Fluid leakage from high to low pressure sides through an annular gap formed between constructional members of a turbocharger and extending radially of a turbine shaft can be prevented. The turbocharger has a sealing device for prevention of fluid leakage from high to low pressure sides through a radially extending annular gap 15 formed between a shroud 10 and a shroud-confronting portion 14 which constitute the turbocharger, the sealing device having a frustoconical disc spring seal member 24 arranged in a pressed manner in the gap 15 between the shroud 10 and the shroud-confronting portion 14.
