た。Conventional technology Normally, a guide bar is constructed by sandwiching an intermediate plate between left and right outer plates and adhering these plates together by brazing, spot welding, etc. A part of the material is removed by punching etc. in the part of the outer plate or middle plate, for example, the central part where the load is relatively low, and the lightening part such as plastic is filled in the part. Known is a lightweight guide bar. In such a conventional lightweight guide bar, the filler is easily peeled or dropped from the outer plate during use, and the tree branch or the like is caught in the recessed portion caused by this, which not only hinders the work but also the appearance design. In addition, if the lightening portion formed by a band-shaped cutout of a predetermined width such as alphabetic characters formed in the overlapping portion of the left and right outer plates is asymmetrical, the filling material for each lightening portion Filling must be performed in the filling process using separate filling gates, the work is complicated, and the filling material is difficult to be completely filled in every corner of the lightening portion.
