Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an operation detecting device which can surely detect the operation of a sprinkler fire extinguishing device even when an abnormality takes place on the device itself, and also, can prevent a wrong operation of an alarming device or the like connected to a switch from occurring. SOLUTION: This operation detecting device 1 is equipped with and constituted of an input means 3 which performs an advancing/retracting motion in response to a change of the pressure of fire extinguishing water when this sprinkler fire extinguishing device is operated, an output means 4 which performs an advancing/retracting motion in response to the motion of the input means 3, a delay means 5 which is provided between the input means 3 and the output means 4, and can delay the retracting motion of the input means 3, and a switch which can be on-off-switched by the advancing/retracting motion of the output means 4.
