状態にならないように慎重に扱う不便さがあった。In such a conventional fixture, it is very difficult to remove the electric device from the DIN rail, or even if the difficulty is eliminated, the portion that has elasticity is complicated. However, its design is also complicated, and the width in the direction along the DIN rail is large due to the complicated mechanism, so it is suitable for small-sized, particularly thin electric devices with a small width in the direction along the DIN rail. It is difficult to apply, and when the electric device body 1 is attached to the DIN rail 3, the protrusion of the elastic piece does not get over the protrusion of the protrusion and the electric device 1 is not easily detached from the DIN rail 3. There was an inconvenience to handle carefully.
