RELAY DEVICE

To suppress displacement of an electrode position of a relay device.SOLUTION: A vacuum relay 1 includes an insulating container 2, a COM (common) electrode terminal 3, an A contact electrode terminal 4 and a B contact electrode terminal 5 which are fixed to the insulating container 2, a movable electrode 6 provided to the COM electrode terminal 3, and a driving unit 7 for driving the movable electrode 6. A constricted portion 4a having a smaller diameter than the other portions is formed in the A contact electrode terminal 4. A cavity portion 4b extending in an axial direction of the A contact electrode terminal 4 is formed in the A contact electrode terminal 4. An adjustment screw (not shown) is screwed into the cavity portion 4b to adjust the length of the A contact electrode terminal 4. A constricted portion 5a having a smaller diameter than the other portions is formed in the B contact electrode terminal 5. A cavity portion 5b extending in an axial direction of the B contact electrode terminal 5 is formed in the B contact electrode terminal 5. An adjusting screw 9 is screwed into the cavity portion 5b to adjust the length of the B contact electrode terminal 5.SELECTED DRAWING: Figure 1 【課題】リレー装置の電極位置のずれを抑制する。【解決手段】絶縁容器２と、絶縁容器２に固定されるＣＯＭ（コモン）電極端子３、Ａ接点電極端子４およびＢ接点電極端子５と、ＣＯＭ電極端子３に備えられる可動電極６と、可動電極６を動作させる駆動部７と、を備える真空リレー１である。Ａ接点電極端子４に径が他の部分より小さい括れ部４ａを形成する。Ａ接点電極端子４に、Ａ接点電極端子４の軸方向に延びる空洞部４ｂを形成する。空洞部４ｂに調整用ねじ（図示せず）をねじ込んで、Ａ接点電極端子４の長さを調整する。Ｂ接点電極端子５に径が他の部分より小さい括れ部５ａを形成する。Ｂ接点電極端子５に、Ｂ接点電極端子５の軸方向に延びる空洞部５ｂを形成する。空洞部５ｂに調整用ねじ９をねじ込んでＢ接点電極端子５の長さを調整する。【選択図】図１
