PROBLEM TO BE SOLVED: To improve the turbine efficiency of a variable displacement supercharger 1 while sufficiently securing the durability and reliability of the variable displacement supercharger 1.SOLUTION: On a surface side opposite a first nozzle ring 47 facing surface, a link mechanism 65 is arranged for rotating a plurality of variable nozzles 61 synchronously in the forward/reverse direction. On the surface opposite the first nozzle ring 47 facing surface, an annular support member 77 is integrally provided. On a left side part of a bearing housing 3, an annular storage recessed part 93 is formed to store the link mechanism 65. Inside the support member 77, a communication passage 101 is formed to communicate a turbine scroll flow path 37 with the storage recessed part 93 of the bearing housing 3. |
