Abstract: A method of properly aligning a sliding side door on a vehicle includes first preparing a prototype vehicle and determining how far out of alignment the door is to the body of the prototype vehicle. This amount of misalignment is then used to adjust the attachment position of an anchor plate to a sliding side door of the vehicle, so that the anchor plate is attached at a desired position to the production vehicle, which causes there to be no misalignment between the sliding side door and the body of the production vehicle. A jig is used to hold the anchor plate at the desired location while welding the anchor plate to the door. A roller assembly is then attached to the anchor plate and to a rail on a body of the vehicle.

Abstract: A filter material fabricated by mixing 10 to 30% by mass of first fibers having a fiber diameter of 10 to 40 ?m, 40 to 80% by mass of second fibers obtained by crimping natural fibers having a fiber diameter of 10 to 40 ?m, and 10 to 30% by mass of third fibers having a fiber diameter of 5 to 10 ?m. The filter material has low pressure loss a high dust holding amount, and high dust filtration efficiency.

Abstract: A filter element has an upstream-side filter layer and a downstream-side filter layer. The downstream-side filter layer is attached to the upstream-side filter layer. A non-woven fabric made of resin fibers formed by a spinning process constitutes the upstream-side filter layer. The resin fibers have an average diameter within a range of 2.5 ?m and 10 ?m. The non-woven fabric has a weight per unit area within a range of approximately 2.5 g/m2 to 15 g/m2. The downstream-side filter layer has a finer mesh than the mesh of the upstream-side filter layer.
