PROBLEM TO BE SOLVED: To provide a waterproof and dustproof type locking device which makes a key hole closed with a shutter plate during non-operation, allows easy discrimination between states of locking and unlocking when seen from a front side, and has a simple structure.

A first protrusion 17e is formed at least on a surface of the shutter plate 17, and can be fitted into the key hole 16. A pawl fitting 20 is attached in the rear of the turning body 14 and swung by turning the turning body 14, so as to be put into a locked or unlocked state.
