Abstract: A guidance device includes: a permanent magnet; an accommodating portion; a shielding member configured to shield the magnetic field generated by the permanent magnet; a supporting mechanism configured to support the permanent magnet between a first position and a second position; a driving unit configured to operate the supporting mechanism upon receiving an electric power supply; and a shielding member moving mechanism configured to move the shielding member between a shielding position and a non-shielding position in conjunction with an operation of the supporting mechanism causing the permanent magnet to move in a vertical direction. When the electric power supply to the driving unit stops, the shielding member moving mechanism moves the shielding member to the shielding position in conjunction with an operation of the supporting mechanism causing the permanent magnet to move to the first position.
