Abstract
A method for manufacturing a compressor scroll that appropriately impinges cavitation bubbles on target regions of a scroll. The method includes the step of water jet peening by jetting cavitation bubbles generated underwater by a water jet at a first side of an end plate (A) of the scroll (), with a center (P, P, P) of the cavitation bubbles being offset from a center (O) of the spiral shape of a wall portion (B) on the end plate (A) and the step portion (Aa) and the stepped portion (Ba) positioned at an outer peripheral portion of the cavitation bubbles (C).
