A noise reduction structure for a turbocharger is provided to form the noise reduction structure integrally with the turbocharger and to couple an intercooler to a hose smoothly. A noise reduction structure for a turbocharger includes a pipe(30), a plurality of fixing bead parts(32,34), and an axial pipe(36). The pipe is connected to the turbocharger. The fixing bead parts are formed inward on a circumferential surface of one end of the pipe at predetermined intervals. The axial pipe is formed between the fixing bead parts to form a noise reduction section. The noise reduction section has an inner diameter smaller than that of the pipe. The axial pipe has at least one through-hole connected to the outside. When the noise reduction section of the pipe is inserted into the hose connected to the intercooler, an outer periphery of the pipe tightly contacts an inner periphery of the hose of the intercooler.
