ABSTRACT:
A casing for a retractable type tape measure includes a coil spring secured to the rule of the tape measure. The casing has an outer shell and a central interior mounting structure for attachment to the inner end of the coil spring. The mounting structure comprises a specially constructed guide post for guiding the inner end of the coil spring in a smooth relatively large radius curve about the mounting structure to the first inner turn of the coil spring, thereby to avoid sharp bends in the spring and permit the use of unannealed spring steel to form the spring.
