Abstract: A probe head rotation mechanism, situated between a spindle and a probe of a coordinate measurement device, includes: a main body frame supported by the spindle; a rotor supported by the main body frame so as to be capable of tilting with respect to an axial center of the spindle; the main body frame; and a motor supported by the main body frame and driving the rotor. A motor main body is arranged away from lying on the axial center of the spindle, and an axial center of the motor is oriented outward in a diameter direction of the spindle.
