1. A sealing structure for a vacuum pump motor, comprising:
a lead wire which passes through an opening formed in a motor frame, wherein the lead wire is configured to be connected to a motor stator; and a seal member which seals the opening, wherein the lead wire comprises core wires and a covering which covers the core wires, wherein a seal is formed around at least part of the core wires inside the covering, and wherein the seal comprises a sealing treatment in which part of the covering is removed to partially integrate intermediate portions of the core wires into a single wire assembly through soldering, the intermediate portions being any portions other than ends of the core wires, and wherein the seal is covered by a heat-shrinkable tube via a sealing medium. |
