PURPOSE: A cooling structure for a turbine blade of a turbo charger is provided to improve a cooling efficiency of the turbine blade by forming an air layer at an outer wall of the turbine blade, and to make the turbine blade easy to be manufactured. CONSTITUTION: A turbine(3) and a blower(4) are mounted on both sides of a rotating shaft(2) of a turbo charger(1). The rotating shaft(2) is rotatably coupled to a housing(5) by means of a bearing(6). A cooling air feeding path(7) is formed at an inner portion of the rotating shaft(2). One end of the cooling air feeding path(7) is connected with an air intake port(8) through the blower(4) and the other end of the cooling air feeding path(7) is connected with a hollow section(10) formed in a turbine blade(3a). The hollow section(10) is connected with a turbine housing(5a) through a plurality of cooling air discharging hole(11).
