Abstract
The present invention relates to a driving unit capable of implementing a long stroke drive while achieving height reduction of the driving unit. The driving unit is provided with a driving mechanism for driving a driven body. The driving mechanism includes: a bendable displaceable member that is fixated at one end and, through electric control, bent and displaced at the other end; a driving direction-changing member changing a direction of the bending and displacement of the bendable displaceable member to a driving direction of the driven body, the driving direction of the driven body being perpendicular to the direction of the bendable displaceable member; a contact member frictionally engaged with the driving direction-changing member and driving the driven body; and a precompression member mounted in the driven body and precompressing the contact member towards the driving direction-changing member.
