Zusammenfassung:	To suppress deterioration of performance due to occurrence of burrs in a weight roller.SOLUTION: A weight roller 1 comprises: a cylindrical weight adjusting member 3; and a covering member 5 covering at least a part of the bottom surface and the outer peripheral surface of the weight adjusting member 3, and projecting to the upper surface side and the bottom surface side of the weight adjusting member 3. The covering member 5 is made of a resin composition, and the covering member 5 is formed so as to avoid a divided part of a mold from being arranged on the extreme end surfaces on the upper surface side and the bottom surface side.SELECTED DRAWING: Figure 1 【課題】ウエイトローラーについて、バリの発生による性能低下を抑制する。【解決手段】ウエイトローラー１は、円筒状３の重量調整部材と、重量調整部材３の少なくとも底面の一部及び外周面を被覆すると共に、重量調整部材３の上面側及び底面側に突出した被覆部材５とを備える。被覆部材５は樹脂組成物からなり、被覆部材５は、上面側及び底面側の最端面に金型の分割部が配置されるのを避けて形成されている。【選択図】図１
