COMMUTATOR MOTOR

摘要

PURPOSE:To prevent generation of cracking and breaking of a brush due to an external force and others by having said brush built-in in a brush holder by means of a protrusion provided in the brush and a detent provided in the brush holder without allowing the brush to project into said holder. CONSTITUTION:A brush 22 is prevented from projecting from a brush holder 23 by means of a protrusion 22a provided in the brush 22 and a detent 23b provided in the brush holder 23 in the manner of corresponding to said protrusion. When the brush 22 is built-in in a motor, a power breaking the protrusion 22a is applied from an anti-commutator side of the brush holder 23. Therefore, the brush 22 is energized by a spring 24 interposed within the brush holder 23 to project from said holder 23.
