Reflector driving device

A reflector driving device, comprising:

• a reflector-retaining member configured to retain a reflector that refracts light;
• a first support member configured to support the reflector-retaining member so as to be swingable about a first axis;
• a second support member configured to support the first support member so as to be swingable about a second axis having an axis-line direction perpendicular to an axis-line direction of the first axis;
• a first driving mechanism configured to swing the reflector-retaining member about the first axis;
• a second driving mechanism configured to swing the first support member about the second axis;
• a first biasing member configured to bias the reflector-retaining member toward the first support member;
• and
• a second biasing member configured to bias the first support member toward the second support member,
• wherein the second driving mechanism includes a second magnetic field-generating member movable along with the first support member, and a second coil facing the second magnetic field-generating member,
• in a direction in which the second biasing member biases the first support member, a magnetic member disposed to be spaced from the second magnetic field-generating member is provided, and
• a restoring force of the second biasing member is greater than an attracting force between the second magnetic field generating member and the magnetic member.
