<p><P>PROBLEM TO BE SOLVED: To reduce the cost and weight by simplifying part management and assembling works in a structure for wirelessly transmitting a signal of a rotation detecting sensor 40 to a controller 36 side. <P>SOLUTION: The rotation detecting sensor 40 is held in a single holder 43 with a processing circuit 44, a transmitting circuit 45 and an antenna 46. The processing circuit 44 rectifys a part of AC signal imposed by the detecting sensor 40 to obtain a direct current necessary for operation of the transmitting circuit 46. The sensor 40, the processing circuit 44, the transmitting circuit 45 and the antenna 46 can be handled as an integrated sensor unit 42, and the above problem can be solved. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
