Abstract
A locking device comprises: a locking case that is attached to a cover of a cabinet; a locking bolt that is disposed in the locking case and is movable in the forward and backward directions; a spring that urges the locking bolt in such a way that the locking bolt protrudes from the inside of the locking case and thereby locks the cover in such a way that the cover cannot be separated from the main body of the cabinet; and a key that includes a cam for displacing the locking bolt from a locking position to an unlocking position against the urging force of the spring. The locking case is attached in such a way that the locking case is exposed at the outer surface of the cover. The key comprises a shaft part that is above and below the cam and is rotatably held in a support hole formed in the upper and lower walls of the locking case, and the key is therefore supported by the locking device instead of being supported by the cover of the cabinet.
