Abstract

PURPOSE:To easily replace a transmission wheel in no relation to functional adjustment of a safety clutch, by replaceably providing the transmission wheel, which changes the interlocking ratio of a work device interlocking system, in an outer end part of the safety clutch. CONSTITUTION:A safety clutch 3 is arranged in the side part of a rotary shaft 2 in a case 6, and a metal 21 in the inner side of the left and right paired clutch metals 20, 21 is fitted by a spline to the rotary shaft 2. The metal 20 in the outer side is rotatably provided in the rotary shaft 2, and press holding force between the both metals 20, 21 is adjusted by an adjusting nut 26. Further a transmission wheel 5 is fitted to the clutch metal 20 through an angular hole. By this constitution, the transmission wheel 5, being positioned in an outer end part of the safety clutch 3, can be easily replaced in no relation to functional adjustment of the safety clutch 3.
