To provide a shear pin realizing a long life by suppressing deterioration.SOLUTION: A generally columnar shear pin 1 has a function of fixing members 4a and 4b by being inserted in through-holes 5 formed on the adjacent two members 4a and 4b, and a function of breaking when receiving predetermined shear force to release the fixing of the two member 4a and 4b. The shear pin is equipped with an inside pin 2 having a predetermined shear strength, and a generally cylindrical outer cylinder 3 that has a cavity 3b in which the inside pin 2 is inserted.SELECTED DRAWING: Figure 3

【課題】劣化を抑制することで長寿命化を実現したせん断ピンを提供する。【解決手段】隣接する二つの部材４ａ、４ｂに形成された貫通孔５に挿入されて部材４ａ、４ｂを固定する機能と、所定のせん断力を受けたときに破断して二つの部材４ａ、４ｂの固定を解除する機能とを有する略円柱形状のせん断ピン１において、予め設定されるせん断強さを有する内側ピン２と、この内側ピン２が挿入される空洞３ｂを有する略円筒形状の外筒３とを備える。【選択図】図３
