A rotational member comprising:
- a rotational portion rotatably mounted on a support member;
- a pair of arcuate portions provided on a side of said rotational portion closer to said support member to extend from said rotational portion and opposed to each other;
- and
- a hook portion so provided as to extend from a circumferential end of at least one of said pair of arcuate portions in an outward direction intersecting with a mounting direction for said rotational portion for engaging with said support member;
- wherein
- said hook portion is formed with an engaging groove engaging with an engaging portion located outside a mounting hole of said support member, and
