Abstract
An MRI apparatus having a configuration that reduces vibration of a static magnetic field generating source is provided. A closed vesselof the static magnetic field generating source is provided with a rigid structurefor preventing transmission of vibration generated from a gradient magnetic field generating partto other members via the closed vessel. The rigid structureuses, for example, a connecting partthat connects a faceon the imaging space side and a faceconfronting it. The rigidity of the closed vessel is thereby increased, and therefore vibration transmitted from the gradient magnetic field generating part can be reduced. The connecting part can have a through-hole structure, and in such a case, internal space of through-hole can be used for drawing cables.
