    摘要： A compact lower guide unit that allows the electrode guide to be attached and detached more easily and reliably. Provided is a lower guide unit including a housing, an electrode guide, and a pull-up mechanism having a guide support, links, and a power cylinder. The guide support includes a biasing member and a displacement member. The biasing member can bias the displacement member, and the displacement member can be displaced between a restriction position and a release position. The links can be rotated by a force applied by the power cylinder. The electrode guide is fixed to the guide support by a biasing force of the biasing member when the displacement member is in the restriction position, and the electrode guide is released from the lower guide unit when the displacement member is displaced to the release position.
