PROBLEM TO BE SOLVED: To provide an inexpensive sash with a crescent lock, having simple construction for reliably and automatically preventing a locking failure while allowing accurate and easy locking check when outing. SOLUTION: In the sash with the crescent lock 10, when both inside and outside opening/closing bodies are at a normal locking position, a front end 15b of a trigger 15 is protruded from the inside of a lock device body 11 to the outside for abutting on a trigger supporting plate 5 to allow the turning operation of a lever 13 in the locking direction, and when both opening/closing bodies are not at the normal locking position, the front end of the trigger protruded to the outside of the locking device body is moved back into the locking device body by the rocking of a cam plate 19. With the back movement, the cam plate locks a lock disc 16 to prevent the turning operation of the lever in the locking direction. In the locking device body, there are provided a piezoelectric generation mechanism 30 for self-generating power, a transmitter 40 actuated by the piezoelectric generation mechanism to transmit a locking/unlocking check signal, and a locking/unlocking check sensor 50 for controlling locking/unlocking information for the radio signal from the transmitter.
