PROBLEM TO BE SOLVED: To provide a supercharger that improves the discharge performance of condensed water produced in a link chamber and suppresses fuel from flowing in the link chamber so that both the discharge performance of the condensed water and the suppression of fuel flowing can be made compatible.SOLUTION: A turbocharger (supercharger) 1 includes a turbine housing 5 in which a turbine wheel 2 rotated by blowing an exhaust gas of an internal combustion engine is stored. The turbine housing 5 includes: a scroll passage 5a for supplying the exhaust gas to the turbine wheel 2; a link chamber 9 for storing a link mechanism 23 which drives a nozzle vane 13 for adjusting a flow of the exhaust gas; and a drain hole 11a making the link chamber 9 communicate with the scroll passage 5a. A lid member 16 (bimetal valve) is arranged near the drain hole 11a which opens a valve when a temperature of the exhaust gas is low and closes the valve when the temperature of the exhaust gas is high. |
