Cord stopper

A cord stopper comprising:

• a socket in which a fitting portion through which a string is to be inserted, is provided;
• and
• a plug configured to press and hold the string inserted into the socket against an inner wall surface of the socket, wherein
• the socket is a cylindrical body surrounded by a pair of surface portions facing each other at a predetermined interval and a pair of side surface portions positioned at respective side edges of the pair of surface portions and facing each other, and which is provided with the fitting portion, one of a pair of opposing opening portions of the cylindrical body is an insertion port into which the plug is to be inserted and attached and through which the string is to be inserted, and another one of the pair of opposing opening portions is an insertion through port through which the string is to be inserted, together with the insertion port,
• each of the surface portions is provided with a slide groove portion whose one end portion communicates with the insertion port and another end portion reaches a position closer to the insertion through port than to the insertion port at an intermediate portion of the surface portion located along a length of the socket in an insertion direction, an inner surface of the surface portion is provided with a guide concave portion whose one end portion is positioned on a side of the insertion through port and extends toward the slide groove portion and another end portion reaches near the another end portion of the slide groove portion, and a portion between the another end portion of the slide groove portion and the another end portion of the guide concave portion is configured to serve as a stopper,
• the plug is provided with a holding portion that protrudes in the insertion direction of the string within the fitting portion, a pair of guide portions that are positioned at a base end portion of the holding portion, intersect a protrusion direction of the holding portion, and protrude toward the pair of surface portions, respectively, and a pair of operation portions that are plate bodies being continuous with tip ends of the guide portions and have surfaces parallel to the protrusion direction of the holding portion,
• when the socket and the plug are assembled, each of the operation portions is positioned inside an outline of the surface portion,
• the plug is provided with a holding convex portion configured to fit and slide in the guide concave portion at a tip end portion of the holding portion opposite to the base end portion, the holding convex portion is slidable between the stopper and the insertion through port along the guide concave portion, and the pair of guide portions are provided to be movable by fitting into the slide groove portion,
• when the plug is moved toward the insertion through port, the string is clamped and fixed between the inner wall surface of the socket and the plug, and
• when the plug is moved away from the insertion through port, a space between the inner wall surface of the socket and the plug is widened, and the string is slidable.
