定装置。[Scope of Claim for Utility Model Registration] (1) A brush slidably pressed against a commutator or slip ring of a rotating electric machine, a pressing force detection member that is distorted by the pressing force of this brush, and a brush affixed to this pressing force detection member. a first strain gauge, a frictional force detection member that is distorted by the frictional force between the commutator or slip ring and the brush, a second strain gauge attached to the frictional force detection member, the first and second strain gauges. A brush friction coefficient measuring device that includes a data processing unit that calculates a pressing force and a frictional force from the amount of strain detected in the brush, and calculates a friction coefficient from these values. (2) The pressing force detection member is characterized by being formed of a pair of plates arranged so that the length direction thereof coincides with the direction of the pressing force and the width direction thereof coincides with the direction of the frictional force. A brush friction coefficient measuring device according to claim 1 of the utility model registration claim. (3) The frictional force detection member is formed into an octagonal frame shape by bending a band-shaped plate material in the thickness direction thereof, and is arranged so that the width direction of the plate is perpendicular to the pressing force and the frictional force. A brush friction coefficient measuring device according to claim 1 or 2 of the utility model registration claim.
