特徴とするエアポンプ。 A pump housing consisting of a housing body with a pair of cylindrical spaces formed in the axial direction so as to partially overlap, a front housing, a rear housing, etc. on both ends of the housing body, and a pump housing that is supported by bearings for each of the front and rear housings. and a pair of rotating bodies that are driven to rotate in opposite directions to force air from an inlet to an outlet formed in an overlapping portion of the cylindrical space, and these rotating bodies are rotated in conjunction with each other. and counterweights attached to both ends of each of the rotating bodies to offset the unbalance of the two rotary bodies rotationally driven via the transmission means. An air pump characterized in that an annular groove is formed in a side surface thereof, and bearing portions held on the front and rear housing sides are arranged in each of these annular grooves so as to face the front and rear housing sides.
