。[Claims for Utility Model Registration] (1) A device comprising a static magnetic field generating means consisting of a pair of permanent magnets and a magnetic yoke that magnetically couples the magnets and forms a substantially sealed space, wherein a side surface of the magnetic yoke is A nuclear magnetic resonance imaging device comprising an opening large enough to allow a subject and a component larger than the subject to be inserted therethrough, and the outer edge of the opening being covered with a removable high permeability magnetic member. (2) The opening consists of an opening formed in the yoke itself, which is reduced in size by a base member fixed to the opening so as to protrude into the opening, and the lid member is screwed to the protrusion of the base member. A nuclear magnetic resonance imaging apparatus according to claim (1) of the utility model registration, characterized by:
