摘要： A motion transforming mechanism comprises a plate assembly and a toothed rail. The plate assembly is constituted by at least three rotation plates having a common rotation axis and each having a plurality of teeth, the rotation plates being respectively formed with cranked through bores. The toothed rail is formed with a plurality of teeth held in mesh with the teeth of rotation plates. The motion transforming mechanism further comprises a drive motor assembly constituted by a rotor unit rotatably received in the cranked through bores and a stator unit accommodated in the rotor unit. The rotation plates are rotated with respect to their common rotation axis by the rotation of the rotor unit with respect to stator unit. The motion transforming mechanism thus constructed requires no external electric motor and accordingly is able to be more easily assembled with various systems.

摘要： A fluid is supplied and discharged to and from a cylinder. A body portion is fixed to a fixed-side structure, and the cylinder is provided integrally with the body portion. A piston defines a cylinder chamber inside the cylinder and slides on an inner wall of the cylinder. A rod is provided integrally with the piston and is displaced so as to extend from and contract into the cylinder. A link member is installed parallel to the axial direction of the cylinder or installed so as to extend obliquely to a direction parallel to the axial direction of the cylinder, and a first end of the link member is pivotably connected to a movable-side structure. A connecting member is fixed to the rod, and a second end of the link member is pivotably connected to the connecting member.

摘要： An object of the present invention is to provide an electric actuator having a structure capable of reducing an external force or impact acting on a screw shaft when a piston rod is at a stretched position. An electric actuator includes a nut, a piston rod, recesses, keys, holes, and a tapered portion. Into the nut, a screw shaft is screwed. The piston rod moves linearly via the nut. The recesses are formed on an outer circumferential surface of the nut. The keys are each provided to a recess. The tapered portion is formed on an inner wall of the cylinder body. The piston rod advances to move the keys outward to cause the keys to fit to the tapered portion to block retraction of the piston rod.
