り機構。A frame supporting a moving object in a linearly movable manner, and a screw rotatably supported on the frame parallel to the moving direction of the moving object and screwed into a female thread fixed to the moving object. A feed shaft having a shaft, a feed shaft provided with a torsion groove or a ridge rotatably and slidably supported on the frame body, and a portion that fits into the torsion groove or ridge of the feed shaft and prevents movement in the axial direction. a rotation connecting member that is rotatably supported on the feed shaft and transmits rotation to the screw shaft; a first drive member that is located outside the frame and does not rotate the feed shaft (transmits it in the axial direction); A minute feed mechanism comprising: a second drive member provided on the frame or drive member side to return the feed shaft; and a member provided inside the frame to prevent rotation of the connecting member during the return stroke of the feed shaft. .
