Abstract

To appropriately cool an engine while ensuring the rigidity of a support base that supports an exhaust gas purification device. The engine device (1) includes a cylinder head (2), a support base (121) fixed to the cylinder head (2), and an exhaust gas purification device (100) supported by the support base (121). A cooling air passage (148) through which cooling air from a cooling fan (9) flows is formed between a cylinder head cover (18) on the cylinder head (2) and the support base (121).
