ABSTRACT:
A lock mechanism effectively used for locking, for example, an interrupting handle of an electric interrupter in an OFF position. The lock mechanism includes two plate-like lock piece portions which are juxtaposed to each other substantially in a common plane when effecting the locking, engagement grooves which are formed respectively through the lock piece portions in a direction of a thickness of the lock piece portions, and have respective openings formed respectively in their respective end surfaces which are juxtaposed to each other, and face in the same direction, and a lock ring of a square-loop shape having opposed straight portions to be fitted respectively in the engagement grooves to interconnect the two lock piece portions. When viewed in the direction of the thickness of the lock piece portions, each of the engagement grooves has an L-shape defined by an introduction groove portion and a slide groove portion. A first holding portion and a second holding portion each for holding the straight portion of the lock ring are formed respectively at the introduction groove portion and the slide groove portion of one of the two lock piece portions.
