<p>PURPOSE:To reduce a gap between the lower surface of a moving body as the secondary side conductor and a progressing magnetic field generating means progressing on the primary side by forming above a branch path, a magnetic body with its flat lower surface into a shape including the carrying path in parallel with a carrying path for dividing the lower surface and providing electromagnets above the moving member. CONSTITUTION:A magnetic body such as a steel plate 9, of which lower surface is flat and in a shape including a divided carrying path, is formed over a branch path, and in parallel with the carrying path, and magnetic force generating means by electromagnets 14 is provided above the moving body 11. When the moving body 11 passes through a branch point, the moving body is floated by the magnetic force. Consequently, since a ball bearing is not necessary between the lower surface of the moving body 11 as the secondary side conductor and a progressing magnetic field generating means 4a progressing on the primary side, a gap between the lower surface of the moving body 11 as the secondary side conductor and the progressing magnetic field generating means 4a progressing on the primary side is thereby reduced.</p> |
