Abstract

An over load preventing device comprises a driving shaft (2) for driving load sheave, a pressure bearing member (4) fitted outside the driving shaft (2), a driving member (10) for transmitting the driving force from operating means (14) to the driving shaft (2) through the pressure bearing member (4), a rotate-driving member (12) for transmitting the driving force from the operating means (14) to the driving member (10) and having a means for releasing the engagement with driving member (10) when a torque being over the predetermined torque value is applied to the operating means (14), and an elastic member (13) fitted along the axial direction of the driving member between the rear side of rotate-driving member (12) and the inner end of operating means (14). In the conventional art, it cannot but using a pancake spring as a biasing means, so the axial stroke of the biasing means is small, the height of engaging teeth is also made small so as to suit to the stroke of pancake spring, therefore a problem occurs that the variation of load with respect to the height of teeth gets larger.
