ABSTRACT:
A stator (42) is hooked in a frame body (10) away with a prespecified space from a spindle (2), so that it is not necessary to fix the stator with a screw. The stator (42), therefore, can easily be mounted, and further as it is not necessary to provide a screw hole in the frame body (10), so that the need for waterproofing processing associated with a screw hole is eliminated. Further the stator (42) is hooked in a protrusion (53) of an electronic unit (50) inside the frame body (10) away with a prespecified space from the spindle (2), so that a rotation thereof in the peripheral direction of the spindle due to play and rattle is small and a measurement error can be suppressed.
