cultivators of this invention is to ride in the beacon and rearview mirrors and roof of the upper part of the installation as in one of the coupler because it can be installed using a beacon and rearview mirrors and roof, as well as usability is expected to improve the assembly performance and ease-of-use, it can be installed on board of the cultivators combines both beacon and rearview mirrors and roof by one of the coupler as well as the upper part is to help produce clean and streamlined to prevent from becoming a mess, and to provide a beacon and rearview mirrors and roof of the tiller coupler that can significantly reduce the costs associated with installing a flashing light in the rearview mirror and roof tiller. To this end, the present invention is to form bent in L shaped surface, the flashing lights and the engaging portion 111 of the pipe-shaped and is provided with the rear side of the rear-view mirror type pipe coupling part 112 is provided with a first coupler (11), is located at the rear side of the first coupler (11) entered into by the first coupler 11 and the bolt (B) and is provided with a frame coupling portion 121 of the pipe-in back to the L type bending is made of a second coupler is formed to obtain a bond (12) (10), the coupler is coupled to the flashing light coupling section 111 provided on one side a first coupler 11 of 10, which is fixed Beacon (20) The coupling port 10 of the first coupler (11) rear-view mirror is to be fixed to the rearview mirror coupling portion 112 provided on the back surface (30) and A second coupler of the coupler (10) (12) fixedly coupled to frame coupling portions 121 provided on the back of the roof is made of tiller 41 includes a roof frame (40) is fixed. Frame coupling portion 121 of the warning light coupling portion 111 and the rear-view mirror coupling portion 112 and the second engagement port 12 of the first coupler (11) constituting the coupling port 10 is circular, consists of a tubular body having a
