における酸素センサの取付構造。 In an exhaust purification device configured to be able to switch an exhaust gas flow path into a catalyst path provided with a catalyst and an exhaust gas path not provided with a catalyst, the catalyst after the catalyst path and the exhaust gas path are branched. When the exhaust gas flow path is switched to the exhaust gas path side in the space up to the catalyst in the passage, the flow of exhaust gas from the upstream side is not directly directed into the space. 1. A mounting structure for an oxygen sensor in an exhaust gas purification apparatus, characterized in that at least a large part of an oxygen detecting section of the oxygen sensor is formed in the space and substantially faces into the space.
