As a result, it is possible to prevent the moving portion 3 from coming to a standstill due to the balance of magnetic forces (it is possible to prevent the balance of magnetic forces from acting as a brake on the moving portion 3), and it is possible to ensure smooth movement of the moving portion 3.

  • the types of positional relationships between the multiple arc-shaped second magnets 65 and the multiple arc-shaped third magnets 66 based on this positional relationship include the "overlapping positional relationship" shown in Figure 8(a), the “non-overlapping positional relationship” shown in Figure 8(b), and the “spaced positional relationship” shown in Figure 8(c).
  • Figure 8(a) shows an "overlapping positional relationship" in which the downstream end of the arc-shaped second magnet 65 overlaps with the upstream end of the downstream arc-shaped third magnet 66 of adjacent arc-shaped third magnets 66, 66, and the upstream end of the arc-shaped second magnet 65 overlaps with the downstream end of the upstream arc-shaped third magnet 66 of adjacent arc-shaped third magnets 66, 66.
  • Figure 8(b) also shows a "non-overlapping positional relationship" in which the rear end surface of the downstream arc-shaped third magnet 66 and the front end surface of the arc-shaped second magnet 65 are in surface contact when viewed from the vertical direction, and the front end surface of the upstream arc-shaped third magnet 66 and the rear end surface of the arc-shaped second magnet 65 are in surface contact when viewed from the vertical direction.

  • This variation 1 of the second embodiment also provides the same effects as the second embodiment.
  • the positional relationship between the plate-shaped second magnet 15 and the plate-shaped third magnet 17 is the "overlapping positional relationship" described above.

Therefore, the moving part 3 is pushed in the direction of arrow A where its movement is restricted, and can move more strongly in the direction of arrow A.
  • Increasing the magnetic force at the downstream ends of the second plate-shaped magnet 15 and the third plate-shaped magnet 17 is not limited to providing the first additional magnet 71, second additional magnet 73, third additional magnet 75, and fourth additional magnet 77 shown in FIG. 9(a).

  • the thickness of the upstream end of the plate-shaped first magnet 9 may be made greater than the thickness of its downstream end (by making it tapered), thereby strengthening the magnetic force of the upstream end of the plate-shaped first magnet 9.
