Beschreibung
Zusammenfassung:	This weight roller (1) is provided with: a cylindrical weight adjusting member (3); and a covering member (5) which covers at least a part of a bottom surface and an outer peripheral surface (7) of the weight adjusting member (3), and which protrudes on an upper surface side and a bottom surface side of the weight adjusting member (3). The covering member (5) is made from a resin composition. Thecovering member (5) is formed while avoiding arrangement of a split portion of a mold at the farthest surface of the upper surface side and the bottom surface side. 配重辊(1)包括圆筒状的重量调节部件(3)、和覆盖部件(5)，该覆盖部件(5)覆盖重量调节部件(3)的至少底面的一部分和外周面(7)，并从重量调节部件(3)的上表面侧和底面侧突出来。覆盖部件(5)由树脂组合物制成，覆盖部件(5)通过具有分割部的模具而形成，并且所述分割部布置在不与覆盖部件(5)的上表面侧和底面侧的最端面相对应的位置处。
