Abstract
An exhaust gas purification device capable of enhancing handling operability such as maintenance of an engine includes two gas purification bodies which purify exhaust gas discharged from the engine, inner cases in which the gas purification bodies are incorporated, and outer cases in which the inner cases are incorporated. The outer cases are arranged side by side in a moving direction of exhaust gas and connected to each other. One of the adjoining inner cases is inserted into the other inner case to form a double-layer structure. A loosely-fitting gap is formed between an inner side surface of the one inner case and an outer side surface of the other inner case.

An exhaust gas purification device comprising two gas purification bodies for purifying exhaust gas discharged from an engine, inner cases for incorporating the gas purification bodies, outer cases for incorporating the inner cases, the outer cases being arranged side by side in an exhaust gas moving direction and connected to each other,
- one of the adjoining inner cases is inserted into the other inner case to form a double-layer structure, and a loosely-fitting gap is formed between an inner side surface of the one inner case and an outer side surface of the other inner case.
An exhaust gas purification device comprising an upstream side gas purification body for purifying exhaust gas discharged from an engine, a downstream side gas purification body for purifying exhaust gas discharged from the engine, an upstream side gas purification body case for incorporating the upstream side gas purification body, a downstream side gas purification body case for incorporating the downstream side gas purification body, and a gas discharge side of the upstream side gas purification body case and a gas intake side of the downstream side gas purification body case being fitted and connected to each other,
- the upstream side gas purification body case and the downstream side gas purification body case are formed into cylindrical shapes in which exhaust gas intake sides and exhaust gas discharge sides of both the gas purification body cases have the same diameters, and a diameter of one of the upstream side gas purification body case and the downstream side gas purification body case is smaller than that of the other one.
