  • Electrical junction box
    Patent number: 9346422
    Abstract: An electrical junction box includes a bolt fixation portion made of resin, the bolt fixation portion having a bolt insertion hole through which a bolt is inserted to fix the electrical junction box to a vehicle. The bolt fixation portion includes a protrusion extending in an axial direction of the bolt in a state in which the bolt is inserted through the bolt insertion hole. The protrusion is configured to limit a rotationally movable range of an operating portion of a tool that is used in a state in which the operating portion extends in a direction intersecting the axial direction of the bolt.
