Abstract: A channel cross-sectional area of a lower side channel is set to be smaller than an upper side channel in a predetermined region and greater than the upper side channel on an upstream side and a downstream side of the predetermined region. Accordingly, an ability to drain condensed water is improved by guiding exhaust gas to the lower side channel and facilitating an increase in a flow rate of the exhaust gas guided to the lower side channel. The exhaust gas flowing in the upper side channel and the lower side channel receives flow resistance from a partition member from an extending portion to a front of a main muffler. Thus, the ability to drain the condensed water can be improved with reduction in pressure loss generated in the exhaust gas.

Abstract: An exhaust heat recovery device structure includes: an exhaust pipe; a catalytic converter that is connected to the exhaust pipe; an exhaust heat recovery device that is disposed further toward a vehicle rear side than the catalytic converter, and is disposed at an inner side of a floor tunnel that is formed at a vehicle floor portion, and a water pipe of cooling water is connected to a vehicle transverse direction one side of the exhaust heat recovery device, and the exhaust heat recovery device carries out heat exchange between the cooling water and the gas; and a connecting pipe that, at the inner side of the floor tunnel, connects the catalytic converter and the exhaust heat recovery device, and that is bent or curved toward the vehicle transverse direction one side with respect to a vehicle front side.
