To provide a fish gripper movable smoothly by reducing slide resistance, while securing strength.SOLUTION: A fish gripper for gripping a fish mouth, includes a movable part moving along a prescribed movable plane, and a stationary portion for supporting the movable part. The stationary portion includes an inner part made of a resin for constituting a part where the movable part is slid, and an outer part positioned outside the inner part, and comprising a material having higher rigidity than the inner part, and the outer part includes a first outside member 18 and a second outside member as a tabular plate part.SELECTED DRAWING: Figure 1【課題】強度を確保しつつ摺動抵抗を低減してしてスムーズな動きを得ることができる魚掴み器を提供する。【解決手段】魚の口を掴むための魚掴み器であって、所定の可動平面に沿って移動する可動部と、該可動部を支持する固定部とを備え、固定部は、可動部が摺動する部分を構成する樹脂製のインナー部と、該インナー部の外側に位置し、インナー部よりも高剛性の材質からなるアウター部とを備え、アウター部は、板状のプレート部としての第一外側部材１８と第二外側部材とを備えている。【選択図】図１
