CIRCUIT BREAKER FOR BRUSH HOLDER

摘要

A circuit breaker mounting section is provided for mounting a circuit breaker to a brush holder assembly in an electric motor. The mounting section is partitioned and formed so as to surround three sides of a circuit breaker with a partition wall projecting from the base plate of the brush holder assembly in a direction parallel to the axis of a motor core projecting through the assembly such that the outer surface side of the circuit breaker mounting section is open. The outer surface side opening of the breaker mounting section is surrounded and sealed by an inner side surface of a frame when the brush holder assembly is fitted and mounted in the frame.
