Abstract
A rotational tape retracting and releasing structure for tape measure is provided which has less rotational wearing and trouble, increased reliability of cooperative rotation, and an easier assembling and disassembling structure. The subject structure for tape measure is characterized in that: a set of planetary gears can be firmly kept inside a gear box and then presented from departing out of the housing, and a sub-rotary disc axis member and a take-up drive can be rotated together.
