A vane air motor configured to prevent uneven wear of vanes is provided. The vane air motor has a cylindrical member having a rotor chamber (19) defined by a circular cylindrical inner peripheral surface (11), and a vaned rotor. A plurality of air discharge openings (50) are provided over a predetermined length range in the axial direction of the rotor chamber. Each pair of axially adjacent air discharge openings are spaced from each other and overlap each other as seen in the circumferential direction of the rotor chamber. |
