PROBLEM TO BE SOLVED: To meet demand for a supporting device for stator cores so constructed that its structure is simplified and both rigid structure and flexible structure can be simultaneously achieved. SOLUTION: A core supporting member 4 is constructed of: multiple key bars 41 and spring members 42. The key bars 41 have fitting protruded streaks 411 respectively fit into multiple fitting grooves 31 formed on the outer circumferential portion of a stator core 3. Each of the spring members 42 in a U shape has attachment legs 421, 422 at both ends and is provided at its intermediate portion with snapping force so that it functions as a spring plate portion 423. The spring members are fixed on the surfaces of the key bars 41 on the opposite side to the fitting protruded streaks 411 at appropriate intervals in the direction of the length. The attachment legs 421, 422 formed at both ends of the U-shaped spring members 42 are fixed on the shelf plates 21 of a stator frame 2 by bolts 425, 426. COPYRIGHT: (C)2007,JPO&INPIT
