Abstract

Provided is a construction machine capable of smooth exhaust and suppression of a leak of noise from an engine room, including an engine guard defining an engine room, a cooling fan disposed in the engine room, a projection element projecting upward beyond the engine guard, and an exhaust duct. The exhaust duct has a bent shape including a first duct section extending along an axial flow direction of the cooling fan from an upstream end portion surrounding a duct inlet to a connection portion and a second duct section extending upward from the connection portion and surrounding a duct outlet opened upward, also including an engine concealment section obstructing a direct view to an engine through the duct outlet from outside the engine room.
