ABSTRACT:
An apparatus includes a bore tube inside which an imaging space is formed to place a subject, a static field generating section which is placed outside the tube and generates a static field in the imaging space, a gradient field generating section which is placed between the tube and the static field generating section and generates a gradient field to superimpose on the static field, a cover which is mounted to a side end of the static field generating section and forms a vacuum space in a surrounding of the gradient field generating section together with the tube and the static field generating section, wherein the cover is fixed by fixation parts thereof to the static field generating section and a load of an air pressure to be applied on the cover at a different part from the fixation part is received by the static field generating section.
