ABSTRACT:
A clutch mechanism easy to manufacture, high in assembling precision, and simple and inexpensive in structure, in a automatic takeup coat film transfer tool. A tape core on which a coat film transfer tape is wound is held and supported from both sides in the axial direction by a payout rotary gear and a rewind button, and the tape core and payout rotary gear are frictionally engaged with each other in the rotating direction by force transmitting means making use of frictional force by thrust load. This power transmitting means is composed of plural engaging protrusions elastically deformable in the axial direction, provided integrally to the payout rotary gear, and these engaging protrusions are elastically engaged with the axial end of the tape core by a specified pressing force, by the axial engaging force of the payout rotary gear and rewind button.
