Optical connector cleaning tool

An optical connector cleaning tool comprising:

• a supplier that supplies a cleaning element having a belt shape;
• a cleaning shaft including:
• a head having a pressing surface that presses the cleaning element supplied from the supplier against a connection end surface of an optical connector;
• and
• a supporter supporting the head;
• a collector that collects the cleaning element from the pressing surface;
• and
• a tubular member having an inner hole accommodating the cleaning shaft such that the head protrudes from the inner hole, wherein
• the cleaning element collected from the pressing surface to the collector passes between an inner surface of the inner hole and a first facing portion of the head facing the inner surface,
• the first facing portion includes:
• a first region in which the cleaning element is interposed between the inner surface and the first facing portion;
• and
• a second region adjacent to the first region,
• in a cross section of the optical connector cleaning tool perpendicular to an axial direction of the tubular member, a gap between the inner surface and the first facing portion at the first region is wider than a gap between the inner surface and the first facing portion at the second region,
• the optical connector cleaning tool cleans the connection end surface,
• a portion of the inner surface facing the first facing portion has an arc cross-sectional shape recessed toward an outside of the optical connector cleaning tool, and
• a curvature radius of the arc cross-sectional shape is greater than a maximum width of the inner hole in a thickness direction of the head.
