A work machine includes a cabin, a machine room, a hydraulic oil tank, a partition wall, and a cover member. The machine room accommodates a drive apparatus to move the work machine. The hydraulic oil tank is provided in the machine room and has an oil gauge. The partition wall separates the cabin from the machine room and has an opening through which the oil gauge is viewable from the cabin. The cover member seals a gap between the partition wall and the oil gauge.

A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve (x)=4.641e.sup.0.34x The value x represents a horizontal direction and the function f(x) represents a vertical direction.

A floor mat arranged in a working machine includes a floor portion, a wall portion arranged on a circumferential portion of the floor portion, and an opening portion arranged on a part of a connecting portion of the wall portion, the connecting portion connecting to the floor portion. The floor mat includes a mat main body arranged on the floor portion, a covering portion configured to cover the opening portion, and an connecting portion configured to connect the covering portion flexibly to a circumferential portion of the mat main body.

A dozer including a cabin includes: an engine room located in front of the cabin, where an engine is internally disposed; and an exhaust gas after-treatment device located above the engine, for purifying exhaust gases emitted from the engine.

To achieve the improvement of maintainability, simplification of structure, upon arranging a cooling fan on an outdoor side of a heat exchanger. To configure such that heat exchangers are arranged so as to face an openable/closable cover in a closed state, in a main accommodating chamber having an opening part which is opened or closed by the openable/closable cover; on the other hand, cooling fans are mounted in the operable/closable cover, and the cooling fans faces heat exchangers to supply cooling air in the closed state of the openable/closable cover; on the other hand, the cooling fans are separated from the heat exchangers in an open state of the openable/closable cover to allow the heat exchangers to be accessible from the opening part.

A construction machine includes an engine, a cooling fan, a hood, a heat exchanger, and a partition plate. The cooling fan is assembled to the engine. The hood includes an exhaust opening. The heat exchanger is arranged between the cooling fan and the exhaust opening. The partition plate forms an air discharge air passage between the heat exchanger and the exhaust opening. The partition plate is inclined upward in a direction from the heat exchanger to the exhaust opening.

A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve (x)=4.641e.sup.0.34x. The value x represents a horizontal direction and the function f(x) represents a vertical direction.

An excavation work machine, in the support structure and opening/closing structure of an upper face cover which covers an upper side of a lateral-part engine chamber on the right side of a swing frame, and the support structure and opening/closing structure of a right exterior cover which covers the right side of the lateral-part engine chamber, includes a first frame part that is provided in the front-rear direction of the swing frame, and a second frame part that is provided perpendicular to the first frame part and that is, at a base end thereof, connected to the first frame part and, at another end thereof, connected to the right exterior cover.

A cover of a work vehicle that defines a housing space for housing devices, including: a panel body having an obverse surface facing an outside of the housing space and a reverse surface facing an inside of the housing space; a plurality of panels arranged such that the surfaces of the panel bodies are positioned on the same plane; a connecting member having a pair of abutting plates abutting the reverse surfaces of a pair of panel bodies adjacent to each other; and a fixing member provided at abutting portions between each panel body and the connecting member, and detachably fixing each of the panel bodies to the connecting member from the obverse surface side.

A urea water tank (27) is formed as a box body that includes a rear inclined surface (28A) that inclines so as to be parallel with a left inclined surface (7C) of a counterweight (7), a front inclined surface (28B) that inclines with a space being left apart from the rear inclined surface (28A) and in substantially parallel with the rear inclined surface (28A) and a front surface (28C) that is formed on front ends of the rear inclined surface (28A) and the front inclined surface (28B) and is formed into a flat surface that is parallel with a left-right direction of an upper revolving body (4). The rear inclined surface (28A) of the urea water tank (27) is disposed along and facing the left inclined surface (7C) of the counterweight (7) and the front inclined surface (28B) is disposed with a gap being left apart from and facing the heat exchanger (9). A cooling air guide passage (33) through which cooling air flows is formed between the heat exchanger (9) and the front inclined surface (28B) of the urea water tank (27).
