成したことを特徴とするエアポンプ。 Both ends of a pair of rotating bodies are rotatably disposed in a pair of cylindrical spaces that partially overlap within the pump housing, and that force feed air from a suction port formed in the overlapped portion of the cylindrical space to a discharge port. In the air pump, the air pump is provided with a counterweight that is loosely fitted into a holding hole recessed in both sides of the pump housing, wherein at least one of the counterweights is located on the input side of the rotating body. An air pump characterized in that a plurality of annular grooves are formed on the outer peripheral surface of the counterweight.
