An aspiration motor having a shaft supporting unit is provided to prevent oil from leaking during the rotation of a rotation shaft by modifying a lower end shape of a bushing which supports an impeller and a rotor to the rotation shaft. A shaft supporting unit is formed in the center of a stator supporting plate(83) for rotatively supporting a rotation shaft(90), and includes a boss(85), a bearing sheet(82) making the rotation of the rotation shaft smooth, a sleeve bearing(88) coupled in the boss for rotating the rotation shaft, oil(79) filled in an indent groove of the boss, and a cap(86) preventing the deviation of the sleeve bearing.
