Abstract
A supercharging apparatus for an internal combustion engine wherein a supercharger is disposed in the intake passage of the engine. A stepwise variable transmission drives the supercharger. The transmission has a plurality of gear stages so that the rotational characteristics of supercharger can be changed. The stepwise variable transmission has a one-way clutch that interrupts the driving relation between a lower gear stage and the engine output shaft during shift-up operation. Therefore, rapid shift-up operation and shockless shift-down operation are obtained.
