PROBLEM TO BE SOLVED: To provide a motor rotation detecting mechanism in which a bearing sensor can be removed easily from an end cover. SOLUTION: A bearing sensor 20, where a sensor 21 and a bearing part 22 are unitized, is fitted into a recess 37 formed in an end cover 32 of a motor, and an outer ring 26 of the bearing part 22 is protruded toward further inside of the end cover 32. In a plate member 36, a recess 38 is formed to be mated with a corner 26a of the protruded outer ring 26. According to this constitution, after the plate member 36 is removed, the bearing sensor 20 can be taken out by gripping the extruded outer ring 26, thereby facilitating the operation. |
