ABSTRACT:
A feed screw mechanism includes a linearly movable member which supports a pin and a lead screw which rotates while being in mesh with the pin, so that the rotation of the lead screw causes the linearly movable member to linearly move. The linearly movable member includes a linear movement adjusting device which adjustably supports the pin in a direction perpendicular to an axis of the lead screw, a rotation adjusting device which rotatably supports the pin in a plane including the pin, and a locking member which locks the pin is a predetermined position.
