<p>PROBLEM TO BE SOLVED: To provide a fitting structure of an insulator capable of easily corresponding to a change in a lamination number of electromagnetic steel plates constituting a stator core.SOLUTION: An insulator 10 includes: a first insulator 11 fitted into a tooth 3 from one end portion of a stator core 1; and a second insulator 12 fitted into the tooth 3 from the other end portion of the stator core 1. Each of the first and second insulators 11 and 12 has claw sections 11b and 12b capable of being fitted into groove portions 4. When each of the insulators 11 and 12 is fitted into the tooth 3, each of the insulators 11 and 12 is inserted into the tooth 3 to a position where the claw sections 11b and 12b are moved beyond protrusion sections 4a while the claw sections 11b and 12b are being fitted into the groove portions 4, and the claw sections 11b and 12b are locked by the protrusion sections 4a with respect to a direction where each of the insulators 11 and 12 is withdrawn from the tooth 3.</p> |
