Abstract
An electrical base 32 having a stationary detection element 31 is fixed to a body case 11 movably supporting a spindle 13, and a synthetic resin made scale holder 34 is provided to synchronize with the spindle 13 and move through a guide 33. In addition, a scale 36 having a movable detection element 35 is adherently fixed to the scale holder 34 at a plurality of points. More specifically, a projection 51 is fixed through an adhesive layer 52 to the back face of the scale 36, and held in a accommodating hole 46 formed in the scale holder 34, and then adhered through an adhesive layer 53 in the circumferential direction. As a result, the reduction in weight can be achieved and a disadvantage with the reduction in weight (which is that a gap between a stationary detection element and a movable detection element is changed) can be resolved.
