Abstract
A regeneration device () executes regeneration treatment of a filter () in an exhaust gas purifying device () by burning particulate matter trapped in the filter (). The regeneration device () interrupts the regeneration treatment of the filter () when an exhaust gas temperature T detected by an exhaust gas temperature sensor () becomes less than an exhaust gas temperature threshold Tt during a period of performing the regeneration treatment of the filter (). In a case where the regeneration treatment of the filter () is interrupted, when the exhaust gas temperature T becomes equal to or more than the exhaust gas temperature threshold Tt, the regeneration treatment of the filter () is restarted.
