1. A spring connector comprising:
a tube;
a movable pin having a distal end portion that protrudes from an opening of the tube, and having a hole portion that opens on a side opposite to a protruding direction; and
a coil spring configured to bias the movable pin in the protruding direction,
wherein the coil spring includes an eccentric winding portion whose winding center is eccentric relative to an axial straight line connecting a winding center of a winding portion at one end portion and a winding center of a winding portion at an other end portion,
wherein the one end portion is located at a position where an angle formed by a line extending from a base point indicating a position of the axial straight line toward the winding center of the eccentric winding portion and a line extending from the base point toward the one end portion is 90 degrees or more and 270 degrees or less in a clockwise direction in a plan view from a linear direction of the axial straight line, and
the other end portion is located at a position where an angle formed by the line extending from the base point toward the winding center of the eccentric winding portion and a line extending from the base point toward the other end portion is 90 degrees or more and 270 degrees or less in the clockwise direction in the plan view.
