Abstract
A contact device includes: fixed terminals; a movable contact maker; a pressing spring; an adjustment plate that comes into contact with an upper face of the movable contact maker; a holding portion; a movable shaft; and an electromagnet block. The holding portion is divided into first and second holding portions that are separated from each other. The first and second holding portions are electrically connected to each other via only the adjustment plate, due to the adjustment plate being sandwiched by a first side plate of the first holding portion and a second side plate of the second holding portion. The adjustment plate is moved in extending and contracting directions of the pressing spring, and the adjustment plate and each of the first and second side plates are subjected to resistance welding at a position at which pressing force of the pressing spring is a predetermined value.
