By concave-convex mating of the lock grooves (59) and the lock claws (49a) with each other, the arm shank (40) is restricted from rotating by β degrees (about 22 degrees) or more with respect to the arm head (50), and a state in which the arm shank (40) stands up by α degrees (about 20 degrees), which is smaller than β degrees, with respect to the arm head (50) is maintained.",
