Abstract
A transmission fluid filter assembly in which the marginal peripheries of two sheet metal housing members are crimped into a plied peripheral structure which includes therein the abutting edge portions of a folded filter media sheet member along three of the four sides thereof. The plied peripheral structure is formed by bending a first marginal free edge portion of a first sheet metal member over a second marginal free edge portion of the second sheet metal member in compressing relation with respect to the abutting edge portions of the filter media sheet member. Therafter, the plied peripheral structure is angularly bent intermediate the bent-over outer edge and the free edge of the first marginal edge portion in a direction to form an included angle of 90.degree. between the exterior surface of an outer section and the exterior surface of an inner section of the first marginal edge portion.
