PURPOSE:To increase attractive force effectively in a magnetically attractive wheel which runs, being attracted to a running surface by magnetization. CONSTITUTION:For example, a magnetically attractive wheel 1 is made a double magnetically attractive wheel which is constituted of a magnetic inner wheel body 2a and a hollow outer wheel body 2b which can move relatively in a orthogonal direction to the axis Z of the inner wheel body 2a, and magnetic fluid 50 is accommodated in the hollow outer wheel body 2b, which is disposed near the ground contact part of the wheel. |
