Relay

A relay, comprising:

• a plurality of fixed terminals arranged to have fixed contacts;
• and
• a movable contact member arranged to have a plurality of movable contacts that are correspondingly opposed to the respective fixed contacts,
• the relay further comprising:
• a driving structure operated to move the movable contact member such that the respective movable contacts come into contact with the corresponding fixed contacts;
• a single first vessel configured to have a bottom and a plurality of chambers formed corresponding to the plurality of fixed terminals, and having insulating property, wherein the plurality of fixed terminals are inserted through and attached to the bottom, such that the plurality of fixed contacts are placed inside the first vessel and another part of the fixed terminals is placed outside the first vessel;
• a second vessel joined with the first vessel;
• and
• an air-tight space configured to include the plurality of chambers and formed by at least the plurality of fixed terminals, the first vessel and the second vessel to allow the movable contact member and the respective fixed contacts to be placed therein, wherein
• the first vessel has a partition wall member extended from the bottom to a position further away from the bottom than at least a position where the plurality of fixed contacts are located, with respect to a moving direction of the movable contact member, and arranged to part the plurality of chambers from each other, wherein
• the respective fixed contacts are placed in the respective chambers in the air-tight space.
