To improve work efficiency in attachment and suppress attachment errors.
An attachment structure of an engine (1) is for attaching a cam chain (66) that transmits power of a crank shaft (6) to a cam shaft (13) to the crank shaft (6) having a generator (7) installed therein and the cam shaft (13) for opening/closing valves (11, 12). A rotor (72) rotating integrally with the crank shaft (6) is accommodated within a generator cover (5). An indication mark (92) indicating an appropriate position of the crank shaft (6) is stamped on an outer surface (91) of the rotor (72), and an inspection hole (52) enabling visual recognition of the outer surface (91) of the rotor (72) is formed on the generator cover (5). A hollow bolt fixing tool (8) for restricting the rotation of the rotor (72) is attachable/detachable to/from the inspection hole (52).
