Abstract
An engine hood for a construction machine is configured to be pivoted in a vehicle body back-and-forth direction about a hinge attached as a pivot center to a longitudinal side part of a counterweight. The engine hood includes an engine hood main body, a first operating force applying unit and a second operating force applying unit. The engine hood main body is attached to a vehicle body of the construction machine in a pivotably openable/closable state. The first operating force applying unit is configured to apply force in a direction of opening the engine hood main body until the engine hood main body reaches a vicinity of a predetermined opening angle. The second operating force applying unit is configured to apply force in a direction of closing the engine hood main body when the engine hood main body is pivoted at the predetermined opening angle or greater.
