塵形ロンタラプタ。[Claims for Utility Model Registration] A light emitting element and a light receiving element are disposed opposite to each other with a predetermined gap therebetween, and an optical coupling path formed between the light emitting element and the light receiving element is blocked by a test object. In an interrupter configured to output an object detection signal when a test object is detected, the light emitting element and the light receiving element are housed in respective housing chambers of a casing made of a light-transmitting resin, A flat surface portion is formed on an inner wall facing the light projecting element in the device storage chamber to allow the light emitted from the light projecting element to pass through and proceed along the optical coupling path; a flat surface portion formed on an inner wall facing the light-receiving element in the housing chamber for the light-receiving element so as to cause the light traveling along the optical coupling path to proceed straight to the light-receiving element; 1. A dust-proof type rotor adapter comprising: an inclined surface portion formed to cause light traveling away from the optical coupling path to travel in a direction away from the light receiving element.
