    Abstract: An electromagnetic relay includes a first fixed terminal, a second fixed terminal, a housing, a coil, and a spool. The second fixed terminal is disposed in front of the first fixed terminal and faces the first fixed terminal. The housing includes a side surface that laterally covers the first fixed terminal and the second fixed terminal. The coil is wound around the spool. The spool includes a support portion and a lateral wall portion. The support portion supports the first fixed terminal. The lateral wall portion extends from the support portion and is disposed between the first fixed terminal and the side surface of the housing in the left-right direction. The front end of the lateral wall portion is located between the first fixed terminal and the second fixed terminal in the front-rear direction.

    Abstract: An electromagnetic relay includes a fixed contact, a fixed terminal, a coil, an iron core, and a spool. The fixed terminal includes a contact support portion on which the fixed contact is provided. The coil is disposed behind the fixed terminal. The iron core includes a shaft portion and a head portion. The spool includes a hole and a flange. The shaft portion is disposed in the hole. The flange includes a first front surface and a second front surface. The hole is open at the first front surface. The first front surface is disposed rearward of and facing the head portion. The second front surface is disposed rearward of and facing the contact support portion. The second front surface is spaced a predetermined distance rearward from the first front surface. The predetermined distance is greater than the thickness of the contact support portion in the front-rear direction.

    Abstract: An electromagnetic relay includes a fixed terminal, a base, a fixed contact, a movable contact, a movable contact piece, and a movable terminal. The base supports the fixed terminal. The fixed contact is connected to the fixed terminal. The movable contact faces the fixed contact. The movable contact is connected to the movable contact piece. The movable terminal is provided separately from the movable contact piece and supported by the base. The movable terminal includes a support portion. The support portion is connected to the movable contact piece below the movable contact and supports the movable contact piece. The support portion includes an upper edge and a recess. The recess has a shape recessed downward from the upper edge at a position overlapping the movable contact piece.

    Abstract: A relay includes a fixed terminal, a movable contact piece, a holder, a drive shaft, a contact case, a magnetic field generation member, and an inner member. The drive shaft is connected to the holder on a side close to the first end of the drive shaft. The magnetic field generation member is arranged around the contact case and is configured to generate a magnetic field in which an arc generated between the fixed contact and the movable contact extends in a lateral direction of the movable contact piece. The inner member includes a rotation preventing portion for restricting rotation of the holder around the drive shaft. The rotation preventing portion is arranged so as to contact the holder at a position closer to a second end of the drive shaft than the movable contact piece and closer to the drive shaft than the movable contact.
