An operation unit for a construction machine, comprising:
- a floor;
- an operation seat provided on the floor;
- a console box provided on a lateral side of the operation seat;
- a pilot valve provided within the console box;
- a plurality of hoses connected to the pilot valve and arranged at least in an area from the pilot valve to the floor while being bundled together;
- and
- a flexurally deformable hose cover covering a plurality of over-floor portions which are respective portions of the hoses between the pilot valve and the floor, the hose cover including:
- a sheet-shaped cover member having opposite wrapping ends and being wrappable around the over-floor portions with an interconnection of the wrapping ends;
- and a fastener adapted to make the interconnection of the wrapping ends to hold the cover member in a tubular shape,
- wherein:
- the over-floor portions are arranged so as to form a bundle thereof having a greater diameter on the side of the pilot valve than on the side of the floor;
- and
- the cover member has an upper cover section which covers a region of the over-floor portions on the side of the pilot valve and a lower cover section which covers a region of the over-floor portions below the upper cover section, the cover member being wrapped around the over-floor portions in such a shape that the upper cover section has a diameter greater than that of the lower cover section,
- wherein the upper cover section of the cover member has a portion widthwise protruding beyond the lower cover section, the protruding portion being folded into a plurality of pleats to form a folded portion, and wherein the folded portion has a lower end bound to allow an upper end of the folded portion to be spread out like a folded fan.
