PURPOSE: A position fixing device of a hydraulic breaker is provided to obtain reliability to an operation and durability of a product by suppressing the vibration in a forward and backward direction of a body to prevent the damages of a case and by preventing a nut from being released by the vibration of the body. CONSTITUTION: A position fixing device of a hydraulic breaker comprises a coupler(3), a pressurizer(1), and first and second bushings(21,22). A coupler is connected through a first and second coupling holes(201,202) symmetrically formed on both sides of a case(200). The pressurizer is inserted inside the case by being connected to the coupler, a coupling member coupled to a body(100) is attached to the external surface of the pressurizer. The first and second bushings are connected to the first and second coupling holes and both sides of the coupler, and a front end of the first and second bushings is closely attached to both sides of the pressurizer.
