摘要： An electromagnetic relay includes a fixed contact, a movable contact piece, a movable contact, a contact case, a drive device, and an elastic member. The movable contact is disposed to face the fixed contact. The movable contact piece is connected to the movable contact. The movable contact piece is configured to move in an opening direction and a closing direction. The contact case houses the fixed contact, the movable contact, and the movable contact piece. The drive device includes a coil. The coil generates an electromagnetic force that moves the movable contact piece. The elastic member is disposed between the drive device and the contact case. The elastic member seals between the drive device and the contact case.
