FIG. 1 is a side sectional view of a mounting portion of a current collector according to the present invention, and FIG. 2 is a view taken in the direction of arrow A in FIG. Reference numeral 2 denotes a case body, as shown in FIG. 2, which has a shape in which a cylinder having a flat bottom surface is cut in parallel with the cylinder axis, as if a tea canister with a lid was cut in parallel with the center axis. The flat plate-shaped lid body 1 provided so as to cover the cross section is formed by using an insulating material. 2a is a side cover of the case body 2. A casing is formed by the case body 2, the side lid 2a, and the lid body 1. A rotating shaft 4 is supported by the case main body 2 and the side cover 2a via bearings 8,8. The connecting wire 7 is installed in the rotating shaft 4, and its end is connected to the collector ring 5, and the collector ring 5 is insulated by the insulating ring 6. The brush 3 formed by bundling a plurality of strands penetrates the lid body 1 and is aligned, and its side surface is in slidable contact with the collector ring 5 in the tangential direction. Incidentally, the contact pressure of the brush 3 with respect to the collector ring 5 can be expressed by the following equation.
