Furthermore, in the above-described embodiment, since the common hole 19 and the common tubular portion 39 have long shapes in the circumferential direction of the frame main body 11, the work of inserting the string 20 into the common tubular portion 39 can be facilitated.

• the directions of the central axes of the holes 87 and 88 greatly differ from the normal direction of the frame main body 11 in angle, and are similar to the tangential direction of the frame main body 11. For this reason, the tip end of the drill blade for processing the holes 87 and 88 easily slides at the groove portion 11b and the inner peripheral surface 11c of the frame main body 11, and it becomes difficult to form the holes 87 and 88.
