Abstract
It is an object of the present invention to provide a vane rotary type air pump in which a pump mechanism and a drive motor are directly connected to each other and low noise is realized. In the vane rotary type air pump in which a cylinder (), a rotor () and a vane () are sandwiched between a front plate (not shown) and a rear plate (not shown), an opened end () of the vane groove () is provided in a reversed rotation direction region of the rotor () with respect to straight line connecting a center O of the rotor () and the closed end () of the vane groove (). That is, a 'stroke' type vane disposition is employed. With this noise of the air pump is reduced.
