A spray arm locking device of a dish washer includes a water feeding guide having a limiter for preventing a spray arm from being divided; a frame locked to the water feeding guide and having a spray arm for spraying by rotating the cleaning water fed through the water feeding guide and a plurality of inserting holes; a spacer ring having a supporting rib which is installed on a gap and inserted to the inserting hole to contact with the surface of the limiter, and thus maintains the locking condition of the water feeding guide and the frame, thereby attaching/detaching the frame to the water feeding guide.
