PROBLEM TO BE SOLVED: To provide a fitting structure of a tachometer sensor enabling to easily and quickly exchange or check a tachometer sensor. SOLUTION: This fitting structure 30 of a tachometer sensor is used for an exhaust turbine supercharger 1 comprising a compressor impeller 8 for sending an air 2 outside in the radial direction with rotary drive thereof, a compressor part 3 comprising an air guide casing 24 arranged so as to surround the outside of the compressor impeller 8 in the radial direction, and a muffler 10 provided upstream of the compressor part 3 so as to reduce the suction noise of the air 2 flowing into the compressor part 3. A pipe 14, which comprises a tachometer sensor 16 for detecting the number of revolution of the compressor impeller 8 in a tip thereof, is detachably provided to the muffler 10.
