ENGINE SUPERCHARGER

摘要

In the present invention, an impeller (50) that pressurizes engine (E) intake air (I) is provided to the left end (44a) of the supercharger rotational shaft (44) of a supercharger (42). Power from the engine (E) is transmitted via a chain (94) to a second sprocket (96) provided to the right end (65b) of the input shaft (65) of a step-up gear (54), and drives the supercharger (42). The second sprocket (96) is removably attached to the input shaft (65) by means of a bolt (102). The supercharger rotational shaft (44), input shaft (65), second sprocket (96), and bolt (102) are housed in a supercharger case (56). An opening (105) for accessing the bolt (102) and second sprocket (96) from the axial center direction is formed at the right end surface of the supercharger case (56).
