Cleaning device of optical connector

An optical connector cleaning device which cleans a connecting terminal surface of a to-be-cleaned object protruding from an optical connector by wiping the connecting terminal surface with a cleaning body, the optical connector cleaning device comprising:

• a main body comprising a feeding mechanism which supplies and wraps up the cleaning body;
• an extending part which extends from the main body;
• and
• a guiding part attached to a tip portion of the extending part, wherein
• the extending part includes an extending tube body and a tip extending part, the tip extending part pressing the cleaning body to the connecting terminal surface;
• the guiding part includes a fitting part, which is fit to a tip portion of the extending tube body, and a tube-shaped guiding body, which is flexible and extends from the fitting part towards an extending direction in which the extending part is extended;
• an insertion hole is formed, into which the to-be-cleaned object is inserted from a tip side of the guiding body, and, into which the tip extending part is inserted from a rear end side of the guiding body;
• the to-be-cleaned object is cleaned by inserting the to-be-cleaned object into the insertion hole of the guiding part attached to the tip portion of the extending part, and by pressing the cleaning body against the connecting terminal surface of the to-be-cleaned object;
• the guiding body comprises a tapering tube part, a thickness of which decreases while the tapering tube part extends towards the extending direction, and a tip tube part, which has a substantially uniform thickness and extends from a tip of the tapering tube part towards the extending direction;
• and
• the substantially uniform thickness of the tip tube part is smaller than or equal to a minimum thickness of the tapering tube part.
