ル装置。[Claims for Utility Model Registration] Consisting of a scale on which a predetermined scale is formed and attached to a support member, and a detection head that reads the scale, the support member is brought into contact with the abutting reference surface of one of the two members that are relatively displaced. In the scale device, the scale is fixed by abutting the abutment surface of the support member, and the detection head is fixed to the other of the two members, the abutment surface of the support member being formed in an arc shape, A scale device characterized in that the center of the arc is located on an axis obtained by projecting the scale along the abutment reference plane of the one member.
