記載のモータのブラシ構造。[Scope of Claim for Utility Model Registration] 1. In a brush structure of a motor that is in close contact with a commutator and supplies direct current to an armature coil, a brush guide that guides the brush in a direction perpendicular to the rotation axis; a conductive compression coil spring that urges the brush toward the commutator; a spring holding means that holds one end of the conductive compression coil spring and energizes the conductive compression coil spring; and contacts the commutator. a current-carrying part that contacts the brush guide, a positioning part that contacts the brush guide, a spring holding part that holds the other end of the conductive compression coil spring;
A brush structure for a motor, comprising a brush having a coil core forming portion extending inside the coil without touching the conductive compression coil spring. 2. Claim 1, wherein the brush includes a spring holding portion having a circular groove formed around the coil core forming portion, and a coil core forming portion into which an insulator pipe is fitted.
Brush structure of the motor described.
