Abstract: A wheel loader includes an engine, an engine compartment, an injection device, a top plate and a first guide member. The injection device is disposed in the engine compartment. The top plate has a ventilation part. The ventilation part is disposed in a position horizontally away from the injection device. The first guide member has a guide body. The guide body is disposed along the top plate to direct air existing over the injection device to the ventilation part.

Abstract: A vehicle body cover of a work vehicle is provided with an outside ventilation cover part and an inside ventilation cover part. The outside ventilation cover part has outside ventilation holes that communicate with an external space. The outside ventilation cover part is disposed in an inclined manner with respect to the vertical direction. The inside ventilation cover part is disposed to face the outside ventilation holes on the inside of the outside ventilation cover part. The inside ventilation cover part has a rain gutter part and a ventilation part. The rain gutter part is configured to receive water entering from the outside ventilation holes. The ventilation part has inside ventilation holes that communicate with a space on the inside of the inside ventilation cover part. The ventilation part is disposed above the rain gutter part.

Abstract: A linkage mechanism of a work implement installed in a loading vehicle such as a shovel-loader or the like, which is adapted to vertically move a bucket as held in a horizontal state without operating tilt-cylinder, while preserving the function of the Z-bar linkage in the prior art; in which linkage mechanism, when the distance from a pivotable support point (A) between a bucket (3) and a lift arm (1) to a pivotable support point (B) between the lift arm (1) and a bellcrank (5) is represented by (X) and the distance from the above-mentioned pivotable support point (B) to a pivotable support point (O) between the lift arm (1) and a vehicle body (9) is represented by (Y), they are preset so as to fulfil Y/X=.alpha., and also, first and second triangles (.DELTA.ABC, .DELTA.OBE) formed by the liftarm (1) and the bellcrank (5) on the vehicle body side and on the bucket side, as well as a third triangle (.DELTA.ADC) formed by a tilt rod (6) and the bucket (3) and a fourth triangle (.DELTA.
