    • 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.

    • PROBLEM TO BE SOLVED: To provide a hammering device, automatically increasing the striking force when rock or the like to be crushed is hard.
      SOLUTION: In this hammering device, a piston 2 having a pressure receiving surface 2u for hammering on which fluid pressure such as oil pressure acts in hammering and a pressure receiving surface 2w for reversal on which the fluid pressure acts in reversal is installed in a cylinder 1 so as to be moved forward and backward in the axial direction. An additional second pressure receiving surface 2v for hammering enabling pressurizing action on the fluid pressure is formed on the piston 2, and a switching means 101 is installed in the device to switch between a state in which the fluid pressure acting on the additional pressure receiving surface 2v can be supplied thereto and a state in which the fluid pressure cannot be supplied thereto. When the rebound of the piston 2 by a reaction caused when the piston 2 hits a chisel 3 at the movement end of the piston 2 is larger than a specified value, the switching means 101 switches the state to one in which the fluid pressure can be supplied to the additional pressure receiving surface 2v for hammering.
