Abstract:
An exhaust heat recovery unit that includes: a lead-in pipe that leads a heat medium from outside an exhaust pipe, via an inlet portion of an heat exchanger, into the heat exchanger; a lead-out pipe that leads the heat medium out from the heat exchanger, via an outlet portion of the heat exchanger, outside the exhaust pipe; and a pair of seal members that seal a space between the inlet portion and the lead-in pipe and a space between the outlet portion and the lead-out pipe, with at least one of the pair of seal members including an O-ring disposed in a position in which the at least one of the pair of seal members does not contact exhaust gas flowing through the exhaust pipe and in which the at least one of the pair of seal members contacts the heat medium.

Claim (Index 1):
An exhaust heat recovery unit comprising:\n a heat exchanger provided inside an exhaust pipe through which exhaust gas flows, the heat exchanger exchanging heat between the exhaust gas and a heat medium; a pair of open portions that include an inlet portion and an outlet portion, the inlet portion being formed in the heat exchanger and being configured to lead the heat medium into the heat exchanger, and the outlet portion being formed in the heat exchanger and being configured to lead the heat medium out from the heat exchanger; a lead-in pipe that is connected to the inlet portion and leads the heat medium from outside the exhaust pipe, via the inlet portion, into the heat exchanger; a lead-out pipe that is connected to the outlet portion and leads the heat medium out from the heat exchanger, via the outlet portion, outside the exhaust pipe; and a pair of seal members that seal a space between the inlet portion and the lead-in pipe and a space between the outlet portion and the lead-out pipe, with at least one of the pair of seal members including an O-ring disposed in a position in which the at least one of the pair of seal members does not contact the exhaust gas flowing through the exhaust pipe and in which the at least one of the pair of seal members contacts the heat medium.
