VEHICLE MUFFLER

摘要

The present invention relates to a vehicle muffler, and more particularly, to a vehicle muffler including a housing formed with an inlet and an outlet, for introducing and discharging exhaust gas, at both sides; and a noise reduction part provided in the housing for reducing the noise of the exhaust gas, wherein the housing is composed of an upper housing and a lower housing detachably coupled with the upper housing, and the upper housing and the lower housing are made of one selected from engineering plastics, aluminum, and titanium by injection molding or indentation molding. According to the present invention, the vehicle muffler may be formed to be light-weight and the noise reduction part may be effectively and simply disposed in the housing according to the exhaust emission characteristics of an engine instead of being welded in the housing, since the housing formed of the upper housing and the lower housing is made with one selected from engineering plastics, aluminum, and titanium by injection molding or indentation molding. In addition, final complete products can be produced through a simple assembling process of inserting parts together in the fitting manner, and production costs can be minimized due to the simple structure thereof and the noticeably reduced number of processes compared to that of conventional processes.
