DRIVING APPARATUS WITH TAPER SCREW AND ELASTIC DRIVING MEMBER TO DISPLACE OBJECT

摘要

A driving apparatus, which adjusts a position of a member to be driven, includes a driving member connectable with the member to be driven and made of an elastic member, a female screw that penetrates the driving member, and a taper-shaped male screw configured to be screwed into the female screw. The driving member has a cutting portion that penetrates in an axis direction of the female screw so that an inner circumference of the female screw is discontinuous, and the driving member is configured to move in an axis direction of the male screw in a state where the male screw is screwed into the female screw to displace the member to be driven in a direction orthogonal to the axis direction of the male screw.

1. A driving apparatus that adjusts a position of a member to be driven, the driving apparatus comprising:
a driving member connectable with the member to be driven and made of an elastic member; a female screw that penetrates the driving member; and a taper-shaped male screw configured to be screwed into the female screw, wherein the driving member has a cutting portion that penetrates in an axis direction of the female screw so that an inner circumference of the female screw is separated into a plurality of regions and is discontinuous, wherein centers of the inner circumferences of the female screws are displaced from each other so that the inner circumferences of the separated female screws are close to each other, and wherein the driving member is configured to move the male screw in an axis direction of the male screw in a state where the male screw is screwed into the female screw to displace the member to be driven in a direction orthogonal to the axis direction of the male screw.
