A partitioning plate 30 is mounted on at least one of the inner surface plate 4a and right and left side surface plates 4b inside on the base side of the claw 4. A space 32 for storing foreign matter intruded inside the claw 4 is provided between the partitioning wall 30, the inner surface plate 4a, the bottom of the bracket 3, and the right and left side surface plates 4b.
