PROBLEM TO BE SOLVED: To provide an epoch-making brake system capable of simply and effectively controlling rotation speed of a frictional body while the frictional body is rotated in proportion to rotation of a rotary body.;SOLUTION: In a brake system reducing rotation speed of the rotary body, the brake system comprises a first rotary body 2 rotated by a rotary shaft 6, and a second rotary body 3 capable of keeping in contact with the first rotary body 2 and rotating at rotation speed different from that of the first rotary body 2. The second rotary body 3 is connected with the rotary shaft 6 of the first rotary body 2. Rotation speed of the rotary shaft 6 of the first rotary body 2 is reduced by reducing rotation speed of the first rotary body 2 or second rotary body 3 by means of contact between the second rotary body 3 and first rotary body 2, and the rotation speed of the first rotary body 2 and first rotary body 3 is also reduced.;COPYRIGHT: (C)2003,JPO
