Feeding mechanism and manufacturing method thereof

The invention provides a feeding mechanism which has a small number of components and is suitable for miniaturization. A feed mechanism (1) is provided with: a base (2); a movable body (3); a feed screw (4) that moves the movable body (3) relative to the base (2); and a torque generating member (15) on which an internal thread (15b) screwed with the feed screw (4) is formed. A housing hole (12) extending in a direction orthogonal to the feed screw (4) is formed in the movable body (3), and the torque generating member (15) is housed in the housing hole (12). 本申请提供部件数量少并且也适于小型化的进给机构。进给机构(1)具备：基座(2)；可动体(3)；进给丝杠(4)，其使可动体(3)相对于基座(2)移动；以及转矩产生构件(15)，其供与进给丝杠(4)螺合的内螺纹(15b)形成。在可动体(3)形成有沿与进给丝杠(4)正交的方向延伸的收容孔(12)，并将转矩产生构件(15)收容于收容孔(12)。
