To provide an impeller attachment/detachment jig for a magnet pump that allows a worker to simply and safely facilitate attachment/detachment work without touching it directly.SOLUTION: An impeller attachment/detachment jig for a magnetic pump is composed of: a substantially cylindrical base shaft part 11; arm parts 12 to 14 provided radially on an outer peripheral surface of the base shaft part 11 at equal intervals in a circumferential direction; a weight prat 15 located in a direction opposite to a direction in which the arm parts 12 to 14 extend with respect to the base shaft part 11; and a connection part 16 that connects the base shaft part 11 and the weight part 15 to each other. The arm parts 12 to 14 are bent so that their terminal parts face toward a central axis O from three directions with center angles shifted by 120 degrees on the same plane perpendicular to the central axis O of the base shaft part 11. The arm parts 13, 14 have their terminal parts expandable and retractable in a direction away from the central axis O.SELECTED DRAWING: Figure 7 【課題】 作業員がインペラに直接触れることなく簡易かつ安全に脱着作業を行なうことが可能なマグネットポンプのインペラ脱着用治具を提供する。【解決手段】 マグネットポンプのインペラ脱着用治具であって、略円柱状の基軸部１１と、基軸部１１の外周面に周方向に均等な間隔をあけて放射状に設けられた腕部１２～１４と、基軸部１１に関して腕部１２～１４が延びる方向とは反対方向に位置するおもり部１５と、これら基軸部１１及びおもり部１５を互いに接続する連結部１６とから構成されており、腕部１２～１４は、それらの末端部が基軸部１１の中心軸Ｏに垂直な同一面上において中心軸Ｏに向かって１２０度ずつ中心角のずれた３方向から差し向うように曲がっており、腕部１３及び１４はそれらの末端部が中心軸Ｏから離間する方向に伸縮自在になっている。【選択図】 図７
