Abstract
An exhaust heat recovery device comprises an exhaust pipe, a shell member, a heat exchange portion, a guide portion, and a valve. An exhaust gas downstream end that is a downstream end along the flow path for exhaust gases in the exhaust pipe is disposed in the downstream side of a downstream-side end portion of the heat exchanger along the flow path for exhaust gases in the exhaust pipe. The guide portion comprises a partition wall portion that is a portion from the exhaust gas downstream end in the exhaust pipe to the downstream-side end portion of the heat exchanger in the exhaust pipe, and a guide member disposed so as to at least partially cover a radially outside of the partition wall portion in a manner so as to have an interspace between the partition wall portion and the guide member.
