Pivotal micromotion device

摘要

A pivotal micromotion device includes a straight movable body, a pivotal body, and, a mechanism for transmitting and transforming a straight motion of the movable body to a pivotal motion of the pivotal body. The tramsmitting mechanism comprises an elastic reduced angular movement transmitting member having a fixed end located on the pivotal body side and a free end located on the movable body side, respectively, so as to be disposed between the movable and pivotal bodies; a first engagement member for engaging the free end of the transmitting member with the movable body; and second engagement member for engaging a position between the fixed and free ends of the transmitting member with a position near an outer periphery of the pivotal body.
