  An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a longitudinal front view thereof, and FIG. 2 is a side view thereof. Reference numeral 1 denotes a synthetic resin winding bobbin that includes a bobbin main body 2. The bobbin main body 2 has a hollow cylindrical body 3 that is open at both ends, and annular flanges 4 and 4 ′ that project outward from the both ends of the body at a substantially right angle. A hollow cylindrical tube portion 5 serving as a shaft hole portion is concentrically arranged in the center portion of the body portion 3, and a plurality of the tube portions are arranged radially at equal intervals in the circumferential direction. The body 3 is integrally connected. The arm 6 has a length that is half of the axial length of the body 3 on the left and right (one end and the other end) with an annular plate 7 disposed at the axial center of the body 3 as a boundary. 6 pieces at an angle of 60 °, and are provided integrally with the left and right sides shifted in the circumferential direction by 30 °. A hollow cylindrical buttonhole 8 for rotational driving is integrally provided at a position close to the pipe portion 5 of every other arm 6 in the circumferential direction. In this example, the buttonhole 8 is formed of a large and small double short tube, but such a configuration is not necessarily required. 9 is an opening.

  The flange portions 4 and 4 'have a predetermined thickness, and a shallow ring-shaped recess 11 is formed on the outward surface thereof, and a plurality of ribs 12 are formed in the recess and aligned with the arm 6 in the radial direction. Are formed at regular intervals. A plurality of insertion holes 13 for the linear body 10 such as an optical fiber or an electric wire are provided at appropriate positions on the flange portions 4 and 4 ′ at intervals in the circumferential direction, and the body portion between the flange portions 4 and 4 ′. The linear body wound around the surface of 3 can be pulled out from the hole. In FIG. 1, reference numeral 14 denotes a winding start opening for hooking the starting end portion of the linear body 10 formed in a cutout in the body portion 3, and is a square hole.

  A press-fitting member 15 that temporarily fixes the terminal portion of the linear body 10 wound around the body surface is detachably fitted into the buttonhole 8. The press-fitting member 15 is made of a thermoplastic resin such as polystyrene, and as shown in FIGS. 3 and 4, a hollow cylindrical tube portion 16 that fits into the buttoned hole 8 and a diameter larger than the tube portion 16 at one end of the tube portion. It consists of a disc-shaped head 17 provided integrally. The other end portion of the cylindrical portion 16 is formed in a small-diameter portion 18 whose outer surface is notched so that it can be easily inserted during fitting. The head 17 has a convex shape whose surface is slightly inclined from the center toward the periphery. When the annular edge of the head portion 17 protruding outward from the cylindrical portion 16 is larger than the outer diameter of the buttonhole 8 and is larger in diameter, when the press-fitting member 15 is fitted into the buttonhole 8 or when the fitting is removed. It is a knob part 19.

  A plurality of vertical grooves 20 are formed in the cylindrical portion 16 at predetermined intervals in the circumferential direction as hole portions through which the end portions of the linear bodies 10 are inserted. In this example, four vertical grooves 20 are formed in a cross shape at equal intervals. The vertical groove 20 is notched from the other end of the cylindrical portion 16 toward one end, and is stopped near the head portion 17. The vertical grooves 20 are not necessarily formed in a cross shape, as shown in the drawing, but may be formed in a cross shape or in a manner of facing each other or not facing each other. Further, the hole does not necessarily have to be the longitudinal groove 20, and may be a through hole or a notch having a predetermined shape. Further, if the terminal portion of the linear body 10 can be temporarily fixed by, for example, being sandwiched between the press-fitting members 15, the hole portion is not necessarily required.
