Abstract

Provided is an engine device that facilitates fastening between a main machine frame ( 140 ) and a side surface of an exhaust gas purification case ( 38 ) so that workability of mounting the exhaust gas purification ease ( 38 ) can be easily improved. The engine device is provided with the exhaust gas purification case ( 38 ) for processing exhaust gas from an engine ( 1 ), and the exhaust gas purification ease ( 38 ) is disposed on a main machine ( 120 ) side on which the engine ( 1 ) is mounted. The engine device is provided with the main machine frame ( 140 ) on which the engine ( 1 ) and the like are mounted. The main machine frame ( 140 ) is provided with a bottom support member ( 141 ) for supporting the exhaust gas purification case ( 38 ) and side support devices ( 143, 144 ) for fastening and fixing the exhaust gas purification case ( 38 ) to the main machine frame ( 140 ) in an attachable and detachable manner.

Claims (30)
