Claims

[Scope of utility model registration request]

Male and female rotors rotate parallel to each other and mesh in a non-contact state to pump air in the axial direction, and both ends of these rotor shafts are rotatably supported via bearings, and the overall structure is approximately A pair of side plate members formed in a figure 8 shape, and a driving force that rotates the male and female rotors synchronously, which are assembled on each rotor shaft passing through one of the side plate members. A pump housing having a substantially "8" shaped space in which the drive force transmission mechanism and the male and female rotors are housed in an integrally assembled state via a side plate member; In the plate member, a part of the outer periphery of the arc-shaped part that pivotally supports either the male or female rotor is joined to the space in the housing by a pilot joint, and the other arc-shaped part is fitted into the housing. A screw-type air pump characterized by being stored in a non-rotating state.
