Description

Length adjusting piece for umbilical member Technical Field The present invention relates to an umbilical length adjuster. Background As an umbilical member used for clothing and the like, for example, a shoelace is used, but the length of the shoelace has been adjusted by a special knotting method such as tying a bow. However, such a special knot tying method has problems that it is impossible for a child to perform an adjustment with one hand, and it is difficult to perform an adjustment while wearing gloves. As a means for solving this problem, patent document 1 discloses a rope comprising a tubular rope body made of a stretchable material and having knots, the knots being repeatedly arranged at intervals and having diameters that vary according to the magnitude of axial tension applied to the rope body. Thus, the knot with the changed diameter is engaged with the eye portion of the shoe, so that the user can adjust the length of the shoelace without using a special tying method such as tying a bow-tie. Further, patent document 2 discloses a rope stopper with a spring. By attaching the cord stopper to the shoelace, the user can adjust the length of the shoelace without using a special tying method such as tying a bowknot. [ Prior Art literature ] [ Patent literature ] Patent document 1 Japanese patent application No. 5079926 Patent document 2 Japanese unexamined patent publication No. 5-34907 Disclosure of Invention [ Problem to be solved by the invention ] However, although the string described in patent document 1, which includes a tubular string body made of a stretchable material and having knots of which the size is changed, can be operated by a user with one hand, the string is configured to be adjustable in length only at the intervals between knots of which the size is changed, and thus does not have a shoelace locking/unlocking function at any position. Therefore, fine adjustment is difficult according to the preference of the user. In addition, although the cord stopper with a spring described in patent document 2 has a function of locking/unlocking a shoelace at an arbitrary position, a user needs to operate the cord stopper with one hand and adjust the length of the shoelace with the other hand. That is, basically, the user needs to use both hands to adjust the length of the shoelace, and the number of man-hours for the operation increases. The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a length adjuster for an umbilical member which has less man-hours for adjusting the length of a shoelace and has a locking/unlocking function at an arbitrary position desired by a user, as compared with a conventional length adjuster for an umbilical member. [ Means for solving the problems ] In order to achieve the above object, the invention according to claim 1 of the present invention is a length adjuster for umbilical members, comprising a main body member and a cover member that is displaced with respect to the main body member, wherein the main body member has a 1 st through hole, a2 nd through hole that is disposed on one side of the 1 st through hole, and a 3 rd through hole that is disposed on the other side of the 1 st through hole, and the main body member has a 1 st rod that is disposed between the 1 st through hole and the 2 nd through hole, and a2 nd rod that is disposed between the 1 st through hole and the 3 rd through hole, and the cover member has a lock member that is inserted into the 1 st through hole, and presses the umbilical members between the lock member and the 1 st rod and between the lock member and the 2 nd rod. In the invention according to claim 1, the invention according to claim 2 is characterized by comprising a recessed portion recessed downward in width in the up-down direction of a portion of the upper surface of the main body member where the cover member is located, wherein the position where the 2 nd lever is provided is located below the recessed portion and is located below the 1 st lever, and wherein the upper surface of the main body member and the upper surface of the cover member at the time of locking are smoothly continuous. The invention described in claim 3 is characterized in that, in addition to the structure of the invention described in claim 1 or 2, the lock member is provided at one end portion in the front-rear direction of the cover member, and an operation tab for operating the cover member is provided at the other end portion in the front-rear direction of the cover member, the operation tab protruding toward the other side in the front-rear direction. In the invention according to claim 4, in addition to the structure of the invention according to claim 1 to 3, the width of the lock member in the lateral direction is narrower than the width of the 1 st through hole in the lateral direction. In the invention according to claim 5, in addition to the structure of the i
