PROBLEM TO BE SOLVED: To prevent leakage of exhaust gas by setting one of valve element parts movable in the axial direction of a valve member. SOLUTION: An exhaust gas recirculation valve 20 comprises an exhaust side path 22 for communicated with an exhaust path part, a valve member having two valve element parts 24a, 25 for opening/closing two holes 22a, 22b penetrating through the exhaust side path, a recirculation side path 23 which is communicated with an intake path of an internal combustion engine and switched its communication with/interception from the exhaust side path by the valve member, and a drive means 28 for driving the valve member. This constitution allows to move, at least, one of the valve element parts in the axial direction of the valve member. |
