Thus, the friction member 321 can be replaced without detaching the guide holder 323, thereby facilitating replacement of the friction member 321.
The opening direction of the attaching/detaching port 323b is the same as the rotation direction of the tension disc 310 (not shown). Since the opening direction of the attaching/detaching port 323b is the same as the rotation direction of the tension disc 310, the friction member 321 is restricted by the inner wall of the guide passage 323a when the tension disc 310 rotates, and the friction member 321 can be prevented from coming out of the guide passage 323a from the attaching/detaching port 323 b.
