Abstract
A construction machine is capable of reducing a decrease in work efficiency due to maintenance for capturing dust. The construction machine includes: an engine; a heat exchanger; a cooling fan that sucks air into an engine chamber to pass the air through the heat exchanger; an intake chamber independent of the engine chamber; an intake tube connected to the intake chamber; and a dust receiving part. The intake tube has a curved part, which has an outside inner wall surface allowing dust in the air to contact it. The dust receiving part is located downstream of the outside inner wall surface to be capable of receiving dust.
