Abstract:
A power transmission device of an engine comprising:an output shaft of a gear-driven transmission unit which is provided in parallel with a crank shaft of the engine and provided with a driving bevel gear at one end thereof, a driving force from the crank shaft being transmitted to the output shaft; a drive shaft placed in a direction orthogonal to the output shaft and provided with a driven bevel gear which meshes with the driving bevel gear; a gear case formed integrally with a crank case for accommodating the gear-driven transmission unit and supporting a shaft situated in a previous stage of the output shaft at both ends of the shaft; a lid member; a first support member; a first shim; a second support member; and a second shim; wherein an opening is formed in the gear case to allow the output shaft to be pulled out of the gear case in a direction from the one end of the output shaft at which the driving bevel gear is provided toward the other end of the output shaft, the lid member is removably attached to the gear case such that it closes the opening, the first support member is removably attached to the gear case for rotatably supporting the output shaft, the first shim is interposed between the first support member and the gear case, the second support member is removably attached to the gear case for rotatably supporting the drive shaft, and the second shim is interposed between the second support member and the gear case.
