PURPOSE:To simplify the construction of a cutting machine and provide a compact cutting machine by locating a guide rod for supporting a travelling housing and providing a travelling guide, in the center of a crankshaft while providing a construction for preventing turning. CONSTITUTION:A housing 4 is supported only by a guide rod 5 so that a slide guide for the bottom surface of the housing is utterly omitted. A square pipe is employed for the guide rod 5 and prevents it from turning. Thus, the travelling housing 4 can be stably supported only by left and right guide rod bearing mount 6 without any aids of supporting mechanism other than the guide rod 5 so that the construction is simplifyed and made compact. |
