An elastic fixture which is employed for attaching a length measuring apparatus to an object to be measured having a different linear expansion coefficient therefrom. The elastic fixture is elastically deformable in the lengthwise direction of the length measuring apparatus. The elastic fixture includes a sheet-metal curved beam having one end fixedly attached to the length measuring apparatus and the other end fixedly attached to the object to be measured. The sizes and the machining accuracy of the elastic fixture are less restricted, and the elastic fixture can be manufactured easily. In addition, the elastic fixture is applicable to relatively severe temperature environments in a manual machine tool or the like. Further, the sizes and the cost of the elastic fixture can be reduced as compared with a parallel spring mechanism.
