Relay

A relay comprising:

• a fixed terminal including a fixed contact;
• a movable contact piece including a movable contact arranged to face the fixed contact, the movable contact piece being configured to move in a moving direction including a first direction in which the movable contact comes into contact with the fixed contact and a second direction in which the movable contact separates from the fixed contact;
• a holder that holds the movable contact piece;
• a drive shaft including a first end and a second end opposite to the first end, the drive shaft extending in the moving direction of the movable contact piece, the drive shaft being connected to the holder on a side close to the first end of the drive shaft;
• a contact case that accommodates the fixed contact, the movable contact piece, and the holder;
• a magnetic field generation member arranged around the contact case, the magnetic field generation member being 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;
• and
• an inner member that is a separate body from the contact case and that includes a rotation preventing portion for restricting rotation of the holder around the drive shaft, the rotation preventing portion being arranged so as to contact the holder at a position closer to the second end of the drive shaft than the movable contact piece and closer to the drive shaft than the movable contact, wherein
• the holder includes a plurality of contact portions configured to contact the rotation preventing portion, and
• the plurality of contact portions are arranged to face the rotation preventing portion in a longitudinal direction orthogonal to the lateral direction of the movable contact piece.
