Abstract
In an electrode mounting device having a fixed coupling member and a removable coupling member, one coupling member has positioning projections and the other coupling member has a groove or grooves for receiving the positioning projections. These positioning projections are engaged with the grooves each other keeping a line contact or a point contact therebetween. As a result, if dust or chip is placed on the positioning projections or grooves of the coupling members, the coupling members can be accurately coupled. Furthermore, high precision is not necessarily required in preparation of the coupling members.
