A wheel loader includes a cooling chamber, which houses a cooling fan and a cooling device, and a grill through which a cooling air obtained by the cooling fan passes. The grill includes a frame, which is provided by framing four side components, and a ventilation portion, which is made of a punching metal and which also has a plurality of air intakes. The ventilation portion is provided inside the frame, and it is a stepwise member with vertically arranged steps that are created by plastic working the punching metal. The ventilation portion has a three-dimensionally curved surface that bulges bidirectionally toward an outside of the cooling chamber.
