摘要： An automatic speed reduction ratio switching apparatus is equipped with a sun gear connected to an input shaft, first and second carriers connected to a feed screw shaft, planetary gears meshed with the sun gear and which are mounted rotatably in the first and second carriers, and an internal gear meshed with the planetary gears and which is capable of movement in an axial direction. A packing member is arranged between the internal gear and the second carrier, for regulating movement in the axial direction of the internal gear, while enabling movement of the internal gear in the axial direction when a thrust force is applied at or above a predetermined value.

摘要： A ball screw mechanism is equipped with a ball screw shaft formed from a metallic material, a displacement nut inserted over an outer circumferential side of the ball screw shaft, steel balls installed between a first screw groove formed on the ball screw shaft and a second screw groove formed in the displacement nut, and a pair of first and second return members, through which the steel balls are circulated between one end side and another end side of the displacement nut. The first and second return members include main body parts mounted respectively onto one end and another end of the displacement nut, and cylindrical parts that project outwardly with respect to the main body parts. A return passage, through which the steel balls are circulated, is formed inside of the main body parts and the cylindrical parts.

摘要： An actuator is equipped with a cylinder body in the interior of which a piston is disposed for displacement therein. A piston rod connected to the piston projects outwardly to the exterior from an end of the cylinder body. A guide unit, having a guide body that is attached to the cylinder body, and a pair of guide rods, which are disposed displaceably with respect to the guide body, are disposed detachably on the cylinder body. Additionally, by mutually interconnecting the guide rods of the guide unit and the piston rod through a connecting plate, when the piston rod is displaced in an axial direction, the piston rod is guided by the pair of guide rods.
