孔にこの芯軸を差し込む構成としたものである。2. Description of the Related Art Conventionally, a plastic roller device that has been conventionally used is provided with a plastic roller having a core shaft projecting laterally formed integrally with the roller, and is provided in a hole formed in a metal supporting plate. It is configured to insert the core shaft.
この装置では、荷重をプラスチック製の芯軸で支えるの
で、大きな強度が得にくく、使用に当たり破損を生じや
すい。In this device, since the load is supported by the plastic core shaft, it is difficult to obtain large strength, and the device is likely to be damaged during use.
また、高強度を得るため、プラスチックローラに金属製
の芯軸を差し込み、この芯軸を支持板の孔で支えるよう
にした構成も知られているが、この構成では、芯軸を別
途に設けるので、部品点数が増加し、製造工程も増え、
高コストとなる欠点がある。Further, in order to obtain high strength, a configuration is also known in which a metal core shaft is inserted into a plastic roller and the core shaft is supported by a hole in a support plate, but in this structure, a core shaft is separately provided. Therefore, the number of parts increases, the manufacturing process also increases,
It has the disadvantage of high cost.
そこで、本考案は、高い強度と、従来の芯軸をローラと
一体成形するものと同等の量産性とを両立させるプラス
チックローラ装置を得ることを目的とするものである。Therefore, an object of the present invention is to provide a plastic roller device that achieves both high strength and mass productivity equivalent to the conventional core shaft integrally molded with a roller.

ックローラ装置である。Means for Solving the Problems The present invention is a plastic roller having a core hole, a metal support plate located on the side surface of the roller, and a plastic pipe formed by plastically processing the support plate. A plastic roller device having a tip end inclined and a shape in which a side receiving a load is projected long and having a shaft portion inserted into the core hole to support the roller.
作用 このローラ装置では、荷重を芯穴に差し込まれる金属製

持板を塑性加工するだけであるので、量産性に富み、し
かも先端を傾斜させたパイプ状に形成するので、荷重を
受ける側については十分長いものとすることができる。Action In this roller device, the load is supported by the metal shaft portion inserted into the core hole, and the shaft receiving side is long, so high strength is obtained. Further, since this shaft portion is simply plastically worked on the support plate, it has a high mass productivity and is formed in the shape of a pipe with its tip inclined, so that the side receiving the load can be made sufficiently long.

み立てられる。In this plastic roller device 10, 11 is a plastic roller, which is entirely made of plastic, and core holes 12 and 12 are formed on both side surfaces. Reference numeral 13 denotes a support tool, which is formed by bending a single metal plate, and has central portions rising up in a substantially U-shape from the attachment portions 14 and 14 attached to the usage portions at both ends, and a square hole 15 on the upper surface. Has been formed. Reference numerals 16 and 16 denote support plates, which are side plates at the rising portion of the support tool 14. Reference numerals 17 and 17 denote shaft portions, which are formed by subjecting the support plates 16 and 16 to plastic working so as to have a substantially pipe shape, the tip of which is inclined, and the upper portion of which is longer than that of the lower portion, and which is made to project inward. The shaft portions 17 and 17 are, for example, a support plate 1 in which a pointed tip is a slanted surface and a pointed tip is on the lower side.
It is easily formed by piercing from the outer surface of 6,16. The roller 11 is inserted from below the support tool 14,
Once the support plates 16 and 16 are expanded, insert the shaft into the core holes 12 and 12.
17, 17 are fitted and the upper end portion is projected from the hole 15 to be assembled.

造しうる。As described above, the plastic roller device of the present invention has a core hole formed in the roller, is supported by the metal shaft portion, and the side of the shaft portion that receives the load is long, which is high. Strength is obtained. Further, since this shaft portion is formed only by plastically working the support plate, it is excellent in mass productivity and can be manufactured at low cost. Furthermore, since the tip of this shaft part is inclined, one can be made longer than the structure in which it is simply projected, and since the load is applied to this longer side, the strength is increased. You can Of course, this roller device is composed of only a roller and a support plate, and it is not necessary to separately prepare a metal core shaft, and therefore it can be manufactured at low cost.
