<p><P>PROBLEM TO BE SOLVED: To avoid sticking of a nozzle vane without increasing an amount of gas leak. <P>SOLUTION: In the variable displacement type supercharger, portions of a first annular side wall surface 51 and a second annular side wall surface 52 on the outer peripheral side of the nozzle vane 31 rather than the rotating center position thereof are formed as conical inclined surfaces 51A and 52A so that a gap Ga between one side face 31A of the nozzle vane 31 and the first annular side wall surface 51 and a gap Gb between the other side face 31B of the nozzle vane 31 and the second annular side wall surface 52 are enlarged toward the outer peripheral side of a gas inlet space 25 from the rotational central side of the nozzle vane 31. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
