摘要： A portable circular saw providing high visibility to a cutting mark line and sufficient operability even in case of an angled cutting. A slant position fixing member upstands from a front side of a base, and a tiltable plate is provided pivotally to the base. A front end of a saw cover is connected to the tiltable plate by a pivot pin. A main body roratably supporting a circular saw blade is pivotally movable by a pivotal movement of the tiltable plate to change inclination of the circular saw blade relative to the base. The tiltable plate is positioned in confrontation with the slant position fixing member, and fastening unit fixes the tiltable plate to the slant position fixing member to maintain a desired inclination of the circular saw blade. The fastening unit includes a thread extending through an arcuate slot formed in the slant position fixing member and engaging the tiltable plate, and a lever fixed to one end of the thread. The lever has a pressure surface in pressure contact with an abutment surface of the slant position fixing member. The abutment surface is in a form of a slant surface.
摘要翻译：便携式圆锯可以提供切割标记线的高可视性，并且即使在成角度切割的情况下也具有足够的可操作性。倾斜位置固定构件从基座的前侧竖起，并且可倾斜的板被枢转地设置到基座。锯盖的前端通过枢轴销与可倾斜板连接。可旋转地支撑圆锯片的主体通过可倾斜板的枢转运动而可枢转地移动，以改变圆锯片相对于基座的倾斜度。可倾斜板被定位成与倾斜位置固定构件对抗，并且紧固单元将可倾斜板固定到倾斜位置固定构件以保持圆锯片的期望倾斜度。紧固单元包括延伸穿过形成在倾斜位置固定构件中的弓形槽并接合可倾斜板的螺纹，以及固定到螺纹的一端的杆。杠杆具有与倾斜位置固定构件的邻接表面压力接触的压力表面。邻接表面是倾斜表面的形式。
