<p><P>PROBLEM TO BE SOLVED: To provide a nozzle mechanism for a supercharging system capable of further facilitating formation of a bearing in the bearing formed in a nozzle plate. <P>SOLUTION: In the nozzle mechanism for the supercharging system having a nozzle 33 to regulate a supercharging amount; and a nozzle plate 31 at which a bearing 32 rotatably supporting the shaft 34 of the nozzle 33, the spindle 34 and the bearing 32 are formed into multistages in cross section different in diameter. And, a step part formed in the bearing 32 makes contact with the spindle 34 and has first and second bearings 32a and 32b formed in the bearing 32 and an intermediate part 37 increased in diameter so as not to contact the spindle 34. The second bearing 32b, positioned on the most tip side of the shaft 34, of the first and second bearings 32a and 32b is formed in a manner to extend through a nozzle plate 31. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
