Exhaust heat recovery device

An exhaust heat recovery device comprising:

• an evaporator evaporating working medium sealed thereinto by exhaust heat from an internal combustion engine;
• a condenser cooling the working medium evaporated at the evaporator, by coolant of the internal combustion engine;
• a communication portion communicating the evaporator with the condenser in an annular shape;
• an internal pressure operating valve being closed when a pressure of the working medium, corresponding to a first temperature of the coolant, is equal to or more than a predetermined pressure;
• and
• a temperature operating valve being closed when a temperature of the coolant is equal to or more than a second temperature higher than the first temperature when the pressure of the working medium is equal to or greater than the predetermined pressure,
• wherein the internal pressure operating valve and the temperature operating valve are disposed between a downstream side of the condenser and an upstream side of the evaporator in the communication portion.
