<p><P>PROBLEM TO BE SOLVED: To improve reliability and productivity by preventing a hydraulic oil blown out from a hydraulic hose from scattering to an engine side with a simple structure not requiring a mounting space. <P>SOLUTION: The fastening part of a hydraulic hose 13 and a hose side joint 14 (fastening cylinder 14B) is constituted to provide a protection cover 21 covering the fastening part. Therefore, even if the hydraulic oil is ejected from between the hydraulic hose 13 and the hose side joint 14, the hydraulic oil is prevented from scattering to the engine side and as the protection cover 21 is cylindrically formed by a knit material with meshes and constituted to cover the fastening part of the hydraulic hose 13 and the hose side joint 14, even a small-scaled hydraulic shovel 1 with no mounting space, the protection cover can be easily mounted thereon, and inexpensively manufactured. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
