  "abstract": "A bus bar that includes a main body having a plate shape for arranging a terminal to be electrically connected to the bus bar; and an upright provided at a side in a widthwise direction of the main body, wherein: the main body has an open hole into which a shaft of a bolt is to be inserted, and the upright has an inner surface with which a head of the bolt can come into contact in a rotational direction.",
  "claims": [
    "1. A bus bar, comprising: a main body having a plate shape for arranging a terminal to be electrically connected to the bus bar; and a first upright and a second upright provided at opposite sides in a widthwise direction of the main body, wherein: the main body has an open hole into which a shaft of a bolt is to be inserted, the first and second uprights respectively have a first inner surface and a second inner surface with which a head of the bolt can come into contact in a rotational direction, the open hole is separate from the first and second uprights, is spaced from the first and second uprights, and is arranged to at least partially overlap with the first and second uprights in a lengthwise direction of the main body, and the main body has a first recess adjacent to the first upright and a second recess adjacent to the second upright with the first recess between the open hole and the first upright and the second recess between the open hole and the second upright.",
    "2. The bus bar according to claim 1, wherein the first and second uprights oppose each other with the open hole therebetween, and are arranged so as to at least partially overlap with each other in a lengthwise direction of the main body in a side view of the main body.",
    "3. The bus bar according to claim 2, wherein: the head of the bolt has a quadrangular column shape, and the first and second inner surfaces are configured such that two diagonal corners of the head having the quadrangular column shape can both come into contact with the first and second inner surfaces.",
    "4. The bus bar according to claim 2, wherein: the main body has a first cutout adjacent to the first upright, and a second cutout adjacent to the second upright, and the first cutout and the second cutout are provided at different positions in the lengthwise direction so as not to overlap with each other in the lengthwise direction in the side view of the main body.",
    "5. A wire harness comprising: a first electric wire; a second electric wire; and a bus bar comprising: a main body having a plate shape for arranging a terminal to be electrically connected to the bus bar; and a first upright and a second upright provided at opposite sides in a widthwise direction of the main body, wherein: the main body has an open hole into which a shaft of a bolt is to be inserted, the first and second uprights respectively have a first inner surface and a second inner surface with which a head of the bolt can come into contact in a rotational direction, the open hole is separate from the first and second uprights, is spaced from the first and second uprights, and is arranged to at least partially overlap with the first and second uprights in a lengthwise direction of the main body, the main body has a first recess adjacent to the first upright and a second recess adjacent to the second upright with the first recess between the open hole and the first upright and the second recess between the open hole and the second upright, and the first electric wire is electrically connected to the second electric wire via the bus bar."

  "description_excerpt": "The present disclosure relates to a bus bar and a wire harness.\n\nJP 2018-170098A describes a fixing structure for a bus bar and a terminal. In this fixing structure, the bus bar is arranged on an electrode pole side of a battery in order to connect a plurality of batteries in a battery pack, and the terminal is arranged on a surface of the bus bar in order to detect the voltage of the battery.\n\nIn this fixing structure for a bus bar and a terminal, an electrode pole of the battery is inserted into an open hole in the bus bar, and the electrode pole of the battery is inserted into an open hole in the terminal. A nut is then fastened to the electrode pole of the battery, the terminal is fixed to the bus bar, and the bus bar and the terminal are electrically connected.\n\nJP 2018-170098A also describes a detent for the terminal for use when the nut is fastened.\n\nIn the above fixing structure described in JP 2018-170098A, the bus bar is fastened by the nut to the electrode pole of the battery, which is not rotatable. The inventor of the present application studied a fixing structure for fixing a bus bar to a rotatable bolt. The inventor of the present application examined a reference example in which, when a nut is fastened, an anti-rotation wall portion that comes into contact with a polygonal head portion of the bolt is provided in a housing made of synthetic resin for supporting or accommodating the bus bar, thereby suppressing rotation of the bolt.",
