The device body is fitted to the body so that it is positioned further into the body than the rib, and a C-shaped retaining spring is interposed between the projecting rib and the flange so as to straddle the notch. Since it is attached to the body so that it can rotate freely in a plane approximately parallel to the mounting surface, the structure for connecting the device main body to the body allows the device main body to freely rotate with respect to the body. This also serves as a configuration for Although the configuration allows adjustment of the direction of the detection area,
This has the advantage that the overall configuration can be simplified, and the amount of protrusion of the device body from the mounting surface can be reduced so that it can be installed inconspicuously. In other words, the detection area can be easily changed, the task of adjusting the detection area according to the on-site situation becomes simple, and the detection area adjustment means can be realized with a simple configuration. . In addition, the mirror block is housed inside the device body, and the device body is rotatably fitted into the lower opening of the body, which is fixed to the structure, so the device body can be rotated relative to the body. Even if the detection area is adjusted by adjusting the detection area, the detection direction is hardly visible from the outside, making it particularly effective when used as a human body detection device for crime prevention detection.
