Abstract
An exhaust heat recovery device includes: a first flow path member; a second flow path member adjacent to the first flow path member, and which includes a heat exchange unit configured to perform heat exchange between exhaust gas flowing in the second flow path and a refrigerant; a valve mechanism configured to switch between opening and closing of the first flow path and the second flow path; and a drive unit which includes a drive shaft configured to rotate the rotation shaft portion. The second flow path member is inclined with respect to a flow direction of the exhaust gas in the first flow path, and the drive shaft extends toward the first flow path member and is connected to the rotation shaft portion in a region formed on a lateral side of the second flow path member when viewed in an axial direction of the drive shaft.
