PROBLEM TO BE SOLVED: To provide a bracket for a breaker, which bracket can prevent noise generated in the breaker, such as a hydraulic breaker, and also can promote the dissipation of heat generated in the breaker. SOLUTION: The hydraulic breaker 10 having a chisel 12 and a breaker body 11 for vibrating the chisel 12 is fixed to the bracket 20. The bracket 20 has a noise insulating section 30 for covering the noise generating portion in the breaker body 11, which portion generates noise when the vibration is applied to the chisel 12. Further, the bracket 20 has two supporting plates 41, 42 facing to each other. The noise insulating section 30 and a connecting section 50 for connecting the bracket 20 to an arm of a construction machine are fixed between two supporting plates 41, 42. Further, urethane rubber plates 36, 37 are arranged so as to fill the gap between the breaker body 11 and the noise insulating section 30. COPYRIGHT: (C)2005,JPO&NCIPI
