PROBLEM TO BE SOLVED: To provide a lock structure of a cover capable of being mounted and removed easily by a single hand. SOLUTION: The lock structure of the cover is composed of a lock projection 9 and a hinge projection 10 formed on the body, a hinge side fastening part 12 provided on one side of the cover 11 for generating fastening to the hinge projection 10, and a lock fastening part 13 provided on the other side of the cover 11 for generating fastening to the lock projection 9. Thereby the lock fastening part 11 of the cover 11 is engaged with the lock projection 9 by engaging the hinge side fastening part 12 to the hinge projection 10 when the cover 11 is mounted and by rotating round the hinge projection 10. When thereafter the cover 11 is removed, unlocking is made while the hinge side fastening part 12 is maintained in the fastened condition to the hinge projection 10, and the cover 11 is opened centering on the hinge projection 10.
