COMPONENT-PART DRIVING MECHANISM

摘要

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.

主权项

1. A component-part driving mechanism that changes a relative position of a second component part relative to a position of a first component part, comprising:
an abutting section provided for the first component part; an urging section provided for the second component part and accumulates an urging force as a result of changes in a distance between the abutting section and the urging section, said urging force serving to change the relative position in a predetermined direction; and a state maintaining section that maintains a state in which the urging section is abutting against the abutting section, wherein the abutting section and the urging section displace the relative position in the predetermined direction as a result of a repetition of accumulating and releasing of the urging force due to vibration of the urging section relative to the abutting section.
