5 and the cap member 6 may be fixed using a metal band.
- the gasket 35 in each of the above-described embodiments, is configured to cover most of the lower end plate 34. However, the gasket 35 may be provided at least at a portion where the upper end of the partition wall 14 abuts. For this reason, you may form in a ring shape. In the first embodiment, when the gasket 35 is formed in a ring shape, an O-ring may be provided on the outer peripheral surface at the upper end of the communication portion 11.
- the side edge of the upper end plate 33 included in the filter element 7 is locked by the locking claw 28, but the configuration is not limited thereto. Any configuration can be adopted as long as the upper part of the filter element 7 can be fixed.
- the coil spring 26 may be a spring having another configuration as long as the filter element 7 can be pressed to the housing 5 side.
- the cylindrical portions 31b and 53a are configured to include the O-rings 31c and 53c, but instead of the O-rings 31c and 53c, protrusions that go around the outer peripheral surfaces of the cylindrical portions 31b and 53a may be formed.
