Electrical junction box

1. An electrical junction box comprising 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,

wherein the bolt fixation portion comprises a protrusion extending in an axial direction of the bolt in a state in which the bolt is inserted through the bolt insertion hole, and

wherein 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 to a range of rotational movement that is an acute angle or a right angle.

2. The electrical junction box according to claim 1 , wherein the protrusion is configured as a bolt surrounding wall arranged around the bolt insertion hole, and

wherein the bolt surrounding wall has a slit configured to allow the operating portion to be inserted and removed from the slit and to limit the rotationally movable range of the operating portion.

3. The electrical junction box according to claim 2 , wherein the bolt surrounding wall is configured to restrict an access of the tool from the direction intersecting the axial direction of the bolt.

4. The electrical junction box according to claim 2 , wherein the bolt surrounding wall is configured to have a substantially circular shape in a plan view.

5. The electrical junction box according to claim 2 , wherein the slit is configured such that an angle formed by lines connecting a center of the bolt insertion hole and respective sides of the slit is an acute angle or a right angle.

6. The electrical junction box according to claim 1 , wherein the bolt fixation portion further comprises a radial wall extending outward in a radial direction from the bolt insertion hole and the protrusion extends in the axial direction from the radial wall.
