To provide a rotor magnet inspection device capable of inspecting whether a rotor magnet is fixed or not in a magnet insertion hole.SOLUTION: A rotor magnet 3 inserted into a magnet insertion hole axially penetrating a columnar rotor core 2 extending axially is inspected. A rotor magnet inspection device has: a mounting table 4 having a mounting surface on which the rotor core 2 is mounted; a pressure mechanism having a contact member 6 whose tip is in contact with the rotor magnet 3, and a moving part that moves the contact member 6 toward the mounting table 4; and a load detection unit 7 that detects an axial load received when the contact member of the pressure mechanism presses the rotor magnet 3 axially.SELECTED DRAWING: Figure 12 【課題】磁石挿入孔内でロータ磁石が固定されているか否かを検査可能なロータ磁石検査装置を提供する。【解決手段】軸方向に延びる柱状のロータコア２を軸方向に貫通する磁石挿入孔内に挿入されたロータ磁石３を検査する。ロータ磁石検査装置は、ロータコア２が載置される載置面を有する載置台４と、先端がロータ磁石３に接触する接触部材６と接触部材６を載置台４に向かって移動させる移動部とを有する加圧機構と、加圧機構の接触部材がロータ磁石３を軸方向に押した際に受ける、軸方向の荷重を検出する荷重検出部７と、を有する。【選択図】図１２
