Abstract
A wheel loader is provided with a top plate, a plate-like member, a diesel particulate filtering device, and a first duct. The top plate has a first outdoor air intake port. The plate-like member is disposed below the first outdoor air intake port. The diesel particulate filtering device is disposed below the plate-like member. A first end part of the first duct is positioned to the rear of the diesel particulate filtering device. A second end part of the first duct is positioned inside the cooling compartment. A connector is disposed in an air flow generated between a gap and the first end part.
