Abstract
A circuit breaker has a metal frame (10) disposed on a base of a housing. A trip-bar (6) made of molded plastic of like material is rotatably held on the frame (10) by insertion of a trip-bar pin (15) into a center through-hole provided on the trip-bar, and pinchers (14,14) of the trip-bar (6) pinch the trip-bar pin by elasticity of the plastic material to hold the same in place with very little lateral play.
