<P>PROBLEM TO BE SOLVED: To solve the problem that an exclusive space is required for the attachment of an encoder in the case of independently attaching the encoder, and the encoder ends up with an exclusive encoder and the versatility of the encoder device is not achievable in the case of (integrally) including the encoder in a clutch and a bearing. <P>SOLUTION: There is provided an encoder device for easily mounting a magnet to the outer periphery of a clutch driving wheel. The outer periphery of the crutch driving wheel is used, and a flexible magnet having the mutual polarities of N pole and S pole is arranged so as to be annularly rounded by a predetermined pitch at the portion so that an encoder can be attached without changing any existing clutch. Also, the flexible magnet is used so that the encoder can be attached regardless of the outer diameter of the clutch, and a magnetic detection device part is commonly used so that inexpensive and wide application can be achieved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
