PROBLEM TO BE SOLVED: To simplify the configuration of a variable nozzle unit 43 and reduce the manufacturing cost by reducing the number of components of the variable nozzle unit 43.SOLUTION: A plurality of first guide grooves 47 are formed at equal intervals along the circumferential direction in a shroud ring 45. A plurality of second guide grooves 55 are formed at equal intervals along the circumferential direction in a nozzle ring 53. A slide pin 59 of each variable nozzle 57 is guided and supported slidably by the corresponding first guide groove 47 of the shroud ring 45. A slide projection 61 of each variable nozzle 57 is guided and supported slidably by the corresponding second guide groove 55 of the nozzle ring 53. |
