Hose-routing structure and working machine

Abstract

A hose-guiding structure includes at least one hose, a partition including an opening to allow the hose to extend therethrough, a grommet spaced from the partition to allow the hose to extend therethrough, and a hose cover having a tubular shape to cover a periphery of the hose and extending from the grommet to the partition. The hose cover includes a first-end attachment portion at one of opposite ends in a direction of a tube axis of the hose cover, the first-end attachment portion being attached to a peripheral edge portion around the opening in the partition, and a second-end attachment portion at the other of opposite ends opposite the first-end attachment portion, the second-end attachment portion being attached to the grommet such that the grommet blocks an opening portion of the second-end attachment portion. The hose cover is flexible between the first-end attachment portion and the second-end attachment portion.

What is claimed is: 
     
         1 . A hose-guiding structure comprising:
 at least one hose;   a partition including an opening to allow the at least one hose to extend therethrough;   a grommet spaced from the partition to allow the at least one hose to extend therethrough; and   a hose cover having a tubular shape to cover a periphery of the at least one hose and extending from the grommet to the partition; wherein   the hose cover includes:
 a first-end attachment portion at one of opposite ends in a direction of a tube axis of the hose cover, the first-end attachment portion being attached to a peripheral edge portion around the opening in the partition; and 
 a second-end attachment portion at the other of opposite ends opposite the first-end attachment portion, the second-end attachment portion being attached to the grommet such that the grommet blocks an opening portion of the second-end attachment portion; and 
   the hose cover is flexible between the first-end attachment portion and the second-end attachment portion.   
     
     
         2 . The hose-guiding structure according to  claim 1 , wherein a portion of the hose cover that lies between the first-end attachment portion and the second-end attachment portion has a corrugated tubular shape. 
     
     
         3 . The hose-guiding structure according to  claim 1 , further comprising:
 a pressing plate provided at the one of the opposite ends of the hose cover; wherein   the first-end attachment portion includes a pair of flange portions to sandwich the peripheral edge portion; and   the pressing plate is attached to the partition to press one of the pair of flange portions against the peripheral edge portion, the one of the pair of flange portions being opposite the other of the pair of flange portions that is closer to the second-end attachment portion than the one of the pair of flange portions.   
     
     
         4 . The hose-guiding structure according to  claim 3 , wherein the pressing plate includes a restrainer to restrain the first-end attachment portion from moving toward an interior of the hose cover. 
     
     
         5 . The hose-guiding structure according to  claim 1 , further comprising:
 a contact preventing body provided on the opposite side of the partition from the grommet; wherein   the at least one hose includes a plurality of hoses; and   the contact preventing body is configured to prevent the plurality of hoses from coming into contact with each other.   
     
     
         6 . A working machine comprising:
 the hose-guiding structure according to  claim 1 .   
     
     
         7 . The working machine according to  claim 6 , further comprising:
 a hydraulic pump; and   a control valve to control a flow rate of hydraulic fluid delivered by the hydraulic pump; wherein   the partition separates a section in which the hydraulic pump is provided from a section in which the control valve is provided; and   the at least one hose includes at least one hydraulic hose to connect the hydraulic pump and the control valve.   
     
     
         8 . The working machine according to  claim 7 , wherein
 the grommet is provided in the section in which the hydraulic pump is provided; and   the hose cover covers the at least one hose in the section in which the hydraulic pump is provided.   
     
     
         9 . The working machine according to  claim 7 , wherein
 the control valve is provided in a lower space lower than an operator's seat; and   the hydraulic pump is provided in an outside space outside the lower space, the lower space and the outside space being separated by the partition.
