Abstract: An exhaust system support structure is provided with a vehicle body bracket, a vibration insulating member and an exhaust bracket. The vehicle body bracket has a base part that is coupled to a vehicle body member, and a pair of support parts extending from the base part. The vibration insulating member is coupled between the support parts. The exhaust bracket has a first end coupled to the vibration insulating member and a second end coupled to an exhaust system member. The vibration insulating member includes a housing part that houses the first end of the exhaust bracket. The support parts can be linked together with a linking part. Vibrational displacement of the vibration insulating member is suppressed by a regulating body protruding from the vehicle body bracket side of the vibration insulating member and a regulating body protruding from the linking part side of the vibration insulating member.
