The present invention relates to a massager and a bracket assembly. The present invention integrally forms a cover and a sensor fixing bracket, maintains a constant distance from a temperature sensor about a heating rod, and improves fixability. The present invention includes a massager main body and a massage unit installed in the massager main body. The massage unit includes: a base main body; a roller bracket which is installed in the upper part of the base main body and is combined with a roller for performing massage; a heating rod which is positioned inside the roller and is fixated against the roller bracket; a temperature sensor which senses the temperature of the heating rod; a cover which is combined with the roller bracket; and a sensor fixing bracket on which the temperature sensor is fixated. The cover and the sensor fixing bracket are integrally formed and the temperature sensor is fixated by being inserted into the sensor fixing bracket. The present invention is provided to solve existing problems by providing the massager and the bracket assembly which maintain a constant distance between the temperature sensor and the heating rod and improve fixability.본 발명은 커버 및 센서고정브라켓이 일체로 형성되어, 발열봉에 대한 온도센서의 일정한 거리 유지 및 고정성이 향상된 마사지기 및 브라켓 조립체에 관한 것이다.
