<p>PURPOSE:To execute and maintain the smooth tilting action of the main body of a circular sawing machine by arranging a compressed spring along the tilting action of the main body of the circular sawing machine at the vicinity of the tilting action supporting point part of the main body of the circular sawing machine to a base side. CONSTITUTION:The rear end part of the base body 14 of the main body 6 of a circular sawing machine is formed in a box state in which the lower part is opened, and a spring receiving part 14a is unitedly hung on the upper wall of the inner surface. A compressed spring 25, energizing the main body 6 of the circular sawing machine in an upward tilting action direction usually, is arranged in the tilting action direction in the box-like inside, and retained with the upper surface of a dish-like receiving member 27 in which one side of the dish-like receiving member 27 is loosely-insertedly supported with the spring receiving part 14a and the other side is supported with a supporting pin 26. When the main body 6 of the circular sawing machine is tiltingly moved manually via an operating handle 23 while the compressed spring 25 is compressed to a base 2 side, the whole is deformedly moved so that the compressed spring 25 is compressed, however since the receiving member 27 is pivotally supported freely tiltably in a flat surface with the supporting pin 26, the whole lower end can be always retained corresponding to the deformed movement of the compressed spring 25.</p> |
