respective axes

6a, 7a intersect at an obtuse crossing angle α. In the illustrated example, the intersection angle α between the axis 6a and the axis 7a is 150 °. The crossing angle α can be obtuse, ie 90 ° <α <180 °, preferably 120 ° ≦ α ≦ 160 °. The crossing angle α affects the magnitude of the frictional resistance generated between the first line hole 6 and the second line hole 7 and the line L (see FIG. 8), and the larger the crossing angle α, the smaller the frictional resistance. The friction resistance increases as the angle α decreases. If the frictional resistance increases, the load applied to the first line hole 6 and the second line hole 7 increases, and if the load increases too much, the main body 2 may be damaged.
