PROBLEM TO BE SOLVED: To provide a winding mechanism in a reel in which the adjustment of a length of a string-like object such as a cord of an electric product and wire for fall prevention can be performed by a simple operation.SOLUTION: A winding mechanism comprises a reel biased by a spiral spring and having means for winding up wire. The winding mechanism is characterized in that: a stopper (2) fitted in a groove (3) for stopper movement provided inside an exterior b(7) is moved by the shape of a groove provided on a reel groove surface (8) to adjust a length of a string-like object the stopper (2) is circulated through the same path in the groove and extended by a guide plane provided on the grooved surface when pulled once, and the length is locked by the guide plane and a stopper tray (25) when released and the stopper (2) is guided to the guide plane (26) from an outer groove to an inner groove when continued to be pulled, and then is circulated through the same path in the groove again and the locking is released so as to circulate through the outer groove before being guided to the guide plane (26) from the outer groove to the inner groove when briefly pulled and released, and is wound up.COPYRIGHT: (C)2015,JPO&INPIT【課題】 電気製品のコードや落下防止のワイヤー等、紐状の対象の長さの調節を簡単な操作で行えるようにする、リール内部の巻き取り機構を提供する。【解決手段】 ゼンマイにより付勢され、ワイヤーを巻き取る手段を有するリールからなる巻き取り機構であり、外装b(7)の内側に設けたストッパー移動用の溝(3)に嵌め込んだストッパー(2)が、リール溝面(8)に設けた溝の形状により移動し、紐状の対象の長さを調節し、一度引っ張ると溝面に設けた誘導面によりストッパー(2)は溝内の同じ経路を循環し伸び、離すと誘導面とストッパー受け(25)により長さがロックされ、再び引き続けると外溝から内溝への誘導面に誘導(26)された後、再び溝内の同じ経路を循環し、短く引っ張るようにしてから離すと、外溝から内溝への誘導面(26)に誘導される前に、外溝を循環するようにロックが解除され、巻き取られる事を特徴とする、巻き取り機構。【選択図】図4
