An object of the present invention is to provide a bed for a medical image scanning apparatus including a lateral movement device which is light and has less deformation while suppressing a bed height in the lowest position of a top board. A bed for a medical image scanning apparatus includes a base 8, an upper portion frame 2 that supports a top board 1, and a lifting and lowering device 40 that is positioned between the base 8 and the upper portion frame 2 and lifts and lowers the upper portion frame 2, and the lifting and lowering device 40 includes a lateral movement device (a motor 10, a pinion gear 12, and rack 23) which relatively moves at least two members (a rail receiving block 17 and a rotation axis 18, and a rail receiving block 15 and a rotation axis 20) constituting the lifting and lowering device 40 along a direction perpendicular to a longitudinal direction of the upper portion frame 2 in the top board surface of the top board.
