各種の潤滑性物質が補給されている。Normally, a pantograph for a train is equipped with two boats, each of which has two rows of sliding plates, spaced apart and replaceable, that come in contact with the overhead contact lines. Various lubricating substances are supplied to the grooves formed between the sliding plates in order to prevent wear of the sliding plates.

用中に折損し脱落する等の欠点があった。Conventionally, grease mixed with graphite has been used as this lubricating substance, but its friction-reducing effect is not sufficient, and
The drawback was that the grease would scatter during driving or be washed away in large quantities by rain. To improve this, a flat plate made of sintered carbon was sandwiched between the sliding plates, but this was too expensive and had the disadvantage of breaking and falling off during use. Ta.

しい。The lubricating piece of the present invention can be obtained by mixing the above-mentioned components by any method, casting, and cooling. For example, in one example, low molecular weight polyethylene wax and petroleum wax are completely melted in a container in an incubator, and then avA4 is added thereto and stirred to completely melt and mix. Further, graphite and molybdenum disulfide are added to this mixture and thoroughly mixed and stirred to prepare a lubricant solution. Next, it is press-fitted into a specified mold, cooled and drained, and removed to obtain a solid lubricating piece. If gully occurs, it is preferable to correct it as appropriate.The obtained solid piece is appropriately cut to a predetermined size, and in some cases, it is also preferable to attach adhesive tape or the like for convenience.
