Claims

[Scope of utility model registration request]

A mounting plate that surrounds the outer diameter side of the commutator and is fixed to the fixed part.The sides of the mounting plate, which are attached to this mounting plate and receive the sides of the inclined brush in the thickness direction, are the neutral point under no load. The brush is formed in an X-shape with a center line and spaced apart from each other in the circumferential direction, and the brush is held tilted to one side or the other side with respect to the circumferential direction depending on the direction of rotation. The lower surface is positioned at the neutral point under load depending on the direction of rotation, one end surface in the width direction of the brush is received at the edge, and springs are attached to the upper parts of the outside of both sides. is fitted into the spring catch on the side far from the top of the inclined brush, and presses the brush against the commutator surface, while also pushing the upper half of the brush toward the inclined side. A brush holding device for a DC machine, comprising a spring member that applies a pressing force to an upper half side of a side portion of the cage box.
