<p><P>PROBLEM TO BE SOLVED: To reduce in thickness a magnetic field gradient coil, and to increase an open feeling, while suppressing vibrations of the magnetic field gradient coil. <P>SOLUTION: A mold part 17 includes a cylindrical inner side mold part 17a which integrally molds main coils 11-13, and a cylindrical outer side mold part 17b which is provided on a radial direction outer side of the inner side mold part 17a and integrally molds shield coils 14-16. Both ends in the axial direction of the outer side mold part 17b are projected axially toward the outside of the inner side mold part 17a. Thus, the each thickness of both ends in the axial direction of the magnetic field gradient coil 3 are lower than that of an intermediate part in the axial direction. Reinforcement ribs 8 are attached at an interval from each other in a circumferential direction on the inner peripheral surfaces of both ends in the axial direction of the outer side mold part 17b. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
