Abstract:
A compressor-impeller fixing nut has a tubular shape, and includes: a curved-surface shaped portion disposed in a first range from a first end side in an axial direction, the curved-surface shaped portion having an outer diameter which increases toward a second end side in the axial direction and including an outer peripheral surface having a curved shape which protrudes outward in a radial direction in a cross section along the axial direction; and a nut portion disposed in a second range closer to the second end side from the first range in the axial direction, the nut portion having an outer peripheral surface with a nut shape. An expression (D 1 max−D 1 min)/2<L is satisfied, where L is a length of the first range in the axial direction, and D 1 max is a maximum value and D 1 min is a minimum value of the outer diameter of the curved-surface shaped portion in the first range.

Claim (Index 12):
The compressor impeller assembly according to  claim 10 ,\n wherein a recess portion is formed on an upstream end surface of the hub of the compressor impeller with respect to an axial direction, wherein the compressor-impeller fixing nut includes:\n an accommodated portion disposed in a third range from the second end side in the axial direction and accommodated in the recess portion; and \n a flange portion disposed between the nut portion and the accommodated portion in the axial direction and protruding outward in the radial direction, and \n wherein an expression Dc>Dr is satisfied, where Dc is an outer diameter of the flange portion and Dr is an inner diameter of the recess portion.
