。 This is a tube-type fixed contact in which a rod-shaped movable contact that moves back and forth in the axial direction approaches and separates. A holder that immovably supports a plurality of contact pieces in contact with the movable contact in the axial direction of the movable contact has a large diameter portion formed at the end on the movable contact side, and a holder that fixes the contact pieces on the outer circumferential surface of the small diameter portion following the large diameter portion. In a fixed contact of a disconnector formed in the shape of a hollow stepped shaft whose contact surface is in contact with a contact portion on a contact side, the holder moves the outer peripheral surface of the large diameter portion toward the movable contact side so that the outer diameter becomes smaller. A fixed contact structure of a disconnector characterized by being formed in the shape of a truncated cone.
