図4は、図3のE部の拡大図である。
この溝部22dは、大径部22bの軸方向のほぼ全域にわたって形成されている。また、溝部22dの深さは、突起21bの高さHと同等あるいは突起21bの高さHよりもわずかに大きく形成され、溝部22dの幅は、突起21bの幅Wと同等あるいは突起21bの幅Wよりもわずかに大きく形成されている。
以上説明したように、本形態では、ゴム輪21の内周面21aに複数の突起21bが形成され、芯部材22の外周面22aに突起21bに係合する複数の溝部22dが形成されている。そのため、突起21bと溝部22dとによって、ゴム輪21と芯部材22との間の滑りを防止することができる。したがって、本形態では、ゴム輪21と芯部材22とを接着するための接着工程が不要となり、搬送ローラ4の組立が容易になる。
上述した形態は、本発明の好適な形態の一例ではあるが、これに限定されるものではなく本発明の要旨を変更しない範囲において種々変形実施が可能である。
