<p><P>PROBLEM TO BE SOLVED: To improve durability of a hydraulic pipeline by preventing an external force applied on a sensor cover from being transmitted directly to the hydraulic pipeline. <P>SOLUTION: A mounting seat 13 having a female screw hole 13A is fixed on a tube 12A of a boom cylinder 12. A fixing bolt 24 inserted into a bolt insertion hole 21C of a bracket 21 fixed on a rod-side hydraulic pipeline 18 and a bolt insertion hole 23C of a sensor cover 23 is screwed into the female screw hole 13A of the mounting seat 13. The bracket 21 and the sensor cover 23 can be fastened together to the mounting seat 13 by the fixing bolt 24. The sensor cover 23 can be fixed firmly on the mounting seat 13, so that the external force to be applied on the sensor cover 23 can be received by mainly the mounting seat 13. Therefore, the external force to be applied on the sensor cover 23 is prevented from being transmitted directly to the rod-side hydraulic pipeline 18, and the durability of the rod-side hydraulic pipeline 18 can be improved. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
