PROBLEM TO BE SOLVED: To provide a brushless motor in which a thrust plate can be prevented from rotating together with a rotating shaft without forming the thrust plate in rectangular or triangular shape when the thrust plate of the brushless motor is miniaturized. SOLUTION: A circular thrust plate 7 abutting against the end 3b of a rotating shaft 3 and receiving it rotatably, and a thrust cap 8 for holding the thrust plate 7 are provided, and the thrust plate 7 is contained in the recess 8a of the thrust cap 8 such that the center 7x of the circular thrust plate 7 is not aligned with the axis 3x of the rotating shaft 3. With such an arrangement, even a circular thrust plate 7 does not rotate together with the rotating shaft 3 when the thrust plate 7 is made small with the miniaturization of the brushless motor.
