    摘要： The contact device includes a main contact mechanism that includes a pair of main fixed contacts and a main movable contact elastically supported by a movable shaft and disposed to be contactable with and separable from the pair of main fixed contacts, an auxiliary contact mechanism that includes a pair of auxiliary fixed contacts and auxiliary movable contacts disposed in an auxiliary contact holding member connected to the movable shaft so as to be contactable with and separable from the pair of auxiliary fixed contacts, and a contact housing portion that houses the main contact mechanism and the auxiliary contact mechanism. The movable shaft has a main contact support portion supporting the main movable contact and an auxiliary contact support portion supporting the auxiliary contact holding member. The main contact support portion and the auxiliary contact support portion are connected to each other via the auxiliary contact holding member.

    摘要： There is provided an electromagnetic contactor that ensures appropriately preventing a foreign matter from invading an auxiliary contact mechanism housing chamber from a main contact mechanism housing chamber via a through-hole on a partition wall; and a foreign matter from invading the main contact mechanism housing chamber from the auxiliary contact mechanism housing chamber via the through-hole on the partition wall. With an electromagnetic contactor (1), a main contact mechanism housing chamber (A) and an auxiliary contact mechanism housing chamber (B) are partitioned by a partition wall (10). The partition wall (10) has a through-hole (10a) through which a coupling shaft (34) is inserted. A foreign matter invasion prevention mechanism (60) is provided at a peripheral area of the through-hole (10a).
