Claims (1)

【実用新案登録請求の範囲】[Scope of utility model registration request] 内輪の外周に外輪を同一軸に回動かつ固定可能に嵌め、
内外輪のそれぞれ前面の周方向３等分以上の等分位置に
軸受を回転自在に設け、内輪の各軸受と外輪の各軸受と
を１つづつ対としてその対の軸受間に軸を一方の軸方向
に摺動自在に支持するとともに、各軸を同−輪上の隣接
する軸受からの軸と交差させてその交差内に各軸の一部
分を一辺とする正多角形を形成し、この正多角形の辺を
成す軸部分にローラを挿通し、かつ、各軸受の軸支持点
は段差を設けて各軸の交差点を移動可能として成る間隔
可変クロスガイドローラ。The outer ring is fitted around the outer circumference of the inner ring so that it can rotate and be fixed on the same axis.
Bearings are rotatably provided at positions divided into three or more equal parts in the circumferential direction on the front surface of each of the inner and outer rings, and each bearing on the inner ring and each bearing on the outer ring are paired, and a shaft is placed between the pair of bearings on one side. Each shaft is supported slidably in the axial direction, and each shaft is made to intersect with the shaft from an adjacent bearing on the same wheel to form a regular polygon whose side is a part of each shaft within the intersection. A variable-interval cross guide roller in which the rollers are inserted into the shaft portions forming the sides of a polygon, and the shaft support points of each bearing are provided with steps so that they can move at the intersections of each shaft.
