1. A spot welding electrode housing apparatus for housing electrodes for use in spot welding in such a manner that each of the electrodes is mountable on an end of a shank of a welding gun, the apparatus comprising:
a rotor including a plurality of recesses opening in a same direction around a rotation axis and a hollow portion therein, each of the recesses receiving a corresponding one of the electrodes inserted therein from a distal end thereof and housing and holding the corresponding one of the electrodes such that a base end of the corresponding one of the electrodes mounted on the shank partially juts out of an opening of each of the recesses; a biasing member housed in the hollow portion, and configured to rotationally bias the rotor toward one direction around the rotation axis; and a rotation regulator positioned adjacent to the rotor in a direction of the rotation axis, and configured to allow the rotor to abut against a side surface of the base end of one of the electrodes mounted on the shank and housed and held in a corresponding one of the recesses and thereby to regulate a rotation of the rotor toward the one direction around the rotation axis when the rotor is allowed to rotate toward the other direction around the rotation axis against a biasing force of the biasing member. |
