Claims

[Scope of utility model registration request]

An appropriate number of slits parallel to the rotor axis are provided in the radial direction on the outer periphery of the rotor, and the blades are fitted into these slits, and coil springs are used to bias each blade to protrude and come into sliding contact with the peripheral wall of the rotor chamber. In an air motor equipped with a coil spring, when drilling a hole for mounting the coil spring on the outer periphery of the rotor so as to overlap the slit, the center of the hole is shifted to a rearward or forward position in the rotor rotational direction from the center of the slit. An air motor in which the above-mentioned holes are not exposed on the air pressure receiving surface side and the opposite side of the rotor.
