Abstract
An optical connector cleaning tool includes a cleaning tool main body, a feed-side bobbin, a cleaning head (cleaning portion), a winding-side bobbin, a moving body that moves at the time of cleaning, a feed mechanism that sends an unused cleaning medium in synchronism with the moving body, and a winding mechanism that drives the winding-side bobbin. The feed mechanism moves a turn-back portion at one point where the cleaning medium is turned back in a direction to separate from the winding-side bobbin. The winding mechanism includes a driving piece that engages with a rotation body of the winding-side bobbin. The driving piece slips with respect to the rotation body when a load to press engaging projections of the rotation body has reached a predetermined load.
