ABSTRACT:
A tripping torque setting mechanism of an overload clutch having an adjusting nut threadedly engageable with a thread provided on a cylindrical part of a clutch hub, the adjusting nut being tightened against a spring to produce an urging force corresponding to a predetermined tripping torque. A helical line having a pitch coinciding with the pitch of said thread and indicia for indicating the angular positions is provided on one of the adjusting nut or a member which does not rotate relative to the nut, and an indicator is provided on the other. The axially adjacent portions of the helical line are indicated by different colors and the indicia for indicating the angular positions are indicated by the same color as the portion of the helical line to which the indicia correspond. The indicator has a bent portion at one end which is inserted radially outwardly into a hole formed in the clutch pressure plate and has an axially extending portion next to the bent position and held in a gap between the pressure plate and one of the clutch coil springs.
