Abstract: According to an embodiment of the present disclosure, an exhaust gas treatment apparatus may include: a preprocessor configured to primarily remove harmful substances from exhaust gas produced by combustion; and a postprocessor configured to further remove harmful substances from preprocessed gas, which is the exhaust gas from which the harmful substances have been primarily removed by the preprocessor, wherein the postprocessor may include a postprocessor housing having a preprocessed gas inlet through which the preprocessed gas is introduced and a postprocessed gas outlet through which postprocessed gas from which harmful substances have been further removed by the postprocessor is discharged and forming a flow path of the preprocessed gas therein, and a diffuser disposed adjacent to the preprocessed gas inlet and configured to diffuse the preprocessed gas introduced through the preprocessed gas inlet.

Abstract: Disclosed is a method of assembling a metal clamp and body springs of a wiper blade for vehicles, and an assembly. The method includes forming a plurality of through holes at major sides of the body springs, forming a plurality of protrusions corresponding to the through holes at a major side of the clamp such that the protrusions extend outward from the major side of the clamp, inserting the protrusions of the clamp into the respective through holes of the body springs, fixing the protrusions, which are located in the respective through holes, in the respective through holes by pressure welding or riveting such that the clamp is mounted to the body springs.
