[Scope of Claim for Utility Model Registration] 1. A scroll part that surrounds the turbine wheel to form a turbine casing and partitions the turbine chamber, in order to drive the turbine wheel to rotate by exhaust gas exhausted from an internal combustion engine; In a multi-bore turbocharger having an exhaust gas introduction passage for introducing exhaust gas, the inside of the exhaust gas introduction passage and the scroll portion is expanded and contracted in the turbine axle direction by working fluid along the longitudinal direction and circumferential direction thereof. Turbo supercharging characterized by being provided with a working fluid control means that forms a hollow chamber that changes the cross-sectional area of the passage, expands the hollow chamber when the internal combustion engine rotates at low speed, and contracts when the internal combustion engine rotates at high speed. Machine. 2. The turbo supercharger according to claim 1, wherein the hollow chamber is formed to divide the exhaust gas passage into two along the longitudinal direction and circumferential direction of the scroll portion and the exhaust gas introduction passage. 3. The turbo supercharger according to claim 1, wherein the hollow chamber is provided along the inner wall of the scroll portion and the exhaust gas introduction passage.
