Electromagnetic relay with seal between cantact case and drive device

An electromagnetic relay, comprising:

• a fixed contact:
• a movable contact disposed to face the fixed contact;
• a movable contact piece connected to the movable contact, the movable contact piece being configured to move in an opening direction and a closing direction;
• a contact case that houses the fixed contact, the movable contact, and the movable contact piece;
• a drive device including a coil configured to generate an electromagnetic force to move the movable contact piece;
• an elastic member disposed between the drive device and the contact case to seal between the drive device and the contact case;
• and
• an inner case disposed in the contact case, the inner case including a hole into which the drive shaft is inserted and the inner case being disposed to face the drive device,
• wherein the elastic member is disposed between the drive device and the inner case to seal between the drive device and the inner case,
• the contact case includes an end surface, a first step portion located inside the end surface, and a second step portion located inside the first step portion,
• the elastic member is in contact with the first step portion, and
• the inner case is in contact with the second step portion.
