<p>An exhaust gas purifying device includes: a case body including a plurality of cases, and heat insulating rings and heat insulators that cover the case body over a substantially-entire area from an upstream side to a downstream side in an exhaust gas flowing direction. The heat insulators are placed inward from joint portions between the cases, and the heat insulating rings are placed in such a manner as to bridge over the joint portions between the cases. With the above arrangement, the surface temperature of the case body can be reliably prevented from becoming high.</p> |
