磁性体がはがれるのを防止する。Function: With this configuration, the holding part has multiple holding legs that hold the magnetic material between them, so it is possible to position the magnetic material when pasting it, and the flared end of the tip of the holding leg prevents the magnetic material from being removed from the holding part. Prevent it from peeling off.

り部に接するよう略逆三角形状となっている。EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, reference numeral 3 denotes a holding member, and four radially formed holding legs 4 are provided at 900 intervals for positioning the magnetic body 2 when the magnetic body 2 is attached. A widening portion 5 is formed at the tip of the holding leg 4 to prevent the magnetic body 2 from peeling off from the holding portion 3. The end-widening portion 5 has a substantially inverted triangular shape so as to be in contact with the chamfered portions of the outer diameters 111 of the two adjacent magnetic bodies 2.

れることになる。In the structure mentioned above, if the magnetic body 2 is inserted between the holding legs 4 of the holding part 3 and bonded, the magnetic body 2 can be attached at an appropriate position without using a positioning jig. At the same time, the flared portion 5 prevents the magnetic body 2 from being radially separated from the holding portion 3 due to the centrifugal force during rotation or the magnetic attraction force of the stator magnetic poles. Furthermore, it is possible to bond the magnetic body 2 to the holding feet 4 not only on its inner diameter surface but also on both side surfaces, increasing the bonding area and further preventing peeling.
なお本実施例では磁性体２は４個であるが、４個である
必要はなく、４個以上でもよい。その場合は保持足の数
も同数にすればよい。Although there are four magnetic bodies 2 in this embodiment, the number does not have to be four and may be four or more. In that case, the number of holding legs may also be the same.
