If the contingency occurs when performing the guidance of the capsule medical device, a permanent magnet to provide a guiding device and the like capable of and reliably shield immediately the magnetic field generated. Induction device is provided with a permanent magnet 110, a support mechanism for movably supporting the permanent magnets along the vertical direction, the first position is the lowest position of the movable range of the permanent magnet, the permanent magnet is generated a supporting mechanism for supporting the permanent magnet and a second position induction that is capable of the capsule medical device by the magnetic field, a motor 124 for moving the permanent magnet based on the power supplied from the outside, housing a permanent magnet and capable of accommodating portion 111, a lid 113 and 114 provided in the storage portion, the shielding member movement which moves between a blocking position and a non-shielding position the lid in conjunction with movement in the vertical direction of the permanent magnet and a mechanism, when the power supply to the motor is stopped, the lid portion is moved to the blocking position together with the permanent magnet is moved to the first position.カプセル型医療装置の誘導を行っている際に不測の事態が発生した場合に、永久磁石が発生する磁界を即座に且つ確実に遮蔽することができる誘導装置等を提供する。誘導装置は、永久磁石110と、該永久磁石を鉛直方向に沿って移動可能に支持する支持機構であって、永久磁石の可動範囲の最低位置である第1の位置と、永久磁石が発生する磁界によりカプセル型医療装置の誘導が可能な第2の位置との間で永久磁石を支持する支持機構と、外部から供給される電力に基づいて永久磁石を移動させるモータ124と、永久磁石を収納可能な収納部111と、該収納部に設けられた蓋部113、114と、永久磁石の鉛直方向における移動と連動して蓋部を遮蔽位置と非遮蔽位置との間で移動させる遮蔽部材移動機構とを備え、モータへの電力供給が停止した際に、永久磁石が第1の位置に移動すると共に上記蓋部が遮蔽位置に移動する。
