  • Moderation feeling adding apparatus
    Patent number: 11907002
    Abstract: A base section can operate to one side and the other side in a predetermined direction. A contact section is attached to a spring and can be in contact with the base section. A holding section holds the spring. A wall portion faces the contact section in the predetermined direction, and generates a sound which becomes a moderation feeling by a collision between the wall portion and the contact section moved by a biasing force of the spring as a contact state between the contact section and the base section changes due to an operation of the base section. The holding section regulates a position of the spring at least in a predetermined direction. A clearance between the contact section and the wall portion is substantially equal on the one side and the other side in the predetermined direction.
