Claims

[Claims for Utility Model Registration] A shutter blockage abnormality detection device comprising a shutter frame made of a shaped material and a shutter curtain guided and held by the shutter frame, the device comprising: a pressing member that protrudes when a force in the opening direction is applied to the shutter curtain by a detected object; and a pressing member that is housed in a side frame of the shutter frame and that protrudes when the pressing member protrudes. a flexible pipe-like member that is squeezed between the end and the surface of the side frame; and a flexible pipe-like member that is airtightly attached to both ends of the pipe-like member so that the light-emitting part and the light-receiving part thereof face the inner space of the pipe-like member. A shutter blockage abnormality detection device comprising an attached light emitter and a light receiver.
