Abstract
In the present disclosure, a pair of removing members (5) are provided to be able to move toward and away from each other. Each of the removing members (5) includes a nail (5A, 5B) capable of being inserted into a gap (S1) between a large diameter portion (11a) and an electrode tip (12), and a protrusion (54) extending in a direction intersecting with a direction of insertion of the nail (5A, 5B) into the gap. The protrusions (54) of one and the other one of the removing members (5) are axially supported respectively by first and second support portions (81a, 81b) provided on one end of an arm member (8). The first support portion (81a) is in the shape of a groove that is shaped to be gradually closer to the other one of the removing members as progressing toward the other end of the arm member (8).
