A wireless receiver for an automatically opened or closed door having a fixing structure by an extrusion frame having a hooking step in which the hard fixing state is maintained by an elastic pin having a spring is provided to prevent the movement of the elastic pin having the repulsive force from the extrusion frame. A radio receiver(40) controlling a driving unit of a door forms a first insertion recess(41) and a second insertion recess(42). An insertion part(43) is formed on the one side. It is formed in both sides of fixing protrusions radio receiver extended and formed from the insertion part. An elastic pin(45) is inserted into the fixed projecting part with the spring(48). A grounding part(46) is formed in the elastic pin one end. E ring(47) is inserted into the other end of the elastic pin. The spring inserted into the elastic pin is positioned between a floor surface of the insertion part and ground upper surface. The elastic pin flexibly flows elastic deformation rang of the spring from the fixed projecting part.
