Claims

[Scope of utility model registration request]

a retainer seal that has a substantially plate shape and is fitted into the housing, and has a compressor wheel, the shaft being located outside the housing and passing through the shaft;
an insulator formed into an annular shape, attached to the inside of the housing, whose lower edge is separated from the inner wall of the housing, and through which the shaft is inserted through the central opening; and an insulator formed into a substantially cylindrical shape and fitted onto the shaft, and the retainer seal. and a spacer formed with a protrusion that penetrates the insulator and is located between the retainer seal and the insulator, and as the shaft rotates, the protrusion rotates between the retainer seal and the insulator, and the oil in the housing is rotated between the retainer seal and the insulator. An oil leak prevention device for a turbocharger that suppresses oil leakage to a compressor wheel side, characterized in that an oil return hole is formed on the outer peripheral side of the insulator from the tip of the projection. .
