<P>PROBLEM TO BE SOLVED: To enhance workability during assembly and disassembly of divided cores and improve work efficiency by suppressing deformation of a joint bolt against a load in a shearing direction in a joint portion of the divided cores. <P>SOLUTION: A core 10A is provided with a structure in which divided pieces 10P adjoining each other in the circumferential direction are coupled by a coupling pin 11 of which the axis direction is directed to the width direction of the divided pieces 10P in a position on the radial internal circumference side, and divided sides 10a, 10b formed by the divided pieces 10P, 10P have a first load receiving side 10c and a second load receiving side 10d having predetermined angles with respect to the radial direction in a position in the radial external circumference side outer than the coupling pin 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
