Exhaust gas purifying device for engine

摘要

To provide an exhaust gas purifying device for a straddle-type vehicle capable of avoiding a poor appearance when a secondary air supply pipe is connected to an exhaust pipe. An exhaust gas purifying device (20) includes: an exhaust pipe (15) connected to an engine (4); a catalyst located in the exhaust pipe (15); a secondary air supply pipe (23) connected to a portion of the exhaust pipe (15) upstream from the catalyst; and a silencer (30) for accommodating a connected portion (23a) where the exhaust pipe (15) is connected to the secondary air supply pipe (23), and a portion of the exhaust pipe (15) downstream from the connected portion (23a).
