The utility model provides a motor and an air blowing device. The motor comprises a stator core; an insulator; a coil formed by winding a lead wire on the insulator; and a circuit board disposed on one side of the stator core in the axial direction and electrically connected to the coil. The circuit board has a plurality of recesses that are recessed radially outward from an edge portion of a through hole formed in a center portion of the circuit board. The insulator is provided with a clamping part which extends towards the circuit substrate side and is accommodated in the concave part. The recess has an inner side surface. The outer side surfaces of both ends in the circumferential direction of the snap part have an inclination that comes into contact with at least one surface of the inner side surfaces of the recesses. 一种马达及送风装置，马达具有：定子铁芯；绝缘体；在绝缘体上卷绕导线而形成的线圈；以及配置在定子铁芯的轴向一侧并与线圈电连接的电路基板。电路基板具有从形成于中央部的贯穿孔的边缘部向径向外侧凹陷的多个凹部。绝缘体具有向电路基板侧延伸并收纳于凹部的卡扣部。凹部具有内侧面。卡扣部的周向两端的外侧面具有与凹部的内侧面中的至少一侧的面接触的倾斜。
