エアポンプ。 A pump housing consisting of a housing main body having 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. a pair of rotating bodies that are rotated in opposite directions to force air from the suction port formed in the overlapping portion of the cylindrical space to the discharge port, and these rotating bodies are rotated in conjunction with each other. A driving force transmitting means connected to the rotating body, and a counterweight attached to each end side so as to offset the imbalance of both rotating bodies rotationally driven via the transmitting means, and these counterweights, 1. An air pump comprising a cup-shaped main body having a central hole and having a cup-like shape as a whole, and a weight body fitted and held inside the cup-shaped main body.
