PROBLEM TO BE SOLVED: To provide a lock mechanism with an indicator having an indicator function capable of reliably identifying locking and unlocking of a door and the like.SOLUTION: An operation lever 20 includes: a base end part 56 having a pin hole 53 through which a pin 42 is inserted and a part of its outer peripheral surface facing a display window 18; and an operation part 57 extended from the base end part 56. The operation part 57 is biased by a spring member 64 so that it is positioned above the pin 42, and first and second indicators 17A, 17B are positioned on and arranged along the outer peripheral surface of the base end part 56. The first indicator 17A is exposed in the display window 18 in the state that the operation part 57 is positioned above the pin 42; rotary operation of a key 19 makes a latch plate 16 swing toward a locking/unlocking display device 14; the operation part 57 is pushed down against the spring biasing to move lower than the pin 42 by abutting a tip 16a of the latch plate 16 against the operation part 57 of the operation lever 20 from above; and thus the base end part 56 rotates and the second indicator 17B is exposed in the display window 18. |
