。In the sliding contact device of the present invention, the brushes are made of 3 to 12% by weight of Au, 12% by weight of ptB, and Pd, which are the same as conventional brushes.
33-37% by weight, Ag28-32% by weight, Cu12
The reason why the alloy material is composed of ~16% by weight, Zn Q, and 1~2% by weight is to take advantage of its excellent spring properties.

超えると加工が困難となるものである。In addition, in the composition of the commutator or slip ring material, the reason why 0.5 to 15% by weight of Cd oxide is uniformly and finely dispersed in Ag is to increase the lubricity and improve the wear resistance of Ag. If the amount is less than 0.5% by weight, there is no effect, and if it exceeds 15% by weight, the contact resistance becomes high and unstable. Furthermore, B + S t i G
e, 0.5 to 10 of at least one oxide of T I
The reason why it is uniformly and finely dispersed in weight percent is to increase the softening temperature to suppress adhesion during the rubbing operation and improve wear resistance.If it is less than 0.5 weight percent, the effect is weak, and if it exceeds 10 weight percent. This makes processing difficult.

A slip ring with a diameter of 50 mm was made by punching out the head board. Therefore, a sliding contact device was made by combining these brushes and slip rings, each brush was brought into contact with the slip ring, and the slip/knob ring was rotated in forward and reverse directions to carry out a sliding test under the following test conditions. When the wear amount and contact resistance were measured, the results shown in the right column of the table below were obtained.

100g Near sliding time (blank below) As is clear from the table above, the brushes and slip rings of the sliding contact devices of Examples 1 to 5 are different from the brushes and slip rings of the sliding contact devices of Conventional Examples 1 and 2, respectively. It can be seen that the amount of wear is less and the contact resistance is equally low and stable. This is because the material constituting the slip ring of the sliding contact devices of Examples 1 to 5 has the lubricating effect of Cd oxide and the B
