Description of the Related Art Conventionally, in order to avoid generation of abnormal noise due to contact between an end winding portion and a seat or between wires, a tube made of a soft synthetic resin cut to an appropriate length is extrapolated from an end of the wire. However, since the frictional force is large, it takes time to perform the operation, and since it is necessary to mount the device with a gap, there is a risk that the device may move or fall off after the device is mounted.
