Zusammenfassung:PROBLEM TO BE SOLVED: To provide a side bracket of a hydraulic breaker which enables the hydraulic breaker to be put on a forwarding attitude where the total height of a topmost section of a boom of a work machine is reduced without removing a rod from a hydraulic breaker body.SOLUTION: In a layout of two pin holes 221 and 223 of a side bracket mounting section 220, at the time of a storage attitude K where a hydraulic breaker 200 is held on an arm side of a work machine 100, an angle α formed by a center O1 of the arm pin hole 221 and a line CL3 connecting a center O2 of the link pin hole 223 and a rod axis line CL1 of a hydraulic breaker body 201 is set at 45° or less so that a rod axis line C1 is parallel to an axis line CL2 of a bucket cylinder 106 provided along an arm 102 of the work machine 100 or a rod head side becomes narrow.SELECTED DRAWING: Figure 3 【課題】ロッドを油圧ブレーカ本体から取り外すことなく、作業機のブーム最頂部の全高を低く抑えた回送姿勢とし得る油圧ブレーカのサイドブラケットを提供する。【解決手段】サイドブラケット装着部220の二つのピン穴221、223のレイアウトは、油圧ブレーカ200を作業機100のアーム側に抱き込む格納姿勢Kのときに、作業機100のアーム102に沿って設けられたバケットシリンダ106の軸線CL2に対し、ロッド軸線CL1が平行または平行よりもロッド先端側が窄まる関係となるように、アームピン穴221の中心O1とリンクピン穴223の中心O2を結ぶ線CL3と油圧ブレーカ本体201のロッド軸線CL1とがなす角αが、45°以下に設定されている。【選択図】図3
