<P>PROBLEM TO BE SOLVED: To provide an electric waste gate valve device in which current flowing in an electric motor in the full-close of a valve is reduced. <P>SOLUTION: A valve body 211 of the waste gate valve 201 is attached to a rocking arm 212 detachably in the valve opening and closing direction and a spring 213 is provided between the valve body 211 and the rocking arm. By providing the spring 213 in this way, the load when the valve body 211 is butted to a valve seat 112 in the full-close of the valve is reduced by the spring 213 to decrease the force loaded on the electric motor 204. As a result, large current is prevented from flowing in the electric motor 204 in the full-close of the valve to prolong the life of the electric motor 204. Further, impact force in the full-close of the valve is reduced to suppress the wear of each part such as the waste gate valve 201. <P>COPYRIGHT: (C)2012,JPO&INPIT |
