<P>PROBLEM TO BE SOLVED: To provide configuration for suppressing generation of cracks and looseness of a ring-like magnet etc. resulting from temperature variation in a rotor which holds the magnet by a holder with a cylindric body part, and a motor with the rotor. <P>SOLUTION: In a rotor 1 of a motor, a magnet 3 is held by a cylindrical body part 25 of a holder 2, and supported with elasticity by support parts (a radial direction support part 6, a peripheral direction support part 7 and an axis direction support part 8) of the holder 2. The support parts (the radial direction support part 6, the peripheral direction support part 7 and the axis direction support part 8) include: contact parts (a radial direction contact part 61, a peripheral direction contact part 71 and an axis direction contact part 81) which contact the magnet 3; and elastic arm parts (an elastic arm part 62 for supporting a radial direction, an elastic arm part 72 for supporting a peripheral direction, and an elastic arm part 82 for supporting an axis direction) for displacing the contact parts in contact directions to the magnet 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
