An insulator structure of a motor, includes: a stator core having a plurality of protruding tooth portions which are disposed along an inner periphery of the stator core or an outer periphery of the stator core; a pair of first and second insulators respectively mounted to a first end portion and a second end portion in an axial direction of the stator core, wherein a plurality of cover portions are provided for each of the pair of the first and second insulators so as to cover the plurality of the respective tooth portions; and a winding wound around a tooth portion of the tooth portions covered with the respective cover portions, the winding being capable of causing a magnetic force to the tooth portion by an energizing; wherein with the pair of the first and second insulators, the cover portion's second head end portion in an axial direction of the first insulator in the axial direction and the cover portion's first head end portion in an axial direction of the second insulator in the axial direction mate with each other, the cover portion having the head end portion in the axial direction provided with a first fitting portion and the cover portion having the head end portion in the axial direction provided with a second fitting portion fittable with the first fitting portion are provided for each of the pair of the first and second insulators, the cover portion provided with the first fitting portion and the cover portion provided with the second fitting portion are so disposed as to face each other in such a configuration as to interpose therebetween a center axis of the stator core, and the first insulator and the second insulator which is substantially the same as the first insulator in configuration and is reversed in the axial direction are configured to face each other, such that the first fitting portion of the first insulator mates with the second fitting portion of the second insulator.
