けられる。The roller boss 7 consists of a block 3 shown in FIGS. 5 and 6, and a block 4 shown in FIGS. 7 and 8,
It has an overall drum shape. Block 3 and Block 4
Both have a conical shape and are provided on the rotating shaft 2 facing each other.
ブロック３は、中心に回転軸２を通し、その周りに軸方
向に沿って四本の溝３ａを設けである。The block 3 has the rotating shaft 2 passed through its center, and four grooves 3a are provided around it along the axial direction.
また、ブロック３は回転軸２に対し、回転方向にも軸方
向にも固定して取付けである。Further, the block 3 is fixedly attached to the rotating shaft 2 both in the rotational direction and in the axial direction.

面側は、若干の厚みを有し、外周に溝６を設けである。The block 4 has substantially the same shape as the block 3, and is provided with a groove 4a around the rotating shaft 2. Further, the block 4 is mounted with the ability to move in the axial direction with respect to the rotating shaft 2. This allows the blocks 3 and 4 to fit the tips of their companions into the grooves 3aBL and 4a, restrict movement in the rotational direction while allowing the block 4 to move in the axial direction, and prevent the block from moving as a whole. It is shaped like a drum. Further, the bottom side of the block 4 has a slight thickness, and a groove 6 is provided on the outer periphery.

The lever 5 is rotatably supported near the rotating shaft 2, and its operation is controlled by a motor or the like. This moves the block 4 and changes the minimum radius of the roller boss 7.
に記ゴムローラ１は、円筒形状を有し、第２図及び第３
図に示すように５０−ラボス７の形状に合わせて内側中
央を凸とした断面形状を有する。The rubber roller 1 shown in FIGS. 2 and 3 has a cylindrical shape.
As shown in the figure, it has a cross-sectional shape with the inner center convex in accordance with the shape of the 50-Labos 7.
これによって、ゴムローラ１はローラボス７に対して確
実な位置決めがなされる。Thereby, the rubber roller 1 is reliably positioned relative to the roller boss 7.
次に１本実施例の外径可変ローラの作用について説明す

の外側表面の走行速度を変えることができる。As a result, the drum shape of the roller boss 7 is shrunk in the lateral direction, and the minimum radius increases as shown in FIG. Since the shape matches the shape of the roller boss 7, the outer diameter can be changed without causing lateral displacement or the like. In addition, by changing the outer diameter of the rubber roller l, it is possible to
The running speed of the outer surface of the can be varied.
