PROBLEM TO BE SOLVED: To provide an exhaust heat recovery device enabling the easy reduction in size while securing necessary heat exchange capacity. SOLUTION: This exhaust heat recovery device comprises a first cylinder 22 connected to a heater 47, a regenerator 46 connected to the heater, and a cooler 45 connected to the regenerator and connected to a second cylinder 32. At least a part of a flow passage for a working fluid cooled by a refrigerant in the cooler is disposed on the outside of a virtual space Vs formed by virtually superimposing the any cross section 32s of a second cylinder perpendicular to the axial direction of the second cylinder on the axis and on the extension of the axis of the second cylinder. By this, the length of the exhaust heat recovery device 10 in the axial direction of the second cylinder can be suppressed. When the cooler is installed on the outer peripheral side of the second cylinder, the outer peripheral part of the second cylinder is effectively cooled. COPYRIGHT: (C)2005,JPO&NCIPI
