<p><P>PROBLEM TO BE SOLVED: To stably bind fixed piping to a boom by a plurality of clamp members, to suppress damage of the respective clamp members and to improve reliability and durability. <P>SOLUTION: Binding force fixing clamp members 25 and 30 capable of keeping binding force to fixed piping 20 and 22 fixed are positioned and provided near the connection parts 20A, 22A and 22B of the fixed piping 20 and 22 with flexible hoses 23 and 24, and binding force variable clamp members 35 and 39 capable of varying the binding force of the fixed piping 20 and 22 corresponding to the tightening force of bolts 29 and 34 are positioned and provided at the intermediate part in the length direction of a boom 12 separated from the connection parts 20A, 22A and 22B. Thus, the binding force fixing clamp members 25 and 30 parry the displacement of the fixed piping 20 and 22, and the binding force variable clamp members 35 and 39 surely bind the fixed piping 20 and 22 with large binding force. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
