Abstract: A winding device for winding measuring tape, which allows a user to fix the top end of a measuring tape drawn by a desired length from a housing without applying a load to the tape and to easily release the tape from the fixed condition. A winding reel comprises a winding reel body including a winding spring for winding a measuring tape and a winding reel cover. The housing is composed of an upper half and a lower half and accommodates therein the winding reel. A recess formed in the reel has an opening in an inner ring of a bearing fitted in a winding reel cover. A recess formed in the housing has an opening in an outer surface of a supporting shaft. When the winding reel slowly rotates in a rewinding direction, a roller prevents the winding reel from rotating by being disposed astride the winding reel-side recess and a winding reel locking portion which is an open end of the winding reel-side recess in a direction of drawing-out of the measuring tape.
