ENGINE SUPERCHARGER

摘要

An impeller (50) for pressurizing an intake air (I) of an engine (E) is provided on a left side end portion (44a) in a supercharger rotary shaft (44) of the supercharger (42). The power from the engine (E) is transmitted to a second sprocket (96), which is provided on a right side end portion (65b) of an input shaft (65) of a speed increaser (54), through a chain (84) to thereby allow the supercharger (42) to drive. The second sprocket (69) is removably fitted to the input shaft (65) by means of a bolt (102). The supercharger rotary shaft (44), the input shaft (65), the second sprocket (96) and the bolt (102) are all accommodated in a supercharger casing (56). The supercharger casing (56) has a right side end face formed with an access opening (105) through which access can be made to the second sprocket (96) and the bolt (102) from an axial direction.
