An anti-surge structure for a turbo charger is provided to prevent surge noise from being generated by reducing difference of pressure between a turbo charger of a throttle valve and an intake manifold by opening an auxiliary valve installed at the throttle valve when the throttle valve is closed. An anti-surge structure for a turbo charger comprises a valve hole(10), an auxiliary valve(20) and a spring(30). The valve hole is formed in a throttle valve body(2) that rotates about a rotating shaft(2a) perpendicular to a center shaft. The auxiliary valve is hinged to the valve hole such that the auxiliary valve is opened and closed. The spring has both ends connected with the throttle valve body and the auxiliary valve to apply elastic force to the throttle valve body and the auxiliary valve. The valve hole is formed at both sides of the rotating shaft.
