なる。Since the outer frame (5) is configured as described above, it can be easily processed, does not require welding, and the weight can be reduced.
An outer frame (5) is wound around the outer periphery of a motor body (not shown), and a protruding piece (8) at one end (7) has an opening (10) at the other end (9).
, Both ends (7) and (9) are connected, and both ends (7) and (9) are stuck by the tension of the spring steel plate. Thus, the outer frame (5) is formed of a spring steel plate, and one end (7) is provided with the protruding piece (8) and the opening (10) engaged with the protruding piece (8). Since the connection can be performed without using a jig, the motor can be easily and quickly mounted on the outer frame (5) on the outer frame (5), thereby reducing the operation cost and the cost of the motor. Further, the dimensional variation of the outer frame (5) is absorbed by the tension of the spring steel plate, and the accuracy is improved.
