The invention relates to magnetic resonance imaging device and a gasket tray, and the static magnetic field can be maintained to be uniform. The magnetic resonance imaging device is provided with a gasket accommodating portion and a structural body. Metallic gaskets are accommodated in the gasket accommodating portion in a stacked manner. Furthermore, when the gasket accommodating portion is inserted into an inclined magnetic field coil, at least one inner wall of two inner walls which are arranged oppositely in the axial direction is inclined relative to a surface which is vertical to the axial direction. In addition, the structural body is arranged on the gasket accommodating portion and can move along the gasket accommodating portion in an inclined manner.
