Problems solved by technology

[0008] On the other hand, although the divided parts of the filter case are subjected to vibration-welding, the protrusion and the filter case are worn due to friction between each other, thereby causing generation of foreign matter (burrs).

[0051] 1A and 1B, an oil filter 1 includes a housing 11 as a filter housing, a cover 12 as a filter housing connected to the housing 11, and a filter element located between the housing 11 and the cover 12. 13. The oil filter 1 has a longitudinal direction (the direction in which the ribs 133 extend), a transverse direction perpendicular to the longitudinal direction, and a transverse position in the transverse direction.

[0052] In FIGS. 2A , 2B, 3A and 3B, the rectangular housing 11 includes a bottom wall 111 , a side wall 112 extending upward from the outer periphery of the bottom wall 111 , and a flange 113 extending outward from the end of the side wall 112 . The bottom wall 111 has an inlet 111a for oil to enter. The bottom wall 111 has support walls 111b as support members, which are longitudinally aligned with each other.

[0053] The cover 12 includes a top wall 121 , a side wall 122 extending downward from the bottom wall 121 , and a flange 123 extending outward f...

[0063] Hereinafter, similar reference symbols denote similar components, and descriptions thereof are omitted.

[0064] Referring to Figs. 4A, 4B, 5A and 5B, the oil filter 1A will be described.

[0065] The housing 11A includes a support wall 111c as a support member that extends obliquely to a straight line connecting the inlet 111a and the outlet 121a or obliquely to the rib 133 in plan view.

[0066] The cover 12A includes a support wall 121c as a support member extending obliquely to a straight line connecting the inlet 111a and the outlet 121a or obliquely to the rib 133 in plan view. The pair of support walls 121c located in the transverse direction gradually approach each other from the inlet 111a toward the outlet 112a.

[0067] The filter element 13A includes two rows of longitudinally extending ribs 133 . The rib 133 and the support wall 111c coincide with each other with respect to the lateral position. The rib 133 and the support wall 121c coincide with each ot...

[0074] Referring to Figs. 6A, 6B, 7A and 7B, the oil filter 1B will be described.

[0075] The housing 11B includes, as a supporting member, rod-shaped supporting protrusions 111d that extend upward from the bottom wall 111 and are longitudinally arranged. The cover 12B includes, as a support member, rod-shaped support protrusions 121d extending downward from the top wall 121 and arranged longitudinally.

[0076] The support protrusions 111d, 121d and the rib 133 are arranged on a straight line connecting the inlet 111a and the outlet 121a in plan view. Thereby, the support protrusion 111d and the rib 133 coincide with each other with respect to the lateral position. The rib 133 and the support protrusion 111d are opposed to each other with a space S between them 133, 111d. The support protrusion 121d and the rib 133 coincide with each other with respect to the lateral position. The rib 133 and the support protrusion 121d are opposed to each other with a space S between the...

Abstract

A filter media is for fluid to pass therethough. A filter element includes a holding member for holding the filter media. A filter case houses the filter element, having a fluid inlet positioned on a side relative to the filter element, and having a fluid outlet positioned on another side relative to the filter element. A support member extends between the holding member and the filter case. The support member is opposed to one member of the filter case and the holding member with a space between the support member and said one member.

Description

[0001] related application [0002] This application is based on and claims the benefit of and priority from Japanese Patent Application No. 2007-097051 filed April 3, 2007; the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a fluid filter, for example, applicable to automatic transmissions. Background technique [0004] A related oil filter includes a filter housing that houses the filter media and has a combined structure of two split pieces, ribs that hold the filter media to the filter, and a protrusion. housing, and the protrusion extends from the filter housing and contacts the rib (see Patent Document 1). [0005] Oil flows from the inlet into the filter housing, through the filter media and out the outlet of the filter housing. [0006] Patent Document 1: Japanese Published Patent Application No. 2004-353783. [0007] When a negative pressure is created in the filter housing, the filter hous...
