To provide a rotor, a motor and a brushless wiper motor which can improve efficiency of work for attachment of a magnet cover and reduce cracking of a magnet.SOLUTION: The rotor comprises: a rotor core 71 that rotates around a rotary shaft line C; magnets 72 arranged on an outer peripheral surface of the rotor core 71; a salient pole 76 formed between the magnets 72 to protrude toward outside in a radial direction; and a magnet cover 73 covering the rotor core 71 and the magnets 72. The magnet cover 73 comprises an end face cover 91 covering one end face side in a rotary shaft line C direction of the rotor core 71 and an outer peripheral surface cover 93 covering outer peripheries of the magnets 72 through a bent part 92. In the rotor core 71 and the end face cover 91 are provided engagement parts 79 and 95 that engage the rotor core 71 with the magnet cover 73 so that the core and the cover cannot rotate relatively. In at least either one of the magnets 72 and the bent part 92 is provided an avoidance part 85 for avoiding the one from contacting with the other.SELECTED DRAWING: Figure 5

    【課題】マグネットカバーの装着作業効率を向上させるとともに、マグネットの割れを低減できるロータ、モータ及びブラシレスワイパーモータを提供する。【解決手段】回転軸線C回りに回転するロータコア71と、ロータコア71の外周面に配置されたマグネット72と、マグネット72の間に径方向外側に向かって突出形成された突極76と、ロータコア71及びマグネット72を覆うマグネットカバー73と、を備え、マグネットカバー73は、ロータコア71の回転軸線C方向一端面側を覆う端面カバー91と、屈曲部92を介してマグネット72の外周を覆う外周面カバー93と、を備え、ロータコア71及び端面カバー91には、ロータコア71とマグネットカバー73とを相対回転不能に係合する係合部79、95が設けられ、マグネット72と屈曲部92との少なくともいずれか一方に、他方との接触を回避するための回避部85が設けられている。【選択図】図5
