PROBLEM TO BE SOLVED: To increase operation efficiency of an assembling operation for a variable nozzle unit 45 sufficiently while stabilizing an operation of the variable nozzle unit 45 by suppressing a nonsmooth movement of a variable nozzle 57 during an operation of a variable capacity type supercharger.SOLUTION: Each first support hole 49 of a shroud ring 47 has two first bearing parts 49a, 49b supporting a first nozzle shaft 59 rotatably on both axial sides, and each second support hole 55 of a nozzle ring 51 has two second bearing parts 55a supporting a second nozzle shaft 61 rotatably, a fitting clearance between the first bearing part 55a and second nozzle shaft 61 being set to be larger than a fitting clearance between the first bearing parts 49a, 49b and first nozzle shaft 59. |
