  • Patent number: 11728580
    Abstract: A terminal includes: a flat surface portion; an extending portion continuous with the flat surface portion; a branch portion continuous with the extending portion and extending in a direction different from that in which the extending portion extends; and rotation stop portions continuous with the branch portion. When the terminal is attached to a bolt protruding from a fixing member and including a seat separated from the fixing member, the flat surface portion contacts the seat, the rotation stop portions extend from the branch portion toward a base end of the bolt in a protruding direction of the bolt, and at least a pair of the rotation stop portions are positioned to sandwich the seat in a direction intersecting the protruding direction to prevent rotation of the terminal with respect to the bolt.
