シヤツターの施錠装置。 In an electric shutter configured to raise and lower the shutter curtain by driving an opening/closing machine based on the operation of a three-point push button: raise, stop, and lower, the drive control circuit of the opening/closing machine has a function in which the shutter curtain is lower than the lower limit position. A lower limit switch is provided, which is always closed when the lower limit position is at the upper limit position, and is switched to the open side when it is detected that the lower limit position has been reached, and a changeover switch that changes in conjunction with the switching operation of the lower limit switch. The circuit is equipped with a locking circuit that closes the shutter curtain lowering circuit in response to switching of the lower limit switch from the open side to the closed side when the switch is stopped. An electric shutter locking device characterized by:
