<p><P>PROBLEM TO BE SOLVED: To provide a variable turbo supercharger having excellent sealing property of an exhaust turbine with simple structure. <P>SOLUTION: One of rotary shafts 32 of a nozzle vane 31 made as a rotary drive shaft 33, is projected to the outside and is rotated to simultaneously rotate all the nozzle vanes 31 at the same angle via a driving lever 21 fixed to the rotary drive shaft 33 and a connection ring 18. As a result, since the rotary drive shaft 33 is only projected to the outside, the projected part can be easily and surely sealed to improve sealing property and the durability. Since a rotary motion of the rotary drive shaft 33 as it is can be made into rotary motions of the nozzle vane 31, a transmission structure of driving force can be simplified. <P>COPYRIGHT: (C)2003,JPO</p> |
