Claims

[Scope of utility model registration request]

A winding start end outlet 2 through which the cable winding start end a' is led out from the inside to the outside is formed on the side surface of the cable drum collar 1a, and a cylinder in the direction in which the cable winding start end a' is led out from the outlet 2. A body 3 is provided, and a fixing pawl 13 that can freely protrude inward through the through hole 19 is swingably attached to the outer surface of the cylindrical body 3, and a coil spring in a contracted state is installed between the fixing pawl 13 and the cylindrical body 3. 14c, the protruding end of the fixing claw 13 into the cylindrical body 3 is provided with a sharp protrusion 13a that can bite into the cable winding start end a', and inside the cylindrical body 3,
A piston plate 7 biased in the direction of the outlet port 2 by a spring 18 is provided so as to be movable in the direction of the cylinder axis, and the piston plate 7 extends from the piston plate 7 to the outside of the cylinder body 3 of the swinging shaft portion of the fixed claw 13. The locking rod 15 is led out through the elongated hole 16 in the axial direction, and a protrusion 13b is provided on the outer periphery of the swinging shaft portion of the fixed claw 13 to protrude toward the outlet 2,
The tip of the locking rod 15 abuts on this protrusion 13b, and the contact surface 17 at the tip is a downwardly inclined surface toward the tip of the fixing claw 13. The outlet side end 16a of the elongated hole 16
When the coil spring 14c is located at the opposite end 16b of the elongated hole 16, the fulcrum of the coil spring 14c to the fixed claw 13 is located inside the dead point d, while when the coil spring 14c is located at the opposite end 16b of the elongated hole 16, the fulcrum is outside the dead point d. A cable winding start end fixing device characterized by:
