PURPOSE:To increase the impact resistance by forming at least two kinds of adhesive layers of varied thickness when a magnet adheres to the mated surface of a material. CONSTITUTION:A magnet 2 is each provided on a P side bracket 3 and support 4 with an adhesive 5 sandwiching a rotor 1. Here, a concave groove 12 is each provided on the P side bracket 3 and the support 4 as material to be glued so that a thinner adhesive layer 13 with a thickness of t1 and a thicker adhesive layer 14 with a thickness of t2 are formed when the magnets 2 are applied with the adhesive 5. Thus, the thicker adhesive layer 14 can absorb any impact energy generated in a motor in transit. |
