Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2015-022542 filed on February 6, 2015. The entire contents of this Japanese application are incorporated herein by reference. [0002] The present invention relates to a cover for covering components of an excavator. Background technique [0003] A shovel, which is a construction machine, is often equipped with a diesel engine as a power source. Diesel engines mounted on average-sized excavators require high output. Therefore, a large diesel engine is used for an excavator compared with an engine of a car or the like. In addition, the diesel engine is usually water-cooled, and the radiator is arranged near the diesel engine. [0004] If the diesel engine, the radiator, and the like mounted on the shovel are directly exposed, they will be exposed to wind and rain, and the appearance is not preferable. Therefore, a hood or engine cover is often provided to cover the diesel eng...
