ABSTRACT:
A tilt sensor includes a light emitting element and two light receiving elements accommodated in a case. The case is formed with an inner space in which a rolling member is provided in a freely movable manner by the pulling force of gravity. A cover plate is fixed to the case to close the inner space. The cover plate is provided with an irregular, inner ceiling surface that is exposed to the inner surface so as to come into sliding contact with the rolling member.
