Thus, the middle site of the boom cylinder hydraulic hose 33 can be moved along left and right side face plates 14, 15 of the swing post 11 by left and right arm parts 43, 44 of the hose holding member 41. As a result, hydraulic hoses 33A, 33B of the boom cylinder hydraulic hose 33 are prevented from being held between a boom 4A and the swing post 11, therefore protecting the boom cylinder hydraulic hose 33. |
