PROBLEM TO BE SOLVED: To provide a resisting device providing load by a resisting fluid such as an oil during the rotational exercise by human power in various kinds of exercise machines. SOLUTION: The exercise machine is equipped with a body case having a resisting chamber in which the oil is sealed and a rotary resistor 17 supported in the resisting chamber in the body case. A plurality of convex faces 22a having a large radius R22 and a plurality of concave faces 22b having a small radius to with respect a rotary center axis 7a are arranged alternately in a rotary direction X in an outer peripheral face 22 of the rotary resistor 17. A concave 24 making a radius S28 with respect to the rotary center axis 7a large is arranged in an inner peripheral face 23 of the body case when the outer peripheral face 22 of the rotary resistor 17 moves facing the inner peripheral face 23 of the body case as the rotation of the rotary resistor 17 capable of rotating by the human power. A resist adjuster 31 is movably arranged so as to be able to adjust the position of the resist adjuster 31 interposed between the outer peripheral face 22 of the rotary resistor 17 and the inner peripheral concave face 28 of the concave 24 in the rotational direction X in a range between both the ends 28a, 28b of the rotational direction X in the concave 24.
