ELECTROMAGNETIC RELAY AND BASE

To ensure an arc space and suppress arc-over in spite of a simple configuration.SOLUTION: An electromagnetic relay 1 includes a fixed terminal portion, a movable portion having a movable contact 22 facing the fixed terminal portion, a movable shaft 25 for causing the movable contact 22 to approach to and separate from the fixed terminal portion, and a spring (contact pressure spring 23) arranged between the movable contact 22 and the movable shaft 25, and a base 51. The fixed terminal portion has a first fixed terminal and a second fixed terminal which is provided side by side with the first fixed terminal along a first direction. The movable shaft 25 extends along a second direction orthogonal to the first direction. The width of the movable contact 22 along the first direction is larger than the width thereof along a third direction orthogonal to the first direction and the second direction. The base 51 has a first inner wall and a second inner wall which face the movable portion in the third direction. The electromagnetic relay 1 further includes a first protruding portion and a second protruding portion that protrude from the first inner wall to the second inner wall in the third direction.SELECTED DRAWING: Figure 1 【課題】簡単な構成でありながら、アークスペースを確保し、かつ、弧絡を抑制する。【解決手段】電磁継電器１は、固定端子部と、固定端子部と向かい合う可動接触子２２と、可動接触子２２を固定端子部と接離させる可動軸２５と、可動接触子２２と可動軸２５との間に配置されているばね（接圧ばね２３）と、を有する可動部と、ベース５１と、を備える。固定端子部は、第１固定端子と、第１方向に沿って第１固定端子に並んで設けられた第２固定端子と、を有する。可動軸２５は、第１方向に直交する第２方向に沿って延びている。可動接触子２２は、第１方向に沿う幅が第１方向および第２方向に直交する第３方向に沿う幅よりも長い。ベース５１は、第３方向において可動部と向かい合う第１内壁及び第２内壁を有する。電磁継電器１は、第３方向において第１内壁から第２内壁へ向かって突出する第１突出部および第２突出部を更に備える。【選択図】図１
