PROBLEM TO BE SOLVED: To provide a hose holding mechanism which can surely fix hydraulic hoses different in external diameter.SOLUTION: A hose holding mechanism 53 comprises a hose fixing part 19, a cam 48, an eccentric shaft 16, and a fixing block 28. A hose storage chamber 18, into which a hydraulic hose is inserted, and a cam storage chamber 23 are formed in the hose fixing part 19. The eccentric shaft 16 has a central part 39 which is eccentric to both end parts 37, 38. The cam 48 is rotatably supported in the cam storage chamber 23 by the central part 39 of the eccentric shaft 16. The fixing block 28 is elastically energized from the hose storage chamber 18 to the cam storage chamber 23 side and abuts on the outer edge 49 of the cam 48, and is slid to the hose storage chamber 18 side in accordance with rotation of the cam 48 to hold the hydraulic hose in cooperation with a wall surface zoning the hose storage chamber 18. The eccentric shaft 16 is supported by the hose fixing part 19 so as to be rotatable around the center of both end parts 37, 38 as a center of rotation. |
