OPERATION ELEMENT OF WORK MACHINE
PROBLEM TO BE SOLVED: To provide a boom and an arm of a structure that does not cover a base end part of a hydraulic cylinder to an extent possible, and capable of securing a strength necessary for a part where the base end part of the hydraulic cylinder is fitted.SOLUTION: A work machine has a pair of support members 60 installed on a boom body 13, the support members having a boss part 64 that supports an end of an arm cylinder 15. A boom 11 capable of moving up and down by using the arm cylinder 15 has a reinforcing member 65 with a cutout part that is cut out to make the pair of support members 60 recede toward a side with the boss part 64, in relation to a hydraulic port P installed on the end of the arm cylinder 15, for reinforcing the support members 60 at a position closer to the cutout part in an area between the boss part 64 and the boom body 13.
【課題】油圧シリンダの基端部を可能な限り覆わない構造で、油圧シリンダの基端部が取り付けられる部位の強度を確保することができるブーム及びアームを提供すること。【解決手段】アームシリンダ１５の一端を支持するボス部６４を有する一対の支持部材６０がブーム本体１３に設けられると共に、アームシリンダ１５による上げ下げ動作が可能なブーム１１において、一対の支持部材６０が、アームシリンダ１５の一端側に設けられた油圧ポートＰに対してボス部６４側へ退くように切り欠かれた切欠き部を有し、ボス部６４からブーム本体１３へ至る領域であって、切欠き部寄りの位置に支持部材６０を補強する補強部材６５を備える。【選択図】図１
