an engine; a chassis, at sides of which tires are provided; an engine room in which the engine is mounted on the chassis, the engine room being provided behind the driver's cab; front portion structures respectively standing at left and right positions of a surface of the engine room, the surface being located at the driver's cab side; rear portion structures respectively standing at left and right positions of a surface of the engine room, the surface being opposite to the surface located at the driver's cab side; and a coupling structure that couples upper portions of the front portion structures to upper portions of the rear portion structures and forms a peripheral device installation space at an upper portion of the engine. ## Claims ### Claim 1 A wheel loader comprising: a driver's cab; an engine; a chassis, at sides of which tires are provided; an engine room in which the engine is mounted on the chassis, the engine room being provided behind the driver's cab; a cooling room in which a radiator and a fan are provided, the cooling room being provided behind the engine room front portion structures respectively standing at left and right positions of a surface of the engine room, the surface being located at the driver's cab side; rear portion structures respectively standing at left and right positions of a surface of the engine room, the surface being opposite to the surface located at the driver's cab side; and a coupling structure on which an exhaust gas purifier is mounted, the coupling structure coupling upper portions of the front portion structures to upper portions of the rear portion structures above the engine, wherein the exhaust gas purifier is provided between the coupling structure and an upper cover provided at an upper portion of the engine room, an air cleaner is provided behind the exhaust gas purifier, and a divided plate is provided between the exhaust gas purifier and the air cleaner. ### Claim 2 (depends on 1) The wheel loader according to claim 1, wherein: the engine room includes side covers covering side portions of the engine room, respectively; and the front portion structures are provided immediately behind the driver's cab and include supporting portions for opening and closing the side covers in a horizontal direction. ### Claim 3 (depends on 1) The wheel loader according to claim 1, wherein the front portion structures, the rear portion structures, and the coupling structure are integrated with one another to form a frame structure of the engine room. ### Claim 4 (depends on 1) The wheel loader according to claim 1, wherein: the front portion structures are provided with a front portion coupling member coupling the front portion structures standing at the left and right positions; and the front portion coupling member includes a peripheral device installation shelf on which a hydraulic accumulator is mounted. ### Claim 5 (depends on 1) The wheel loader according to claim 1, wherein the dividing plate includes a heat insulator configured to prevent heat of the exhaust gas purifier from being transferred to the air cleaner. ### Claim 6 (depends on 1) The wheel loader according to claim 1, wherein the rear portion structures are provided with a dividing wall coupling the rear portion structures standing at the left and right positions. ### Claim 7 (depends on 1) The wheel loader according to claim 1, wherein: the engine room includes an upper cover covering an upper portion of the engine room; the upper cover includes a muffler configured to discharge an exhaust gas; and the muffler includes an opening portion through which air around the exhaust gas purifier is discharged to an outside by an upward flow generated by the exhaust gas discharged from the muffler. ### Claim 8 (depends on 2) The wheel loader according to claim 2, wherein each of the side covers is formed integrally with a fender for the tire.
