Abstract
This component-part driving mechanism changes the relative position of a second member with respect to a first member and is provided with: a contact section that is provided to the first member; a biasing section that is an elastic lip that is provided to the second member and that accumulates biasing force as a result of changes in the distance between the contact section and the elastic lip, said biasing force serving to change the relative position in a predetermined direction; and a state maintenance section that maintains a state in which the elastic lip is in contact with the contact section. The relative position of the contact section and the elastic lip is made to change in the predetermined direction as a result of repeated accumulation and release of biasing force that is caused by vibration of the elastic lip relative to the contact section.
