PROBLEM TO BE SOLVED: To simplify the configuration of a variable displacement supercharger 1 and reduce the manufacturing cost of the variable displacement supercharger 1 by reducing the number of components of a variable nozzle unit 45.SOLUTION: On the radial outside of a supporting hole 49 in the right side face of a first nozzle ring 47, a plurality of guide claws 51 are integrally formed radially at intervals in the circumferential direction. Each guide claw 51 has a sectionally U-shaped guide groove 53 formed on the front end side with drilling work. At the inner edge on the right side face of the first nozzle ring 47, an annular connection protruded part 55 is formed to be connected with the bases of the plurality of guide claws 51. |
