OVERLOAD PROTECTING MECHANISM AND ITS ASSEMBLING METHOD

摘要

PROBLEM TO BE SOLVED: To reduce a size and costs of an overload protecting mechanism. SOLUTION: A cam 17 having recesses with a constant pitch is formed on inner diameter surface of an outer wheel 2 concentrically engaged with an inner wheel 1. A rolling element 3 is interposed between the cam 17 and the corresponding inner wheel 1. A C-type spring 4 is used as an elastic member for energizing the rolling element 3 for the cam 17.
