Description

（１）本発明の一形態によれば、それぞれ固定接点を有する複数の固定端子と、；各前記固定接点にそれぞれ対応する複数の可動接点を有する可動接触子と、；鉄心および前記鉄心と繋がる可動軸を有し、前記可動接触子を前記複数の固定端子に接触させるために前記可動接触子を移動させる駆動機構と、；前記複数の固定端子と接合される第１の容器と、；前記可動接触子、各前記固定接点および前記可動軸が収容される気密空間を前記第１の容器および前記複数の固定端子と共に形成し、かつ、前記可動軸が挿通される第１の貫通孔が形成されているベース部を有する第２の容器と、；前記第１の容器と前記第２の容器とを接合する接合部と、を備える継電器が提供される。この形態の継電器は、前記ベース部の上面に配置されているとともに、前記可動軸が挿通される第２の貫通孔が形成され、絶縁性材料からなるケース部材と、；前記ケース部材を保持するケース保持部材であって、前記ケース部材を前記ベース部とともに挟む押さえ部と、；前記鉄心もしくは前記ベース部に保持固定される固定部と、を有するケース保持部材と、を備える。この形態の継電器によれば、ケース部材は、ベース部とケース保持部材との間に狭持されて固定される。従って、単純な構造で簡易にケース部材を固定することができる。 (1) According to one aspect of the present invention, a plurality of fixed terminals each having a fixed contact; a movable contact having a plurality of movable contacts corresponding to each of the fixed contacts; and an iron core and the iron core A drive mechanism having a movable shaft and moving the movable contact to bring the movable contact into contact with the plurality of fixed terminals; a first container joined to the plurality of fixed terminals; An airtight space for accommodating the movable contact, each of the fixed contacts and the movable shaft is formed together with the first container and the plurality of fixed terminals, and a first through hole through which the movable shaft is inserted is formed. There is provided a relay comprising: a second container having a base portion that is configured; and a joint for joining the first container and the second container. The relay of this form is disposed on the upper surface of the base portion, and has a second through hole through which the movable shaft is inserted, and a case member made of an insulating material; and holds the case member a case holding member, a pressing portion sandwiching the case member together with the base portion; and a case holding member having a fixed portion held fixed to the core or the base unit. According to the relay of this form, the case member is sandwiched and fixed between the base portion and the case holding member. Therefore, the case member can be easily fixed with a simple structure.

（５）上記形態の継電器において、前記固定部は、前記押さえ部から前記可動軸の軸線方向に沿って延伸するように形成されていてもよい。この形態の継電器によれば、固定部が延伸して形成されているので、ケース保持部材を更に安定して固定できる。 (5) In the relay of the above embodiment, the fixing portion may be formed so as to extend along the axial direction of shaft the accepted from the pressing portion. According to the relay of this form, since the fixing portion is formed by extending, the case holding member can be fixed more stably.
