A clutch mechanism having an easy-to-manufacture and inexpensive constitution, by making use of frictional engaging force in thrust direction, in a coat film transfer tool of automatic winding type. At least at the feed reel side, a clutch mechanism is provided between a driven member of a tape winding portion and a drive side rotary gear for rotating and driving it, and its power transmission makes use of the frictional engaging force in thrust direction between the driven member and drive side rotary gear. This frictional engaging force can be set by properly adjusting the dimensional relation in thrust direction between the mutual constituent members, and therefore the designing and manufacturing conditions of the constituent members are less strict, manufacture is easy, assembling is easy, and hence the manufacturing cost and device cost can be lowered.
