PURPOSE:To provide a brushless motor in which the squeeze-out of adhesive can be prevented by a simple method and a shielding plate can be effectively fixed to a rotor hub. CONSTITUTION:A circular shielding plate 14 for magnetically shielding is mounted at an opposite position of a rotor hub 9 and a stator 3 in a thrust direction. The plate 14 is mounted so as not to squeeze adhesive out of a connecting surface by providing three or more annular grooves 16, 17, 18 on an annular mounting surface of a groove 15, and coating the groove except an outermost periphery and an innermost periphery with the adhesive, thereby preventing the squeeze-out of the adhesive out of the connecting surface. |
