Abstract:
1. An automobile rear structure comprising: a rear-side arranged member which is arranged on a vehicle-body rear side of a muffler and is configured to interfere with exhaust gas discharged from the muffler so as to make a portion of the exhaust gas flow downwardly; and a flow rectification member which is arranged below the muffler and guides the downwardly flowing exhaust gas in the direction along an air flow flowing below the floor of the vehicle body to merge the downwardly flowing exhaust gas into the air flow, wherein the rear-side arranged member includes a diffuser which is formed in substantially a cylindrical shape and which houses a muffler pipe of the muffler inside an opening portion on a front-end side of the diffuser, and which discharges the exhaust gas discharged from the muffler pipe from an opening end portion of a rear-end side of the diffuser, the portion of the exhaust gas is discharged downwardly from a space defined between a front end portion of the diffuser and a body portion of the muffler, and the flow rectification member is formed by a lower portion of the front end portion of the diffuser being folded toward a radial inside.
