Abstract: A fixing structure of a temperature sensor for a vehicle includes: a mounting bracket including one end to support a temperature sensor that senses a temperature of a cooling medium and the other end engaged with an object to be fixed. In particular, a polygonal-shaped coupling portion is formed in the temperature sensor, and a polygonal-shaped fit-coupling groove is formed in the bracket to couple with the polygonal-shaped coupling portion. Accordingly, a layout for mounting the temperature sensor can be improved, while enabling universal applicability to all vehicle types.
