Abstract: An electromagnetic contactor comprises: fixed contact pieces 3 including fixed contacts 9; an electromagnet unit 5 to which a movable contact piece 4, the movable contact piece 4 including movable contacts 10, the movable contacts 10 coming into contact with and being separated from the fixed contacts, is joined via a contact support 11; and a hermetically sealed container 2 configured to contain the fixed contact pieces, the movable contact piece, and the electromagnet unit in the same space, wherein in the electromagnet unit 5, unit-side joining portions 25a and 25b, the unit-side joining portions 25a and 25b being joined to container-side joining portions 33 and 36 arranged on the hermetically sealed container from the direction of movement of the movable contact piece, respectively, are arranged, and flat plate-shaped spacers 34 and 37 by which an inter-contact gap G between the fixed contacts and the movable contacts is adjusted are arranged interposed between the container-side joining portion and the unit-side joining portion.

Abstract: To more effectively prevent separation of a contact unit at the time of short-circuit in an electromagnetic contactor. A capsule case is made of resin. A fixed yoke is arranged between a pair of fixed contact pieces, and at least a portion of the fixed yoke is held in a skeleton forming a capsule case. A movable yoke is disposed on a movable contact piece and is opposed to the fixed yoke. The fixed yoke and the movable yoke attract each other caused by a magnetic circuit being formed about an axis in a conduction direction in which current flows in the movable contact piece when a contact unit is closed.
