To be done. Further, the other end of the shaft 16 is formed in a disk shape having a diameter larger than the shaft diameter, and the winding portion 18 is fixed by bringing one end surface into contact with the disk portion. The winding unit 18 is supported by the shaft 16 and is mounted horizontally. The winding unit 18 of the embodiment is made of plastic.

The pin attachment body 20 has a ring portion 20a that is detachably attached to the other end of the winding portion 18, and a pin 30 that is erected with the base end portion embedded in the ring portion 20a. In the embodiment, the other end of the take-up portion 18 is formed with a slightly reduced diameter, and a steel ring 32, which is lightly press-fitted outside the reduced diameter portion, is fitted on the inner circumference of the ring portion 20a. That is, the pin attachment body 20 is attached to the winding portion 18 by lightly press-fitting the ring portion 20 a into the outer end surface of the winding portion 18.

The pins 30 are installed so as to make elastic contact with the outer peripheral surface of the winding part 18 when the ring part 20 a is mounted on the winding part 18, and are arranged at equal intervals in the circumferential direction of the winding part 18.
