    • 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.
    • 一种传输流体过滤器组件,其中两个钣金壳体构件的边缘周边被压接成合股的外围结构,其中包括沿其四个侧面中的三个侧面折叠的过滤介质片构件的邻接边缘部分。 通过在第二金属板件的第二边缘自由边缘部分上相对于过滤介质片材的邻接边缘部分压缩的关系弯曲第一金属板件的第一边缘自由边缘部分而形成合股周边结构。 后者,合股周边结构在弯曲的外边缘和第一边缘边缘部分的自由边缘之间的角度上弯曲成一个方向,以在外部部分的外表面和外部表面之间形成90度的夹角 第一边缘部分的内部部分。
