The invention provides a rotor magnet inspection device. The rotor magnet inspection device inspects a rotor magnet (3) inserted into a magnet insertion hole that axially passes through a columnar rotor core extending in the axial direction. The rotor magnet inspection device includes: a mounting table having a mounting surface on which a rotor core is mounted; a pressing mechanism having a contact member whose tip is in contact with the rotor magnet, and a moving portion that moves the contact member toward the mounting table; and a load detection unit that detects an axial load received by the contact member of the pressing mechanism when the contact member presses the rotor magnet in the axial direction. 本发明提供一种转子磁铁检查装置。转子磁铁检查装置对插入到磁铁插入孔内的转子磁铁(3)进行检查，该磁铁插入孔在轴向上贯通沿轴向延伸的柱状的转子铁芯。转子磁铁检查装置具有：载置台，其具有载置转子铁芯的载置面；加压机构，其具有前端与转子磁铁接触的接触部件和使接触部件朝向载置台移动的移动部；以及负荷检测部，其检测加压机构的接触部件在轴向上按压转子磁铁时受到的轴向负荷。
