Abstract
In a medical X-ray CT apparatus, a rotary portion is rotated, and a wind is produced inside the apparatus by the rotation of the rotary portion. An expanded cover portion is forced to vibrate by the wind, and noise is produced. The expanded cover portion is provided with at least one curved member including both ends. The curved member is arranged to extend along a virtual projection line obtained by geometrically projecting a virtual straight line connecting, to each other, the two ends fixed to an outer peripheral edge of an opening of the expanded cover portion onto a surface of the expanded cover portion, and the vibration of the expanded cover portion is reduced.
