PROBLEM TO BE SOLVED: To enable an index to be adjusted by a simple operation with a low- cost structure by only making use of the deflection of a lead terminal of a flux-detecting element. SOLUTION: An index-signal output unit is the one that conducts a moving adjustment of the flux-detecting element 7 in the tangential direction of the external periphery of a rotor yoke 3 so that the phase difference between the index signal detected by the flux-detecting element 7 and an index reference signal previously stored on a floppy disc is in the range of the specification. A lead terminal 7a of the flux-detecting element 7 is connected to a detected- signal output terminal on a print-circuit substrate 2 and, by the deflection of the lead terminal 7a by a tool, the moving adjustment in the tangential direction of the flux-detecting element 7 is conducted. |
