Abstract
The invention relates to a mounting device for mounting an exhaust gas recirculation valve connected to an exhaust gas reflux passage of an engine. A valve housing is mounted on a cooling water circulating part from an engine block, as well as the valve housing forms a part of a cooling water passage. Therefore, an intense heat of the exhaust gas can be absorbed in and radiated by the cooling water. In this manner, an abnormal over heat of a stepping motor due to the intense heat of the exhaust gas is prevented without forming any cooling water passage around the valve housing.
