A dishwasher uses washing water containing microbubbles. The dishwasher includes a flow path forming rib that defines a washing water flow path inside an upper body and a lower body of a spray arm. The dishwasher further includes a fusion rib for fusion coupling the upper body and the lower body to effectively secure a flow path structure and simplify a fastening structure.

The rotor of the invention has two legs fastened to a rotary base, wherein the legs are provided with asymmetrically arranged boreholes facing upwards and boreholes facing downwards, wherein the boreholes facing upwards have the shape of an ellipse, while the boreholes facing downwards have a circular shape. The boreholes facing upwards and the boreholes facing downwards are formed, such that the jets from the boreholes facing upwards act vertically upwards and the jets from the boreholes facing downwards act vertically downwards, i.e., in a direction 90° with respect to the axis of the legs.
