<p>PROBLEM TO BE SOLVED: To improve the set of takeoff point set of an actuator rod, a lever arm, and a waste gate valve by allowing a prescribed relative rotating movement between a first extension part for forming a first rod end part and a second part for forming a second rod end part within one plane vertical to the axial line of the first extension part. SOLUTION: An actuator rod 17 is linked with a valve 12 through a lever arm 19, and the lever arm 19 is mounted on the end part of a valve stem 20 inserted to a bush 21 within a turbine housing 3. The actuator rod 17 has, on the end connected to the lever arm 19, a first extension part for forming a spherical first actuator rod end part 17a and a second part for forming a cylindrical second rod end part 17, and a prescribed relative rotating motion is allowed between the first and second parts. According to this, the takeoff point set of the actuator rod 17, the lever arm 19 and a waste gate valve can be improved.</p> |
