ABSTRACT:
An apparatus for securing magnetic poles of magnet-type rotating machines has a cylindrical fixed frame, a plurality of permanent magnets attached to the inner side of the fixed frame at a predetermined distance in the circumferential direction, and a positioning member defined by an elastic member having a substantially U-shaped cross section, the positioning member being disposed in the space between each pair of adjacent permanent magnets in such a manner as to abut against the opposing end faces of the pair of adjacent permanent magnets to thereby effect positioning of the permanent magnets in the circumferential direction. The positioning member is provided with bent portions which are formed near its open end, the bent portions extending inwardly of the positioning member. The bent portions of the positioning member prevent another positioning member from entering the inside of this positioning member, so that it is possible to prevent fitting engagement between stacked positioning members before they are assembled to the fixed frame.
