PROBLEM TO BE SOLVED: To provide an exhaust turbosupercharger in which a noise of a frequency having vane number times as many as the rotational speed is prevented at low costs, with simple structure, and easily. SOLUTION: In order to solve the problem, a suction pipe forming a bend pipe provided at the suction side of the turbosupercharger is provided with a guide vane near a suction pipe outlet at a R part side which is a greater side of the bend pipe of the suction pipe. The guide vane can prevent a velocity distribution caused by a drift current generated with the bend pipe of the suction pipe, and can suppress or prevent the noise of the frequency with the vane number times as many as the rotational speed generated thereby.
