７はリトラクタ−で、端部にはりトラクターケース２に
内接する合成樹脂よりなるトップサポータ−８とテール
サポータ−９が固定されている。Reference numeral 7 denotes a retractor, and a top supporter 8 and a tail supporter 9 made of synthetic resin and inscribed in the tractor case 2 are fixed to the ends thereof.
このりトラクター７はりトラクターケース２内に摺動可
能に内装され、テールサポータ−９とリトラクタ−ケー
ス２のエンドカップ１０との間にはバネ１１が介装され
ている。The retractor tractor 7 is slidably installed inside the retractor case 2, and a spring 11 is interposed between the tail supporter 9 and the end cup 10 of the retractor case 2.
リトラクタ−７のトップサポータ−８の外側には軸方向
に溝１２が設けられ、この溝１２にリトラクタ−ケース
２に形成した突起１３が嵌合し、リトラクタ−７の回転
が阻止されている。A groove 12 is provided on the outside of the top supporter 8 of the retractor 7 in the axial direction, and a protrusion 13 formed on the retractor case 2 is fitted into the groove 12 to prevent rotation of the retractor 7.
