Booster cable holding structure

A booster cable holding structure comprising:

• a structural body of insulating resin;
• and a clamping connection portion configured to be clamped by a clip of a booster cable and including a relief terminal and a resin terminal supporting portion, the relief terminal projecting in a plate shape from the structural body, and the resin terminal supporting portion being made of resin and projecting in a plate shape from the structural body with a surface thereof overlapping with the relief terminal, wherein the resin terminal supporting portion includes a first surface overlapping with the relief terminal, a second surface opposite to the first surface, and a tooth-edge surrounding wall on the second surface and extending away from the first surface and the second surface, the second surface is a pressed surface to be pressed by a plurality of teeth arranged in a width direction of a pressing surface of the clip in a state the clip clamps the clamping connection portion, and a wall inner surface of the tooth-edge surrounding wall closely surrounds each edge of at least two of the teeth of the clip or closely surrounds the edges of the at least two teeth together, so that each edge of the at least two of the teeth comes in contact with the corresponding wall inner surface of the tooth edge surrounding wall.
